JANUARY-FEBRUARY 1970 OBSERVATIONS ON THE FIRST NORTH AMERICAN BREEDING OF THE SPOT-WINGED WOOD QUAIL {Odontophorus capueira) By G. Michael Flieg (St. Louis Zoological Park, Missouri, U.S.A.). The Spot- Winged Wood Quail, also known as the Capueiria Partridge or Uru, is a small stocky game-bird found on the ground in the dense tropical forest of eastern Brazil, Paraguay and northeastern Argentina. It is very beautiful, but not gaudy. The ventral parts are lead grey, the back is spotted brown and black, and there is red bare skin around the eyes. It has cinnamon eyebrows and a dark spot behind the eye. The overall size is just a bit larger than that of the Bob White ( Colinus virginianus). This species was fed on game bird crumbles and trout chow. It was kept in a heated barn when the weather dropped to less than 45 0 F. These birds are kept in the barn normally from November through March and have free choice at other times barring very inclement weather. In April 1965 three Spot- Winged Wood Quail began to build a nest in their cage at the St. Louis Zoo. They were housed with Cinereus Tinamou ( Nothoprocta cinereus) in a pheasant aviary 7x3m. Although the sexes were undetermined, we have since found out that two males and one female were involved in nest building. They gathered nesting material by picking it up and throwing it over their shoulders to the next bird in the line, finally transporting it to the nest site. The unique nest of the genus Odontophorus is domed and about 40 x 50 cm. in size and is similar to the nests of many neotropical passerines. The domed nest took about three days to complete, and five white, size 40 x 28 mm. eggs were laid at daily intervals. These were removed and a second clutch of three eggs was laid about two weeks later. Three eggs hatched on 14th May 1965 after an incubation period of 26-27 days, although one pipped 10th May 1965, four days prior to hatching. The newly hatched young looked very much like Bob White, ( Colinus virginianus ), but were a bit larger with blood red beaks and dark legs. Although they grew very quickly at first, when they reached about half the size of the adult they slowed down and did not reach full size until about two months old. A 2 C. J. O. HARRISON — HELPERS AT THE NEST IN THE PURPLE GALLINULE At this age they still had not developed contour feathers on the back and rump. At the age of three and a half months they could be detected from the adults only by darker colouration and grey cheeks. This breeding by the St. Louis Zoological Garden was cited as a first in North America by the American Game Bird Breeders Cooperative Federation. We would surely like to know if it could be a first captive world breeding and would appreciate hearing to the contrary. * * * HELPERS AT THE NEST IN THE PURPLE GALLINULE (Porphyrio porphyrio ) By C. J. O. Harrison (Perivale, Middlesex, England) It is well known that the young of the first brood of the Moorhen, Gallinula chloropus , in each year will help to feed the young of the second brood, often taking food from the parents and passing it on to the younger chicks; but such sociability ceases at the end of the season. Ridpath (1964) found that the large flightless rail, the Tasmanian Native Hen, Tribonyx mortierii , might form groups of three or four birds instead of pairs, and that such groups, which remained together persistently, consisted of several males with one female. This social behaviour does not, however, appear to have been more widely noted in the rail family, but as in the case of the Purple Gallinule, P. porphyrio , this may be due to the fact that behaviour which becomes apparent in an open aviary is very difficult to observe with much more timid birds in the depths of a swamp or reedbed. The Snowdon Aviary of the London Zoo houses, among other species, some individuals of the pale-headed Indian race of the Purple Gallinule, P. porphyrio poliocephalus (this is the Old World species, not the North American Purple Gallinule, Porphyrula martinicd). The birds of this race are a light purplish blue with a paler, whitish head, and the usual white under tail coverts and red bill and legs. They have bred in this aviary for several successive seasons. On a visit during July 1968 I noticed two adults with three half-sized young in blackish down with smooth foreheads. A third adult was collecting a bill full of grass and leaves which looked like nest material. It walked towards the other two, one of which joined it, followed by two of the chicks. The third bird dropped the material it was holding and these two adults and young went to a food tray where the adults fed the young. Even at this stage one of the young tried to emulate adults by holding food up in one foot and balancing on the other, although not with complete success. The other adult and other young one remained at the nest-site. As far as I was aware the adults should have been a pair and the young of a previous year. C. J. O. HARRISON — HELPERS AT THE NEST IN THE PURPLE GALLINULE 3 Next year, at the end of August 1969, I made further observations. The aviary appeared to have seven apparently adult birds. There was one group of four which moved around the lower part of it, near the canal. There were another two which kept together and did not normally approach to within more than nine or ten feet of the others, but would occasionally pass more closely when moving from one part to another or to food trays, and appeared to share some of the area. One odd bird was alone in an upper corner of the aviary. It was not possible to distinguish any obviously immature birds among these. F rom my observations it appeared that the group of four constituted a social unit, but there was no sign of any interaction with the other two birds nearby, nor was it possible to assign any particular role to any one of the four, as the following notes indicate. I had previously seen three of the four squatting close together, one apparently on a nest, near the S.W. corner of the aviary. Two were now resting with bodies pressed together on a more central site near the main pool and among growing plants, no. 1 just resting, no. 2 with a wing held a little apart from the body, the pale bill and dark head of a chick just visible under the wing. No. 2 broke off small pieces of surrounding plants and fed them to the chick. No. 3 stood near no. 2 and also fed the chicks at intervals. From subsequent brief views at least three chicks were present. Occasionally no. 3 passed food items to no. 2 who gave them to the chicks. No. 4 appeared carrying a piece of food and broke off pieces which it passed to no, 3 who fed the chicks directly or passed it to no. 2 for them. No. 4 moved off, returned with more food and this time stood near no. 3 and passed the food directly to no. 2 who fed the chicks with it. After a pause, no. 4 thrust its head and neck under no. 2, forced its way under and pushed no. 2 off the chicks, taking over the brooding. No. 2 now left the nest and walked to where no, 3 was breaking up a large piece of food held down in its foot. No 3 then began passing small pieces of food to no. 2. Some of these were eaten, but in several instances a small piece of food was passed backwards and forwards a number of times before finally being eaten by one or the other. The piece of food would be held in the bill by one bird, and taken from the bill by the other bird. Later I noticed that when young were being fed, if a piece of food proved too large for them to swallow, the adult would repeatedly take it back from the bill of the young one and then offer it again; and if two adults were present they might repeatedly take it from each other’s bill before passing it back to the chick. The repeated taking of the fragment from another bird’s bill appears to result in the food being broken into successively smaller pieces ; and I think that this passing back and forth, and retrieving from the bill of the chick, is behaviour which results in portions too large to swallow being broken down to a convenient size for eating. The passing of small morsels between the two adults in the instance above probably arose from the fact that their feeding was associated with the presence of young birds. 4 K. S. HARRAP — BREEDING OF THE LARK-LIKE BUNTING After a break in observation I returned later to find one bird brooding the young while the others were scattered, odd individuals bringing food at intervals. Towards the end of the afternoon two of the four birds were seen collecting bills full of leaves and grass, apparently nest material, and passing this to the bird brooding the chicks who built the material up around itself as a nest, probably a temporary structure on which to brood the young.

Harrap (West Somerton, Bellevue, Bulawayo, Rhodesia) Lark-like Buntings, Fringillaria impetuani , are a pale edition of the well-known Cinnamon Rock Bunting, Fringillaria tahapisi , their size being about that of the European Linnet. Description Male , Adult. Head. Crown and nape, buffy brown, finely streaked olive-brown. Upper parts. Mainly buffy-brown with streaking on mantle. Under parts. Throat, pinkish buff; breast, tawny olive changing to dark buff on belly; under wing coverts and axillaries, pinkish buff. Tail. Olive-brown. Bill. Upper Mandible, slate; lower mandible, flesh colour. Female , Adult. Resembles male, perhaps lighter on wings. Juvenile. As adult. This bird is very nomadic in habit and will invade an area, stay for several months then completely disappear, especially here in Rhodesia. A bird of dry country, it seems to favour Matabeleland which is in the southern part of the country. One of these invasions was in 1962 and several were trapped by local aviculturists. My pair were two of these and, as they showed no signs of breeding over the years, were classified as two of a sex. The birds came into my possession in 1968 and were put in an aviary 20 ft. x 16 ft. with Rock Buntings, Golden Breasted Buntings, Finch Larks, Quail Finches, Waxbills of several species, and Doves as companions. K. S. HARRAP — BREEDING OF THE LARK-LIKE BUNTING 5 The two birds completely ignored one another until August of 1969 when one was seen singing lustily from a rock in the aviary, stopping only to chase the other round the aviary with drooped wings, not unlike the courtship of the domestic canary. A week or so later I missed the female and on searching through the aviary I found her sitting on two brown speckled eggs in a little nest made at the base of a large clump of bamboo. The composition of the nest was mainly coarse grass bents and small broken twigs, the lining consisted mainly of the fine down from Pampas Grasses and Hessian taken from an old sack which had been placed in the aviary to attract white ants (termites). Both eggs hatched after being incubated by the female only for about twelve days. The chicks were covered in a long white down but un¬ fortunately I could not see the skin colour as the hen sat very close. Pin feathers were observed growing on the young at a week old and both left the nest at fourteen days, their tails being half grown. Feeding Both birds assisted in feeding the young and became very tame, waiting for me to put in their daily feed of termites. The male would go to the nest and feed the brooding female who in turn passed on the ants to the young. Later as the young grew both adults would fill up with ants then regurgitate them to the young. I do not think that the parents fed seed to the chicks until they were about nine days old. As the aviary is a planted one I should say that the old birds caught a lot of live food for themselves. Mixed seed and grit was given as the staple diet, also cattle lick (rock salt) of which all the birds are very fond. The young birds are now self-supporting and the female is already incubating two more eggs in a new nest not far from the old one. 6 A. E. HALL — BREEDING THE BLACK-NECKED STARLING BREEDING THE BLACK-NECKED STARLING (Sturnus nigricollis) j By A. E. Hall (Lower Haselor, Evesham, Worcestershire, England) This species is resident throughout Burma generally, across to southern China and is probably more widespread than this but little seems to have been published about this bird. A hand-reared pair was sent to Mr. W. R. Partridge in March 1967 from Hong Kong by Dr. K. C. Searle. The length of the birds is 11 inches. The bill is black, iris pale buff- white and the legs and feet are pale bluish pink. The elliptical shaped area of bare skin around the eye is yellowish in the adult male and bluish in the adult female. The head, breast, rump and underparts are white, the neck and back is black. A narrow band of white runs across the base of the hind neck and joins up on each side with the white on the breast giving the bird a completely separate black collar. The wings are black with a patch of white flecks on the shoulder, the thumb (false wing or bastard wing) is white with a broken white line running from that point across the tips of the median wing coverts and the secondaries are also tipped with white. The tail is black tipped with a narrow band of white. The white rump is only seen in flight. For a few weeks after arrival they were housed in a large cage in the bird-room and settled down quickly even though their diet was changed slightly. Fruit, in the form of apple and orange with the occasional piece of banana and a few grapes, was taken readily and mealworms were relished. Coarse insectile food and raw minced meat soon formed an equal part of the diet to the fruit as the quantity of mealworms was reduced. Maggots were left and only eaten when other more desirable foods were finished. As the birds settled down, fruit was reduced to just soft, sweet apple. When all signs of hard frost had gone and spring was set in its ways the birds were moved to a planted aviary measuring 22 ft. x 8 ft. with an adjoining shelter of 10 ft. x 8 ft. Since we knew little about the breeding habits of these birds they were furnished with a hollow log hung about 7 ft. from the ground as well as there being many possible nest sites in the bushes. In the summer of 1967 they chose a site on top of the nest- log and began building a large untidy nest, mostly of dead grasses from the aviary floor and hay which was supplied to them. Eggs were laid, incubated, and hatched but the chicks were lost in the early stages of rearing. The birds remained in the aviary throughout the winter and in the summer of 1968 began to build once again. This time they chose a site on a wire platform in the corner of the aviary and everything went well until the chicks were about a fortnight old when unfortunately they were lost once again. A. E. HALL — BREEDING THE BLACK-NECKED STARLING 7 In 1969 they seemed to start in a haphazard manner, carrying nesting material to many possible sites, then quite suddenly after two weeks of this undecidedness they chose an entirely new site about 6 ft. from the ground in an elder bush, and had completed the nest in three days. On the 23rd May I noticed during feeding that only the cock was visible and this continued until 28th May when the hen appeared. The nest contained five eggs and this was the only time that I saw the hen off the nest during incubation. The first sign of anything happening came on 10th June when I saw the shell of a hatched egg on the ground. Maggots were fed ad-lib. and on 12th June another shell appeared plus the sounds of chicks in the nest. The consumption of maggots began rising and after the first few days a small quantity of mealworms were supplied also. The amount of live-food being utilized by the birds reached a peak of one and a half pints of maggots and a handful of mealworms daily on 22nd June, then remained constant for five days before starting to reduce. Nest inspection on 28th June revealed only one chick, quite well feathered, and the remains of a chick which must have died a few days earlier. The parent birds were living almost entirely on live food themselves because the amount of minced meat and apple being taken was negligible. On 1 st July the chick was sitting on the edge of the nest entrance and two days later it had left the nest completely and was hopping about on the ground and lower branches of the bushes. After seeing the chick out in the open I realized that its legs were twisted and splayed as if due to calcium deficiency. This chick died a few days later and the parents very quickly began building again but due to the overgrown state of the bushes I did not know where. Again the hen was lost from view and on 30th July, after seeing both birds out in the open, I inspected the old nest to find that it had been renovated and contained partly incubated eggs. An empty shell appeared on 4th August and again maggots were fed ad-lib., but this time with additions to try to overcome the deficiencies of the chick which was lost earlier. To one pint of maggots I added one teaspoon of “ Stress ” calcium and phosphorous powder, one teaspoon of Gevral protein food and one c.c. of “Abidec ” multi-vitamin. The birds took to this quite readily and an ad-lib. supply continued until consumption reached one pint daily then they were restricted to this amount. Minced meat was increased to meet the demand and a few mealworms, pupae and beetles were given also. On 22nd August a few maggots were left over from the day before, previous to this everything had been eaten and food-pots were strewn everywhere in the search for live food. Three days later a chick was sitting on a branch just outside the nest and over the next few days it ventured further afield. This youngster appeared quite strong and showed no signs of any outward deformities, then on 29th August it was found dead. For the first time I saw two more chicks in the seclusion of the elder bush so every attempt had to be made to save them. 8 A. E. HALL — BREEDING THE BLACK-NECKED STARLING A quick post-mortem revealed that suffocation due to gape worms could have been the cause of death, everything else appearing to be normal and the bird in excellent condition bodily. “ Thibenzole ” powder was mixed into a solution with water following instructions on the packet and given at the rate of i c.c. per lb. body weight. The dead chick weighed 4 ozs. and I estimated each parent to be about 6 ozs., then put i J c.c. of the solution on the maggots, rather than risk possible losses from catching to give direct dosage to each bird. This treatment was omitted for a day then given again the following day and once a week thereafter as a precaution. The juvenile plumage is greyish fawn and brownish black with rather indistinct borders between the two colours. Adult plumage is attained in the first moult. After the chicks had been out of the nest for three weeks I had to transfer them to another aviary because the adult hen was driving them around in an unsociable manner. The youngsters, now on their own, feed entirely on raw minced meat, leaving the maggots, both with and without the additives mentioned earlier, untouched. By the end of October they had completed their first moult and now look exactly like their parents. The adult birds made another attempt at breeding after the youngsters had been removed but gave up after two eggs had been laid. I examined the nest and found it approximately 18 in. in diameter and of the cross section shown. The egg measurements were i J in. x J in. and of a light turquoise blue colour. As described above A. E. Hall has bred the Black-necked Starling Sturnus nigricollis. It is believed that this may be a first success. Any member or reader knowing of a previous breeding of this species in Great Britain or Northern Ireland is requested to communicate at once with the Hon. Secretary. F. MEADEN — NOTES ON BREEDING 9 NOTES ON BREEDING THE COMMON WHITE- THROAT, NUTHATCH, WILLOW WARBLER AND WAXWING By F. Meaden (Cheshunt, Hertfordshire, England) I have, for many years, been keeping birds of British and European species, trying to discover the conditions and diet which will keep them in good health in aviaries and induce them to breed. The birds described here were kept in a suburban garden at Slough, where the aviaries, at first at the bottom of the garden, gradually spread over a large part of it. In order to check what was happening I kept a record of the various nestings on large cards which could be filed to form a permanent record. The following account gives details of some of the breeding achieved. Since it is difficult to discover with certainty which of these species have, or have not, been bred in aviaries I had not attached very great importance to these, with the possible exception of the Waxwings; but the Assistant Editor informs me that there appear to be no adequate published records of the breeding of these particular species, and has asked me to prepare these notes on them. COMMON WHITETHROATS A pair of Common Whitethroats, Sylvia communis , after spending the winter of 1953 in an unheated birdroom were, in early April 1954, given the freedom of an 8 ft. x 3 ft. x 7 ft. outdoor aviary built alongside the garden fence on what had previously been a flowei bed. The roof, although of wire, was almost covered by polythene sheet, the rear along one of the 8 ft. sides was overgrown with hops, and one end was shut off completely by a dense lilac bush, which also sent up a host of shoots through the earth of the aviary floor. The end portion where the lilac branches encroached into the enclosure was packed with gorse to a height of about two or three feet and this, with a blackberry bush growing in its midst, the lilac and hops all contributed to provide quite a dense growth. The remainder of the enclosure was fairly clear except for a turf or two of grass, a small wood ants’ nest and the birds’ bathing facilities. On 14th April the birds were seen carrying some small white feathers into the gorse. After throwing down a few mealworms at the opposite end of their aviary to keep the birds occupied, we removed a ply- wood sheet which hid an observation hole into the bush. We found that a nest was almost completed. When we provided a wad of dog hair they showed no further interest in feathers and lined the nest fully with the latter material. On 17th April the first egg appeared and four more were laid on consecutive days. Three young had hatched by 5th May and we noticed a sudden change in the parent birds’ food consumption; little fruit was now taken but the Farex and maggot intake was doubled, and IO F. MEADEN — NOTES ON BREEDING mealworms were cleared from the dish directly they were given. Whether ants were taken I do not know, there were however no eggs at that time. The hops which covered the side of this aviary were absolutely smothered with greenfly, the back of each leaf being thick with them. These too must have formed a large part of the nestlings’ diet because the parents were often seen working the vine-like stems. The pear so avidly taken prior to rearing was left almost untouched but by 25th May the soft pulp of the fruit was once again taken and only the hollowed-out skin remaining. Previous to 28th May only two young had been seen moving around the aviary, but on that day we observed three and the two adults. One youngster seemed very large but two were far smaller. Even so all were seen to be taking grated cheese, Farex, pear, grated carrot, maggots, greenfly and even the soft food and mealworms. The old hen died suddenly on 7th June. She appeared perfectly fit in the morning but was dead at 6.30 p.m. The young and the adult male were all in excellent condition. The young were now also taking soaked household currants, a favourite with many warblers. With Autumn the four remaining birds fed almost exclusively on ripe elderberries. The amount of weight which was now put on was amazing and there was now little if any disparity in size or weight of any of the birds. NUTHATCHES A pair of Nuthatches, Sitta europaea , were given me by a friend in the autumn of 1954. They were overwintered in a large aviary with a number of other species, but made themselves a nuisance by stealing the sunflower seeds intended for the finches, however great the quantity, and concealing them in crevices and in the ground at the foot of wooden supports. They were therefore moved to another aviary, an all-wire structure of irregular shape, about 9 ft. x 6 ft., which they shared with a pair of Reed Buntings Emberiza schoeniclus. A major part of the aviary was occupied by a pond 6 ft. x 3 ft. with a lot of water iris. The aviary was built around the trunk of an old, 30-foot apple tree, the enclosed part of the trunk being covered with honeysuckle and having a “ V ” shaped fork into which a nest-box was secured. The box was of a horizontal type, made of wood and covered with bark, and with one side fitted so that it could be removed. Maggots, mealworms, grated cheese, beetles, earwigs, a marrow bone, suet, soaked sunflower seed and Avi-vite soft food was the standard diet, and in addition either the Reed Buntings or Nuthatches were taking tadpoles and small frogs from the pond, for on a ledge of the aviary were the remains of dozens of these creatures. During the season the Reed Buntings tried to nest, building low in a gorse bush, but the Nuthatches destroyed four nests of eggs, which I took to be sheer vandalism on their part. Friends had visited us one Sunday in June 1955, one intending to take some photographs of the birds, the other merely to see the collection. We were all relaxing in the sun when F. MEADEN — NOTES ON BREEDING II one called out, “ Do you know your Nuthatches are feeding young? ” My immediate thought was that, as was their customary habit, these birds were carrying up and hiding food. However, when I investigated the box to prove that he was wrong I found four strong youngsters with feathers just breaking through. The parents continued to rear them on the diet provided without difficulty. In the autumn bickering between the birds had commened in earnest and since space was short we decided that the Nuthatches had to go. We had at that time a flat near Kensington Gardens and thought that this would be an ideal spot. We housed the birds separately for the winter, having sexed them as three definite pairs, and in April 1956 we liberated the old pair and one of the young pairs. They were released very close to Bays water Road, nearly opposite Lancaster Gate Church. An interval of 25 minutes was allowed between releasing the pairs, and in each case they remained within a few feet of each other, climbing the trees as though they had known the place for years. We chose this area mainly for sentimental reasons, having spent many leisure hours watching the park’s birds. The releasing of these birds had a rather unexpected conclusion. In the London Evening News there appeared later a report entitled “ Rare birds back in Royal Park after 50 years ” and referring to the nuthatches. We notified organizations which would be interested of the part we had played in this new sighting. This resulted in correspondence between the Nature Conservancy and ourselves, clearing up the matter. However, it is nice to know that the birds did breed at a later date. WILLOW WARBLERS An adult pair of Willow Warblers, Phylloscopus trochilus , were given me in the autumn of 1959 by an old friend, Mr. R. C. Tout. I kept them over winter in an unheated birdroom and put them out in spring into one of the aviaries along the side of the garden. This structure was 8 ft. x 7 ft. x 3 ft. The rear was covered by hops and convolvolus, at one end a wisteria completely hid 2 ft. of the structure, while at the other end and over a fair amount of the aviary front was a well-grown grape-vine. Inside the aviary grew Everlasting Pea. With all this cover observation was not easy, but on 3rd June i960 we noticed that there were more birds in their enclosure than there should have been. After watching for the best part of an hour we found that at least three young were being fed by the old pair. Further examination of the aviary from the inside revealed a nest low down in an old dead fir which was overgrown with convolvulus. The adult pair, normally so tame, were now behaving like mad things, calling frantically and keeping as far as possible from me. One youngster had joined them and the other two went to ground. For fear of treading on them I had to retieat from their enclosure. 12 F. MEADEN — NOTES ON BREEDING The fouled and used nest was composed of grasses, honeysuckle skin from branches growing in the aviary, what appeared to be old leaves of iris, and the lining was of hair and feathers. They must have worked really hard to gather all these items, for I had provided no nest material, being under the impression that both had sung and that they were two birds of the same sex. Two young were of the same size as the parents but the third was a weakling. From the nest I recovered the body of a fourth chick so dried into the hair and feathers that no age could be assessed from the remains. From this data it would seem that they must have nested about the first week in May. In the enclosure was a nest of wood ants acquired from a nearby beechwood and a bamboo cane pushed through the wire netting, inserted into the anthill, and moved from side to side, uncovered many pupae daily. They were small but were avidly taken. It was noticed that if an ant got onto a bird’s leg the bird would peck at it in fear and fly off. All the climbing plant growth within the aviary produced much greenfly and a profusion of mixed insect life. We saw the adults feeding the young on greenfly, but since the maggot dish was emptied more quickly than usual I imagine that these too were being taken for them. What had first caught our notice was the male actually regurgitating a sort of white liquid. It was probably only Farex but the regurgitation surprised me. The food prior to the young being observed had been grated cheese, Avi-vite softfood, wax-moth larvae (normally only given at week-ends when time permitted), ripe pear, fruit fly which they took on the wing or from a bucket containing over-ripe fruit, and Farex to which we added calcium phosphate during the breeding season. Our only addition now was a handful of mealworms in a dish at their late afternoon feed, together with increased quantities of the other foods. According to my record card, on 6th June all the young were thriving and searching for insects through the aviary vegetation. One male was rather bare about the head, and the adult male was seen to attack it when it ventured close to him or the female, whether because it was a male or because of its begging for food I do not know. The runt of the three had now improved, and although still a shade smaller in size was as strong on the leg and wing as the others. A number of people saw the young, but none were more surprised than I by the successful rearing of them. Had I even suspected that they were a true pair at the start, or that some attempt to nest and breed was being made, I would certainly have gone to a lot of trouble to assist; but I feel certain that the abundant supply of greenfly weighed the balance in their favour. WAXWINGS I had kept a number of Waxwings, Bomhycilla garrulus , for some years, but although I had successful hatchings in previous years it was not until 1962 that the young were actually reared. I published some notes on F. MEADEN — NOTES ON BREEDING *3 breeding these birds in the magazine (Meaden 1964) but did not give the actual nesting account. The flock of a dozen or so birds was kept in a fairly large aviary with overall dimensions about 30 ft. x 14 ft. x 7 ft. They were sociable birds and even in the breeding season would rest within inches of each other, the males showing no territorial aggression even when nesting unless an interloper actually alighted at the nest, when the reaction was limited to a forward threat with widely gaping mouth. The flock was not made up of equal pairs. Females predominated in a ratio of about two to one. The breeding displays have been described elsewhere (Meaden 1964; Meaden and Harrison 1965). It was in June that our birds started nesting. As usual dried chickweed and grasses formed the basis of the nest, some birds using home-made nest-baskets, others using natural twigs. All the nests were lined with animal hair or fur, and with vegetable down from seed-heads. There were at one time seven nests in use, the two closest being about 9 in. apart at the most, while one of the lowest I have known was about 3 \ ft. off the floor. Most were under some sort of overhead cover. The enclosure had a small apex roof covering a through path and two nest were built up under the corrugated plastic roof; while others were under a felted i-ft. wide sheltered portion around the perimeter of the aviary roof. Apart from this proximity to overhead cover, the nests themselves were in relatively open sites. The hens all went to nest within a few days of each other, the first seeming to trigger off the impulse in the others ; although courtship display had been witnessed since early spring and the displays had increased in frequency until one could hardly ever look into the enclosure without seeing some birds displaying. In addition to being highly sociable among themselves these birds were very tame, although all these northern species seem to be highly tractable. I found that if, when a hen was brooding, I moved a finger towards the tip of hei bill and then quickly drew it back, she would tend to snap at it. I took advantage of this behaviour and after concentrating for a few days on the hen which appeared to be the most co-operative I had her snapping a mealworm, maggot, waxmoth larva, sowthistle head or even a small blob of Farex from my fingertip. I carried on with this procedure until she readily took whatever was offered. The females were normally fed by the male when incubating and in the early stages when the young were in the nest, and to some extent this taking of food from my fingers might have been an extension of this behaviour. This female was one of the earliest to go down, and the chicks hatched on 14th June after an incubation period of approximately 14 days. I usually take an annual holiday at this period of the breeding season and luckily, on the day the young hatched, a good supply of fresh wood ant pupae had been collected from a nearby locality. Although a few pupae had been given prior to this, we were now able to offer dishes of them, and in addition the co-operative hen was continually offered them while H F. MEADEN — NOTES ON BREEDING she sat on the nest. I cannot recall ever seeing her off the nest while with eggs or small young, though she might have left it during my absences from the aviary. Now, with newly-hatched young, immedi¬ ately we fed her with ant pupae, waxmoth larvae, or Farex she would raise herself up, reach down and feed the chicks. Since on the day this first happened I had been able to check earlier that only two of the eggs were hatched some of this food may have provided their first meal. At this time we had started to use a high protein invalid food, Casilan, of which a friend had given me a little and which we sprinkled on maggots and mealworms, and now also on the food offered to the Waxwings. We continued to feed this bird on the nest frequently and this extra food, in addition to that brought by the male, was probably critical in that the young of this brood survived to fledge while others did not. In other years we had lost the young, apparently because they were choked by soaked currants given them by the adults. With the hatching of these young I was anxious to prevent this happening again without suddenly removing a major part of the food supply and possibly impairing the fitness of the birds or causing discomfort to those not nesting. We finally decided to mince the currants so that even if they were fed to the young they would not choke them. We found, however, that the intake of currants stopped drastically in any case at this period, and since apple was still available in quantity and since all the birds were now taking ant pupae in addition to the usual basic diet there was little harm in stopping the supply of currants for a short while. In the nest where the hen had extra food four young hatched but only three were reared. The young in other nests reached varying stages up to five days and I feel that the losses were probably due to the impossi¬ bility of providing sufficient live food of the ant pupae type for a flock of 12 adults and three or four broods of young all requiring it at once, with the result that each only received a limited supply. The male was not seen to feed the young directly until they were seven or eight days old. The three young fledged at about a fortnight, at the beginning of July. About two months later they began to moult into adult plumage. In doing so they went into a very heavy moult. I wondered whether this was due to the relatively warm weather. Waxwings seem to suffer from the heat and I had noticed that the incubating females would sit with open bills, or rise slightly on the nest in apparent discomfort on warm days. The young ones moulted so heavily that they could not fly up to their usual roost perches and therefore roosted in a more open part of the aviary. They became saturated and chilled during a very heavy rainstorm and two subsequently died, only the one surviving through to full adulthood. There is a great deal of nonsense written about this species, including recommending as a staple diet food such as bread and milk, which might help as an addition but which is otherwise a poor diet item, or the with¬ holding of some normal foods such as fruits for fear they might stain the F. MEADEN - NOTES ON BREEDING !5 plumage; while writers without breeding experience solemnly recommend only one pair to an aviary. Some of our birds had been with us for 13 years when they were stolen and one must have been 15 years old since it was fully adult when it first came. I am certain from my experience that this is one of the simpler birds to keep healthy and in a wonderful plumage. As regards the diet, I would still recommend the foods I mentioned in the previous article — i.e. soaked household currants (strained before use), grated carrot, greenfood such as brassicas, spinach, watercress, comfrey, dandelion or similar plants, Farex mixed with milk, softfood, small quantities of grated Cheddar cheese, together with an occasional pinch of calcium phosphate and a few drops of multivitamin. This together with plenty of sweet apple. A dish of maggots and similar live food is necessary at some times of year; but in my experience the Waxwings almost completely dispense with live food in winter, unless the diet is deficient in other respects, in which case they may take all kinds of exceptional foods. Their intake of live food rises to a peak in July and August when they would be feeding young. Berries of Mountain Ash, Elderberry, Blackberry, Berberis and other berries are very valuable parts of the diet when in season. We give Sowthistle with seedheads which are pulled off and swallowed whole, the base going first and the downy end disappearing down the throat last. This does not seem exceptional since they are said to take similar soft, ripe seedheads in the wilds. I am doubtful about keeping them with seedeaters that require hemp in the diet since the Waxwings will remove and eat these seeds immediately, and I am not sure that the cumulative effect may not be harmful and overfattening.

HOLYOAK — OBSERVATIONS ON A PAIR OF GREEN BROADBILLS 5 OBSERVATIONS ON THE BEHAVIOUR OF A PAIR OF GREEN BROADBILLS ( Calyptomena viridis) ,1 By David Holyoak (London, England) During April and May 1969 I made brief notes on the behaviour of a pair of captive Green Broadbills ( Calyptomena viridis) whilst studying other birds at the London Zoo. Virtually nothing has been published regarding the calls and behaviour of this species, so it seems worth recording these observations. The Green Broadbill is a plump, short-tailed bird, rather larger than a Starling, from the forests of Borneo. The plumage is emerald green throughout in the female, with black wing-bars and a black spot behind the eye in the male bird. The bill is partly hidden by stiff feathers growing from the base. These observations were made on a male and a female kept in a cage about 5 ft. x 8 ft. x 12 ft. high with several growing plants and numerous perches, in a large heated room.. Even for captive birds they were rather lethargic, remaining perched except for infrequent bursts of fast whirring flight, and visits to food trays on the cage floor. Both birds have been heard to give a variety of high-pitched piping calls, sounding variously like kweea varying to kwee-weer\ and a high tui-tor call. These notes were given in a wide variety of circumstances, and some of them probably function as contact calls. A distinctive, soft, but penetrating, kwoi kwoi kwoi call, repeated about five to ten times, was often given by both birds; the head of the calling bird being bobbed in time with each note. This is probably an alarm call, as it was most often given when I was very close to the wires of the cage, and when the wires were rattled. The flight intention movements have two components common in passerines, a quick upward flick of the wing- tips in which they are lifted up to a centimetre or so, and at higher intensity, a quick crouching movement. The appearance of these birds can change abruptly as they fluff or sleek their plumage, but besides the fact that the female often fluffed as a response to slight aggression from the male, and when soliciting copulation, it was not possible to investigate this with a single captive pair. Copulation was seen twice, and the associated behaviour was similar each time. First the male hopped towards the female and perched on a branch near to, and facing her. He then gaped widely two or three times, bending the upper mandible back to a remarkable extent and exposing the bright orange-pink interior of the bill. Before the gaping movements and interspersed with them the head was tilted back away from the female with the neck feathers fluffed. On both occasions the D.

Both birds have been seen to make the wide gaping movement at other times (the female also has a bright orange-pink inside to the bill) when mating did not follow. The male bird has been watched regurgitating food and then swallowing it again, and once the female hopped towards him as if expecting to be fed, but I have not seen courtship-feeding take place. I am grateful to Dr. Peter Olney, the Curator of Birds at Regent’s Park, for affording me facilities to study the birds in the collection, and to Clifford Frith and Colin Harrison for drawing the display postures. # B 1 8 S. T. JOHNSTONE — KEEPING AND BREEDING FLAMINGOS AT SLIMBRIDGE KEEPING AND BREEDING FLAMINGOS AT SLIMBRIDGE By S. T. Johnstone (The Wildfowl Trust, Slimbridge, Gloucestershire, England) Although the Wildfowl Trust started in 1946, it was not until 1961 that we obtained our first Flamingos. These were 12 Chilean, followed by more Chilean the same year, and later by a consignment of Greater and Lesser Flamingos from Kenya. In the case of the Chileans, these had been bought from dealers in Holland and had arrived each with the legs folded in a flour bag. Of course, the journey was very short and the birds appeared to be in excellent condition. Unfortunately, the con¬ signment of Greaters and Lessers from Kenya had travelled in crates, in which they were in a standing position. The divisions in which each bird was put consisted of rather rough sacking. They had rubbed their hocks on this sacking and, as a result, the abrasions so caused had become infected. This appeared to effect the Lesser Flamingos more so than the Greater and we had considerable losses in the former. Infection of the joints of the legs of Flamingos would seem to be a most difficult condition to deal with. Of the antibiotics used Chloromycetin was the most success¬ ful in effecting a cure, but experience shows that great care must be exercised in the design of the travelling crates. Caribbean Flamingos were not obtained until the following year, when Antwerp Zoo very generously presented us with a pair. Subsequently these were added to by birds purchased from Florida. In 1965, we obtained our first Andean and James’s Flamingos from Mr. Cordier. Flamingos are related to wildfowl, but I am afraid our knowledge of their husbandry and their feeding habits, etc., was not our strong point, and, having decided that these birds should be added to our collection, it was imperative that we increased our “ know-how ” as to keeping them. So whilst collecting the various forms we were, at the same time, visiting experts in the Zoos seeking their advice, not only as to how the birds should be fed, but also how to retain their colour and how they should be kept in winter. The information obtained from the principal collections both in Europe and America varied a great deal but from it we have developed our own method of keeping the birds, of providing adequate nesting sites, and of the way in which they should be fed. The collection now consists of some 225 birds. 37 Rosy, 74 Chilean, 20 Andean, 50 Lessers, 30 Greaters and 14 James’s. In order to facilitate their breeding, we designed and built Flamingo atolls, this involved a considerable amount of work. The draining of the ponds and then building up with hard-core and rubble two banana shape ridges, leaving at the ends an opening between them. The rubble was covered with concrete smoothed down and at an angle of 30 degrees to the bottom of the ponds. Between the ridges was then filled with Avicult. Mag, Copyright ] Andean Flamingo with chick [Philippa Scott S. T. JOHNSTONE — KEEPING AND BREEDING FLAMINGOS AT SLIMBRIDGE 1 9 mud and sea sand, a small entrance at each end left so that water could flow in and keep the mixture of mud and sand at the right consistency for the Flamingos to build their mounds. Encouragement was offered them in the form of concrete replicas of nests, several built close together at one end of the island. It was not until 1967 that any nest building activity was apparent. In this year the Rosy Flamingos built a number of nests. They even planted a little mud on some of the concrete replicas. There was slight activity amongst the Chilean Flamingos as well, but no eggs were laid. However, in May 1968 the activity amongst the Caribbean Flamingos was such that in a relatively short time some 16 nests were built. In the middle of May, two eggs were laid on successive days. One must explain that the pen where the Caribbean Flamingos are kept is overlooked by our Restaurant and tea terrace, which is separated from the sward of the pen by a low stone wall. Although a fairly continuous watch was kept to see that visitors did not enter the pen and disturb the two sitting Flamingos, one person we had forgotten about, and, one day, when no member of the Staff was near, the window cleaner arrived to clean the outside of the restaurant windows. He went over the wall with his ladders and imme¬ diately the incubating Flamingos left their nests. Fortunately a visitor realized something was wrong and came for a member of the Staff. The window cleaner immediately left the pen and the birds came back to their island but one of the two birds at once rejected the egg from its nest, whilst the other one sat down quite comfortably. The rejected egg was replaced, but the flamingo again rolled it out. It was thought that if we continued to return the egg we would cause the second bird to do likewise, therefore one more attempt was made with a wooden egg and the rejected egg was placed in an incubator. Likewise the wooden egg was rolled out. On the 14th June, slight tapping and squeaking was heard from the egg in the incubator. We decided that the possibility of rearing a young freshly hatched flamingo was beyond us. We could not reproduce the regurgitated food with which the parents feed the young. The remaining egg, that was being incubated by the parent, was therefore examined and found to be infertile. It was exchanged for the live egg and within 24 hours the first flamingo to be hatched in Britain made its appearance. The hatching was followed by foul weather for about a fortnight and one saw the chick on occasions almost covered in mud. It did not leave the nest during this time and was first seen out of the nest on the fifteenth day. Both birds shared brooding and both birds fed the young one at frequent intervals of about 20 minutes; the male taking the major share of this work. After 17 days, the downy young was seen to be attempting to feed itself although its main sustenance came from its parents. This was continued until the bird was almost fully grown and it was seen that the parent birds were gradually loosing their bright pink coloration. The young one was removed and put in with our James’s Flamingos for a 20 S. T. JOHNSTONE — KEEPING AND BREEDING FLAMINGOS AT SLIMBRIDGE period of about a month. After this, on account of it seeming not to be very happy in its new surroundings, we returned it to the main Caribbean flock. On its return, the parents, or foster parents as they really were, showed no further interest and junior fended for itself. After a year its plumage is bright pink and, if it were not for the fact that its legs are grey and its hocks black, it would be indistinguishable from the other members of the flock. Our Andean Flamingos, of which there are 20, live in a small pen compared with those of the other flamingos at Slimbridge and are very close to the public. The only place where we could build their atoll was within some three or four yards of the main pathway. Here, this year, they built nine nests and seven birds laid eggs. We were highly excited as this was the first time that this species had produced eggs in captivity and we had high hopes of hatching the first Andean Flamingo chick. But as the termination of the incubation period of each egg occurred there was no sign of hatching. By this time we had just about given up hope and decided that the reason for the failure to hatch was that the birds were pinioned and could not balance themselves for proper copula¬ tion, but on examination, five of the eggs were found to be fertile. Then to our great joy the seventh egg hatched on the 29th day of incubation. The chick behaved quite differently from the Caribbean Flamingo. It happened to fall out of the nest on the day it hatched and it crawled back in, but on the second day it left the nest of its own volition and after a very short time it did not bother to return except at night. It is now well grown, its legs are black and the bill shows no sign of yellow as yet although the wings are quite pink. Whilst this activity was going on with the Andean Flamingos, our flock of over 70 Chilean started a major nest-building campaign. Some 50 odd nests were built and at least 30 eggs laid, from which 10 young birds have hatched. As in the case of the Andean, some chicks left the nest after the second day and scarcely ever returned, except to be brooded by the parent. The Rosy Flamingos showed two separate nest-building activities and we are sorry to say that on neither of these occasions did the birds lay. Whether flamingos lay every year one has not been able to ascertain. One suggestion for the failure to lay this year has been that the young should be removed from the flock or the birds will not re-nest the following year. This, one feels, has yet to be proved. A difficulty we have experienced is the wintering of the flamingos, in particular, the Lessers and Caribbean. The weather at Slimbridge is far too bleak to leave these birds out, so we have developed a building where they can be housed, and at the same time, where they can be seen during the winter months by the visiting public. These consist of rectangular wooden sheds some 50-60 ft. long by 20 ft. wide — one side of which contains a number of windows, not only to give light to the birds, but also HARRY FRAUCA — THE AUSTRALIAN PENGUIN 21 to allow the public to see them. The houses are built over a water course so that the water is constantly flowing through the buildings and over the waterway is a large door through which the flamingos can be walked into an adjoining pen where, if the weather is sufficiently bright and sunny, they can spend a little time outside. The water runs close to the window side of the building and represents about a third of the width. The other part is a gently sloping concrete surface which is trowelled over and then painted with a rubberized paint to prevent damage to the feet of the birds. Infra red lamps and strip lighting are provided. Considerable trouble has been taken regarding the diet of our birds and various forms have been tried. Finally, the following meal is made by milling together equal quantities of wheat, dried shrimp, maize, poultry biscuit and turkey starter crumbs. To this is added minced lettuce, carrot and beetroot. The whole is then mixed with water con¬ taining Canthaxanthin, Rodophyll and Tylan, into a soup-like consistency. The soup is fed twice a day. THE AUSTRALIAN PENGUIN ( Eudyptula minor) By Harry Frauca (Canberra, Australia) Although penguins are associated with ice floes and the barren wastes of the Antarctic, some species never see a chunk of ice in their lives and among these the Australian fairy or little penguin, Eudyptula minor , is an interesting example. An attractive bird standing about 18 in. tall, it has dark blue dorsal plumage and silvery white breast. Like all penguins it is totally flightless, its wings being modified for paddling and swimming. It walks in an upright posture and its appearance, antics and general demeanour captivate anyone who has the good fortune to encounter it. There is no difficulty in finding this penguin. There are thriving colonies of the species on Phillip Island, just a short distance from Melbourne, on most Bass Strait Islands and all along the coasts of Tas¬ mania. Others are encountered in different parts of coastal southern Australia with an occasional straggler reaching Moreton Bay, in south Queensland. Phillip Island, the Bass Strait islands and Tasmania carry the largest colonies of this species. In Tasmania, the little penguin appears not to mind humans at all and may live in the suburbs of Hobart undisturbed. The well-known Tasmanian ornithologist-author Mr. Michael Sharland has recorded fairy penguins breeding “ under boatsheds along the Hobart waterfront. It is a noisy bird and often disturbs people living close to the water ”. 22 HARRY FRAUCA — THE AUSTRALIAN PENGUIN The Fairy penguin never goes south and although its movements are not known, its daily routine has been observed frequently. Usually, the bird (in parties varying in numbers) spends the day swimming and feeding on aquatic animals and plants with occasional resting spells on rocks or sand-bars. On many occasions, during my years in Tasmania, we passed rocks half-awash in the sea each crowded with a multitude of penguins taking a rest. There is probably no other bird that can be watched more easily or at closer quarters. In fact, you can have too much of its some¬ times. During my student days in Tasmania, we would often go to spend the night at the penguin rookery on Bruny Island, off the east coast of the island State, an experience that is unforgettable. The best time for observations is during the breeding season which extends between August and March but appears to reach its climax around October-November, depending on the year. The penguin rookery is situated on the isthmus linking north and south Bruny and consists of several high sand dunes rising a couple of hundred feet partly covered with tussock grass. On the western side of the rookery there is a road with a notice that reads “ Penguins cross here, drive carefully ”, Beyond the road there is the D’Entrecasteaux Channel and beyond this the coast of Tasmania. On the eastern side the dunes slope down to a wide desolate beach and to the Southern Ocean often bleak and stormy-looking. Life on the rookery during the day is quiet and peaceful, lulled by the sounds of the surf and the occasional call of a sea biid. Motor traffic on the road is rare to say the least. There is not a single penguin to be seen and you wonder if you are really in a rookery of this species at all. The penguins are there, right enough. They are in the countless burrows excavated in the sand, some visible to the naked eye, others concealed by the tussock grass. At this time of the year, the birds are brooding their eggs, which are spotless white. A hen penguin may lay one or two or even three eggs, but there is evidence that one or two form the average clutch. The burrow varies in depth from about 2 ft. to 3 ft. with the entrance hole about 6-7 ins. in diameter. The penguin can be very pugnacious at all times but more so if disturbed in the burrow during the incubation period. On many occasions, in order to inspect the bird and the clutch or the parent and the young, we would thrust an arm into the burrow, an action which caused the adult bird to emit a series of calls and hammer the hand savagely with its strong bill. Because of this we had to protect our hands either with gloves or with socks padded with grass. The fairy penguin is one of the strongest little wild creatures I have known. As you hold one in your hands you cannot help wondering at the toughness and compactness of its body. It is a solid mass of muscle with a thick coat of fat (between the feather covering and the skin) which forms an insulating layer. The feathers are Avicult. Mag Copyright ] [Australian Information Service Fairy Penguin and chick in burrow. Avicult. Mag. Fairy Penguins returning to the nest, Phillips Island, Victoria. HARRY FRAUCA — THE AUSTRALIAN PENGUIN 23 so short and compact that they look as though the bird was covered with a skin rather than with an ordinary plumage coat. In conversation with some ornithologists I was told that many fairy penguins at the Bruny rookery — and in others — appear not to make the burrows but to appropriate burrows excavated and abandoned by the short-tailed shearwater or mutton-bird. Puffinus tenuirostris. This is possible because the mutton-bird, after breeding in Tasmania, departs on its fantastic long-distance movement to northern Japan, Alaska and back to Tasmania again the next breeding season. Thus, if the fairy penguins become in breeding condition while the mutton-birds are travelling, they can appropriate empty mutton-bird burrows without finding any opposi¬ tion. On several occasions, we found the Bruny rookery containing brooding penguins occupied the lower burrows while the mutton-birds occupied the ones closer to the top of the dunes. One of the most interesting scenes to be seen in Australia is the penguin parade on Phillip Island when, at dusk, parties of penguins swim ashore and cross the beaches to the delight of tourists. But few people have seen the penguin parade at Bruny Island. I am lucky to have. After dusk, during the breeding season, dozens of penguins that had spent the day at sea, swam ashore in parties of four or five or a dozen with an occasional solitary bird. On landing each penguin would stand in the sand and shake itself vigorously. Hundreds of them lined the beach at the water mark, their bodies glistening in our spotlights. The noise they made cannot be described in words. Their calls rose high above the pounding of the surf and the wind and mingled with the calls of the birds that had stayed in the burrows. The result was such a terriffic din, such a fantastic pandemonium, such an extraordinary intensity of vocal sounds that you seemed to be in a mad world. Nobody could forget that experience. Calling intermittently, the newly-arrived penguins would make for the burrows, waddling across the beach, scaling the sand dunes, pushing their way through tussocks of grass. Some strayed into our tents from where they had to be shooed away in no uncertain terms. The function of the sounds, however, was clear enough. They served for communication so that each newly-arrived bird eventually reunited with its partner that had been left behind to incubate the eggs. The two birds would stand side by side in front of the burrow in a typical “ nest- relief ceremony ”. They would call softly as though whispering to each other and bow and touch each other before the two would enter the burrow. Once the pairs had reunited and retired inside the burrow, a profound silence fell on the rockery. The sounds of the sea and the wind were all you could hear. The silence did not last long though, for around dawn the insane cries would break the stillness. Leaving its partner in the burrow, a penguin would now head back for the sea, calling stridently, and it was then when one of the most amusing scenes in penguinland took place. The penguins 24 J. DELACOUR — THE BIRDS AT CLERES IN 1 969 that had emerged from burrows high on the dunes would slide down the sand slopes on their bellies. It was indeed a quick way of getting down the dunes and there is no doubt that the fairy penguin is an expert at it. Some slid down distances of 40 yards or more and fetched up at the foot of the dunes where they became almost buried in the soft sand. Long before sunrise, the rookery would be silent again, a contingent of penguins incubating the eggs in the burrows, the rest swimming in the Southern Ocean in pursuit of food. So the cycle went on. And to me the memory of those nights in the penguin rookery has remained as one of the most gratifying experiences in my career as a naturalist. Although occasional penguins are shot by fishermen for crayfish bait, they are wholly protected throughout Australia and the thriving rookeries on Bass Strait and Tasmania ensure that we shall have Eudyptula minor with us for many years to come. # * # THE BIRDS AT CLERES IN 1969 By J. Delacour The summer of 1969 has been one of the best I can remember, as far as the weather goes, in Western Europe. But it has not been a good breeding season for birds. The spring was dull and cold and the number of clear eggs high. Certain species even did not lay at all, particularly Waterfowl. I suspect that the exceedingly wet and chilly summer of 1968 is partly to blame for it. Just as a number of plants and shrubs flowered poorly because they had failed to mature their growth properly the previous season, birds never got into good breeding condition. A large number of young birds and animals, however, were reared at Cleres: five Emus, a dozen Rheas, six Black-necked Swans and many ducks and geese, including Ringed Teal and another brood of five Black Brants. But there were only six Emperor Geese, while none of Red¬ breasted or Ross laid at all. By luck, the only hybrid produced was from a male Black Brant and a female Lesser Whitefront (an almost entirely black bird). A brood of Ruddy Ducks did not survive, the six chicks having been carried away by the flow of the running water. We now have two pairs of Trumpeter Swans, sent by the United States Govern¬ ment. The Tasmanian Water Hens raised 18 young, six under a bantam hen. All the others were reared in the park by two pairs, which never inter¬ fered. Five Brush Turkeys came out of a mound, a number of Peafowls, including five green, grew up. Many pheasants and a pair of Naked¬ faced Currasows (Crax fasciolatd) were raised, as well as ten Sonnerats and a few Ceylonese Junglefowl. J. DELACOUR — THE BIRDS AT CLERES IN 1 969 25 A number of new birds were acquired during the last season: pairs of West African Ostriches, Two-wattled Cassowaries and Wattled Cranes, several Hornbills, Victoria and Sclater’s Crowned Pigeons, Great Argus, Ijima Copper Pheasants (a gift from Mr. Ed. Fitzsimmons), White- headed and Ross Touracous, also a number of small tropical birds for the new accommodations which have been built during the last summer; a modern bird gallery in what used to be the drawing-room of the chateau (50 ft. x 25 ft.), destroyed by fire in 1939. There is a dark passage in the middle of the room, 9 ft. wide, with ten cages on each side, seen through windows — 16 small compartments (3 ft. x 3 ft. x 5 ft.) and four larger ones which constitute aviaries. They are all properly heated, ventilated, decorated and planted. The backs slide up and down, and the cages are serviced from back corridors. There are no signs of doors or food and water vessels, which are hidden by rocks, logs and plants and all located at the back. The hidden tops of the cages and the openings into the gallery are covered with very thin wire netting, which we prefer to glass. The collection of small birds in the gallery is varied. There are only one, two or three birds in each of the smaller cages, while the four flights can accommodate up to 70. They consist of Hummingbirds, Sunbirds, Sugarbirds (including Dacni lineata and a Iridophanes pulcherrina ), Mexican Golden-browed Tanagers ( Chlorophonia callophrys ), all the species of American painted Buntings ( Passerina ), Red-breasted Parrot Finches, a pair of small Red-headed Barbets ( Eubucco bourcieri ), a Cock of the Rock, a Blue and White Indian Flycatcher and several Toucanets. The two larger aviaries contain big Tanagers (Scarlet, Black-throated, Mountain, Red- rumped and White-winged Blue), Blue and White Kingfishers, Pittas (Irena’s and Large-billed), Bellbirds, Amethyst Starlings, Bulbuls and Leafbirds, Rosita’s Buntings, Black-headed Sugarbirds, Roulrouls, Silver Chinese Quails, Sand Grouse and a few Waxbills. The two smaller ones are the home of Calliste Tanagers (10 species), Sugarbirds and Sunbirds. Larger aviaries in adjoining halls are inhabited by several species of Toucans, including the Mountain Blue Andigena laminirostris , Barbets, Troupials, Weavers, Whydahs and Starlings. Some of those birds come from the collection of the late Mrs. Milton Erlanger, as are five Knysna Touracous, all reared in her aviaries at Elberon, New Jersey, during the past few years. They were presented to me by her family and they constitute a living memorial to a great bird-lover and a perfect friend. We hope to build in 1970 a large tropical garden aviary where exotic plants and chosen birds will be displayed as they used to be in my green¬ house before 1940. But it will be planned to allow the visitors to walk through. It no doubt will prove to be an outstanding addition to the park. 26 PAUL FARR ANT - BREEDING MITCHELL’S LORIKEET BREEDING MITCHELL’S LORIKEET By Paul Farrant (Trimley St. Mary, Suffolk, England) My pair of Mitchell’s Lorikeets Trichoglossus haematod mitchellii were housed in an aviary io ft. x 6 ft. x 3 ft. I gave them a nest-box 1 ft. square, facing S.E., in the bottom of which I put a thick layer of sawdust. I had obtained the cock bird in August 1968 and in January 1969 I got him a mate. They were in this outside aviary all the winter. I fed them on condensed milk and sponge cakes, also fruit. I tried other things but without success. I do not know when egg-laying occurred. I had decided to exchange these two birds, and one morning at the beginning of May I went into the aviary to catch them for this purpose. Quite by chance I looked into the nest-box and saw there were two eggs in it, so naturally I decided to keep them. The hen did not appear to sit on the eggs except at night, unless it was cold in the day. I think the hot summer helped. About a month later I saw that one egg had hatched, and the other one hatched the following day. I searched in various books to find out what to feed the young on, and decided to stick to the usual diet, but added maggots. I looked into the nest-box every time I fed the parents, which was twice a day. The young were very noisy when being fed. They wTere fed mostly by the cock bird and soon developed into plump youngsters covered in greyish down. One point I found very interesting, the excreta in the nest-box was over to one corner as though it had been moved there, since the nest had appeared dirtier on an earlier examination, and the young birds remained on the clean sawdust the other side. About two months after they were born (this would be about August) two heads appeared at the hole in the nest-box. This happened frequently for about another month and then one bird came out and a few days later the second one. By this time they were fully feathered and more or less identical with their parents both in colour and size. They are now four months old and are flying around with their parents and feeding themselves on the same diet of condensed milk and sponge cakes. When the youngsters first emerged their beaks were black, but they are now nearly the same colour as those of the parents. I was very surprised to find these birds much less timid than I had been led to believe. M. L. JONES — SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS 27 SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS By Marvin L. Jones (Oakland, California, U.S.A.) My visit to Australia took place in mid-June 1969, with very little forewarning, as my R & R tour from Vietman. I spent six days in the land “ down-under ” visiting the zoos in Adelaide, Melbourne and Sydney, plus the Sir Colin Mackenzie Sanctuary in Healesville. This article devotes itself only to the bird collections in those parks visited. Unfortunately there was not sufficient time to visit any of the many private aviaries or even time to notify these people that I was in the country, much to my great regret. Hopefully on my next visit I can be more leisurely and see all of the zoos and many of the excellent private collections as well. Birds are of course one of the most cared for parts of any animal collec¬ tion in Australia due to the total, complete ban on import of all species that we would call exotic. This ban has been in effect for almost 20 years, thus those specimens of Touraco, Birds of Paradise, exotic Cranes, Macaws, and many others not native to Australia and New Zealand that I saw, were at least 20 years old. Most were far too old to breed. Some were in very poor condition with broken toes and drooping wings, but since each was the last to be seen alive for many years, were cared for like pieces of gold. The Birds of Paradise in Sydney Zoo for instance are in many cases establishing new world longevity records, and the male Ribbon-tail was perhaps the finest I have seen. All came from New Guinea more than 20 years ago to the private collection of Sir Edward Hallstrom, who in turn donated them to Taronga Park, Sydney. They are the last Birds of Paradise alive in Australia. Because of this total ban, zoos and private fanciers are restricted to the show of species that are native to Australia, or which were introduced many years ago and have since become resident, and to New Zealand as well; species that have reproduced well under captive conditions such as certain pheasants, finches, weavers and psittacines; the occasional wild migrant; and of course those still alive that were in zoos at the start of the ban. It has been reported that one zoo in New Zealand recently imported a pair of Mute Swans from Europe, however this has not been substantiated and must not be regarded as a normal experience. All of the zoos that I visited have large programmes under way to breed as many foreign or exotic species as possible, and also those native to Australia. Young from the latter can be used in exchange programmes with zoos outside of Australia and New Zealand not only as credit for purchase of exhibitable mammals and reptiles, but as a means of preventing the large scale smuggling of Australian birds for private fanciers. Hundreds of individuals of rare species, such as the Golden-shouldered Parrot are killed each year in the attempts to take them out of the country to dealers 28 M. L. JONES — SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS in America and Europe. This species is very rare in Australia, and all efforts are made by zoos and private fanciers to increase the native population. However, more common forms in Australia, which are still rare and expensive overseas are those in general bred in large numbers by the zoos for export. This leaves the native wild population alone, and of course actually increases one’s knowledge of bird breeding. It would be wonderful if other zoos, in other lands, used this method to send native species to zoos, instead of resorting to the capture of wild specimens to fulfill the needs of collectors. It has placed upon the Australian zoo the burden of doing its best, and I found that in some zoos the bird curator has been given greater liberty than in past years. For instance, as many pens as possible have now been converted to more natural exhibits in Sydney than previously was the case, resulting in improved hatching successes. This of course also has brought not only the zoos closer together (there is now an Association of Australian and New Zealand Zoo Directors, formed just six years ago) but has even more importantly joined the private fancier and the zoo curator into partnerships that has been of great value, especially in preserving blood lines of exotic gallinaceous birds, doves and pigeons and psittacines. There remains more to be done with respect to trading between New Zealand and Australian bird fanciers and zoos, but a start has been made, brought together by a common need to maintain stocks as long as possible. As regrettable as such a law is certainly it has had many beneficial results in bird breeding and husbandry, so that emphasis has been placed on raising as many forms as possible, and keeping them alive and healthy as long as possible; actions that zoos in other lands could well imitate, instead of striving to import as many species as possible, and breed only those that meet the eye of the interested curator or fancier. How the wild populations would benefit from such a more enlightened view ! In describing the collections I will take them alphabetically. ADELAIDE ZOO, SOUTH AUSTRALIA I am going to put myself out on a limb so to speak here, by stating that the Psittacine collection of this zoo impressed me far more than any other zoo that I have visited in my life. Every feather on almost every bird was in just the right place, feet were in good condition, and breeding is taking place among a great many species. In fact all of the birds at Adelaide look good. There are about 225 species and forms exhibited, which is about the same number as at Sydney Zoo, so the collection is large by Australian standards. The emphasis is on psittacines and gallinaceous birds, about 70 species of the former and 25 of the latter, many breeding with success. In the attempt to keep macaws as long as possible a pair has been induced to breed, which has resulted in a series of hybrids of just about every colour variety possible. Over a half dozen M. L. JONES — SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS 29 hybrids have been reared thus far, admittedly many with vivid oranges, golds and greens predominating (the parents are the Blue and Yellow Macaw A. ararauna and Scarlet A. macao). There are both the Red and Yellow-fronted New Zealand Parrakeets, Barrabands (which in Australia are called Superbs), Regents and several fine Princess Alexandra’s (again the name locally is simply Princess Parrakeet). It was noted that a great many parrots and parrakeets are named differently in Australia than in America and Europe, which no doubt is confusing to many working in this field. The Rosella collection at Adelaide is complete, with all species and subspecies exhibited, and most raising young. The Red- capped or Purple-capped Parrots (P. spurius) were exceptionally well coloured here. There were also Barnards, Cloncurry, Twenty-eight and Port Lincoln’s Parrakeet; almost all of the species of Neophema and Psephotus\ and of course many cockatoos such as Slender-billed, Rose¬ breasted or Galah, Pink or Major Mitchell (never called Leadbeater’s in Australia), Great Palm and all of the other species of Black Cockatoo. The family of Yellow-tailed was very good looking. In the gallinaceous birds, which are housed in a series of large runs, I noted perhaps the finest Swinhoe Pheasant cock that I have ever seen (and a good breeder) several Razor-billed Curassows, my first Mallee Fowl ( Leipoa ocellata), very large Brush Turkeys or Megapodes, California Quail, Viellot’s Fire-backed Pheasant, Germain’s Peacock Pheasant, and some very handsome Burmese Green Peafowl. Dozens of quail and ornamental pheasants are raised here each year and traded to other zoos. Of note in the collection are the last European Flamingoes in Australia; several Little Pied Cormorants; Yellow-billed and Royal Spoonbills; Blue-winged Shoveller ( A . rhynchotis)\ Australian Little Eagle ( Hieraeetus morphnoides) ; many Boobook Owls; South African Crowned Crane; North Island Weka Rail; Pacific Gull, Nutmeg Fruit Pigeon; several Wonga-Wonga and Nicobar Pigeons; all of the large flightless birds — Ostrich, Emu, Rhea and Cassowary; Little Blue Penguin; and a fine series of waxbills finches and weavers. Unfor¬ tunately many of the aviaries are very old, however, replacements are being constructed as fast as funding will allow. All zoos in Australia are finding it difficult to secure money for capital improvements, and for many there is a need for new and more modern exhibits. Zoos are popular in all of Australia, and many now have various education pro¬ grammes under way involving the school age children and adults. Again almost all are now directed by men who have been in the job less than six years, men with far more vision than their predecessors and more willing to co-operate with sister institutions. Here at Adelaide the Director is Dr. W. E. Lancaster, a veterinarian who formerly lived for many years in Malaysia, working in fact with a colleague who now runs the Toronto, Canada Zoo (Dr. Norman Scollard). Adelaide of course is well known for its large mammal collection, however this will not be discussed here. The zoo unfortunately has rarely been visited by Americans or Europeans 30 M. L. JONES — SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS in the zoo field, an oversight that I hope will be rectified in the future, for it is well worth taking the extra effort to visit. THE SIR COLIN MACKENZIE SANCTUARY, HEALESVILLE, VICTORIA Another zoo that has been rarely seen by fellow Americans, but known due to the work some years ago of a former Director, Dr. Fleay, is this paradise called the Sir Colin Mackenzie Sanctuary. Actually the fauna park that is open to the public, in a setting of large gum trees and native shrubbery, is only part of the 448 acres devoted to the sanctuary, located about 40 miles from the centre of Melbourne. I was very impressed with the care taken not only of the animal collection but the botanical preserve. Much like my colleague, Dr. Grzimek of Frankfurt, I could have spent days here enjoying the wonderful scenery and observing the fauna. Many species are of course wild within the vast limits of the sanctuary (which cannot be visited by the public) and free within the park itself are over 200 White Ibis ( Threskiornis molucca) and about 100 King Parrots ( Aprosmictus scapularis). The latter especially are beautiful, alighting in several areas of the park, much like pigeons in the zoos of the United States, and feeding from the hands of visitors. But the prize of Healesville, and I might add, its proudest possession, are the Superb Lyrebirds. The Lyrebird ( Menura superba) is the only species of bird that cannot be exported alive under any circumstances. Under complete protection it has managed to increase in numbers and in fact wild birds may be found not too many miles from the fauna park. It is however very nervous and secretive, and wild birds are rarely seen by human observers. Within the fauna park there is a huge cage, several hundred feet long, replete with dense vegetation and only a narrow twisting path for visitors (and then open to the public only for a few hours in the afternoon), for just one pair of birds. It was my great thrill and pleasure to be allowed by the Director, Mr. Vernon Mullet, to see the male Lyrebird in his mating dance. Just a few minutes after I came to the park, about ten in the morning, he started to call, and what a piercing call it is. The Lyrebird is a mimic, and a superb one at that, but the range is high and one could hear it all over the park. We entered the cage, and moving about quietly and softly came upon him at the start of his dance. Fortunately I was able to get a few pictures of this, despite the darkness of the cage, and the denseness of the planting. The dance lasted about 15 minutes and all the while he would call. Certainly a sight that I will long remember, and one seen by few Americans. Nothing can quite describe the beauty and the gracefulness of this performance, the long tail feathers moving like so much rustling silk, so unlike the feathers of any other bird. The sanctuary has been able to hatch one bird thus far, and a new aviary is planned for it. In fact two large new aviaries were under construction for the expanding Brush Turkey collection, the aim being to breed as many as possible and to keep them for further study. Most of the aviaries, except for a few small parrakeets, are set in the landscape and M. L. JONES — SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS 31 one comes upon them rather unexpectedly. There is a fine walk-through aviary for native waterfowl and shorebirds. Nearby is a large man-made lake, holding many millions of gallons of water, on which many rare Australian waterfowl will be kept. On my visit I managed to see my first ever living Musk Duck ( Biziura lobata), and also of note were a dozen Eyton Tree Duck. Other birds in the collection were several Brolga or Australian Cranes (which also have been bred here); Fairy Penguins; seven Wedge-tailed Eagles living in a very large and quite unusual cage that was rectangular in shape, and merely was netting hung on large telephone poles, placed at outward angles. The cage was large enough for the birds to fly about, and in it were many living trees. I also saw several Satin Bowerbird; 12 Chestnut-breasted Teal; nine Cape Barren Geese; over a dozen Royal Spoonbill; four Gang Gang Cockatoo; about 15 Turquoisine Parrakeets; several Swift and Musk Parrots; Pale-headed, Crimson, Green, Adelaide and Western Rosella; Blue-bonnet and Red- rumped Parrakeets; and four Boobook Owls. Again there are many mammals here such as Platypus (which also lives wild even within the great fauna park) and native reptiles. The overall theme of course is species native to Australia and Tasmania. Like the larger zoos it charges admission. While in some lands it might not be called a zoo, it is recog¬ nized by the federal Australian Government as one of the six class A zoos in the nation. MELBOURNE ZOO, VICTORIA Well known to many American and European zoo men due to the fact that it carries on a large animal exchange programme, Melbourne is again an old zoo, struggling to build new quarters and expand its collection, despite strict import regulations. Unlike some of its sister institutions, however, it has secured funds necessary for a ten-year programme of construction, already evident in the largest in-zoo Lion Park anywhere in the world, a new Reptile House and new exhibits for large mammals. The zoo has a long series of aviaries which are used exclusively for the raising of native Australian species for export and for fanciers. I would say there are about 80 pens, all are relatively new, adequate and successful. Breeding probably is carried on more than at Adelaide, although there does not appear to be quite as full a range of species. I would say about 40 species of psittacines. There are large flight cages, perhaps larger than any in Europe or North America for terns, gulls, cormorants, waterfowl, and birds of prey. In addition there are dozens of conventional cages, and of course some in need of replacement. All are kept clean and the birds look well. Of course many forms that we would consider exotic here in America, are common in the areas right outside Melbourne, such as cockatoos, so one finds all too often cages that are literally crammed with birds. I counted at least 100 Sulphur-crested Cockatoos and then gave up. There were several dozen Pennant Parrakeets, which again are native to this part of Australia. Melbourne is especially successful in the 32 M. L. JONES — SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS raising of Cape Barren or Cereopsis Geese, over 20 hatched in 1968 alone, and I counted no less than 16 birds in various parts of the zoo. I also noted a new race of Skua for me, S. skua lonnbergi , the Southern Skua; one Australian Pelican (this species is rarer in Australian zoos than in Europe or America); a pair of Indian Adjutant Storks that have been in the zoo for 40 years, but which only last year started to make a nest, after being moved to a new cage — their first next-building attempt in the zoo (extraordinary!); many Philippine Land Rails; Nankeen Night Herons (which are also wild in the zoo and raise many young each year); about 17 Eyton Tree Duck; five Semipalmated Geese; a pair of Sarus Crane; Whistling Eagles (H. sphenurus) ; Gang Gang Cockatoos, and again both of the New Zealand Parrakeets. The collection is good, well cared for, and well worth seeing. TARONGA PARK ZOO, SYDNEY, NEW SOUTH WALES This is of course the zoo best known outside of Australia, although its specific collection may not be. It is the largest overall zoological garden, both in land area and in terms of size of the animal collection. There are about the same number of bird species as Adelaide, however, the variety is somewhat different. It is the last zoo with Birds of Paradise, all having come from the collection of Sir Edward Hallstrom, who no longer has a collection at Mona Vale. Unfortunately, as is well known, Sir Edward has a passion it seems for concrete, and almost all of the aviaries were floored with tons of concrete and in fact many cages are of this material alone, save for the wire. In recent years much of this has been torn up, and an effort made to make the aviaries as natural looking as possible. Emphasis has been shifted also to hatching and breeding as many species as possible. The bird keeper here is a gifted man and is doing a wonderful job. The zoo also is the recipient of many birds that have been taken from airplanes and ships in the smuggling process, too many do not survive being placed in tight airless quarters, but of those that do make it, the zoo does its best to house them properly. It was here that I saw some of the unique devices used to try and smuggle | Golden-shouldered Parrots out of Australia, really just cages inside attache cases, with little air, and no room to move. But with fanciers and zoos in Europe and American willing to pay several thousand dollars a pair, the traffic goes on. I would like to add here, that collectors should insist on knowing the origin of all birds of this rare species bought from exotic animal dealers, and not traffic in illegal birds. For it is the birds that are suffering. What of the collection at Taronga Park? Well it is growing in many areas, in fact in some species hatching has been so successful that birds are being offered to foreign zoos as well as to collections within the nation. Many however, are very rare, and care is being taken to keep them alive and healthy as long as possible. Here are the highlights of the Taronga collection of birds: six Australian Cassowary (and three other cassowary M. L. JONES — SOME BIRDS IN SOUTH-EAST AUSTRALIAN ZOOS 33 species also); four Kiwi; over 40 Little Blue Penguins; one Australian Pelican; two Blue Herons ( Demigretta sacra) ; two White-faced Herons; 17 Chilean Flamingoes (all over 20 years of age); about two dozen Semi- palmate d Geese; about 15 Eyton Tree Duck; four each of Australian and New Zealand Shelduck; two Grey Teal {gibber if rons) ; about 20 Black Swan; one female New Guinea Harpy Eagle {Harpiopsi novaehollandiae the only one in captivity, and again over 20 years old; eight Wedge-tailed Eagles (this species is still killed by farmers in Australia) ; a trio of Andean Condor; six Brush Turkeys; about two dozen King Quail {Excalf actor ia chinensis ); about two dozen Blue Peafowl; Lineated Pheasant; one Sarus Crane; one East African Crowned Crane (last in Australia); one Stanley Crane; two Australian Bustard; about 150 Jobi Dove {Gallicolumba jobiensis ); about 50 Nicobar Pigeon; 20 Victoria Crowned Pigeon (all over 20 years old); several Spinefex Pigeon; about 55 Rainbow Lorikeet {Trichoglossus h. moluccanus); five Palm Cockatoo; six male Eclectus; a pair of Glossy Black Cockatoo (C. lathami)\ about 80 Sulphur-crested Cockatoo; about 40 Little Corella Cockatoo; about 70 Pink Cockatoo {Leadbeater' s) ; 25 King Parrots; 30 Pennant Parrakeet; 20 Pale-headed Rosella; about 60 Elegant Grass Parrakeets; 15 Swift Parrots {Lathamus discolor ); more than 100 Rose-faced Lovebird (one huge group); nearly 50 lutino Indian Ring-necked Parrakeet; the last White-crested Turaco in Australia; a male New Guinea Coucal; about 15 Tawny Frogmouths; one pair of Blue-winged Kingfisher {Dacelo leachi) with one bird hatched in Taronga this past year; no less than three dozen Kookaburra (this is a common local form, brought to the zoo like starlings are brought to zoos in America); a female Dollar Bird {Eurystomus orientalis)\ many rare Australian Honey-eaters such as Lewin {Meliphaga notata), Noisy Miner {Myzantha) ; Noisy Friar-bird (. Philemon ); two male Superb Lyrebirds; Black-backed Piping Crow (which also is wild in the park); Brown and Pied Currawongs {Strepera intermedia and graculina ); a pair of Regent Bowerbirds; Great Bower Bird {Chlamydera nuchalis)\ eight Satin Bower birds; about 100 Java Sparrow; 60 Zebra Finch; and in birds of paradise —four Black Manucode {Phonygammus keraudreni) ; one Green Manucode {Manucodia chalybeata orientalis)\ male Ribbon-tail {Astrapia mayeri); female Lesser Sickle-billed Bird of Paradise {Epimaches meyeri ); male Prince Rudolph’s Blue; female Finsch’s Lesser Bird of Paradise; female Emperor of Germany’s Bird of Paradise ; male Stephanie’s Bird of Paradise and a single male Count Raggi’s Greater Bird of Paradise, all of these birds having been in Australia almost 20 years and captured adult. Director at Taronga is Dr. Ronald Strahan, a professional zoologist who is creating a new staff with emphasis in education. I might have added that labelling in all of the zoos is excellent ; in most there are coloured paintings of the birds and range pictures, this perhaps best at Sydney and Adelaide. # * # C 34 OBITUARY OBITUARY A.S. 1879-1970 Allen Silver died in Llantarnam, on 4th January, 1970, in his 91st year. Born at Long Melford, Suffolk in 1879, he had the inborn interests of a countryman. Very early his leanings veered largely in the direction of British passerine birds and although he specialized in passerines and picarenes he was, nevertheless, keenly interested in all birds, whether ornamental pheasants, waterfowl, show or utility poultry or pigeons; in addition, he took no little interest in mammals, fish and insects. At one time or another he owned examples of the majority of European cage-birds and a very large proportion of the imported exotic species, varying from sunbirds to macaws. As far back as 1895 he was appointed a judge of cage-birds and from then until very recent times he officiated at shows throughout the country. He judged at many Crystal Palace Shows, both before and after the first World War, and the National was not, of course, complete without his presence. In his time he was a very prominent exhibitor, staging as many as sixty birds at a single show. In the late 1920s he won all the principal Budgerigar trophies, several outright. He was elected a Member of the Foreign Bird Club in 1903, and of the Avicultural Society in 1904, of which he was doyen and Vice-President since 1958. With several others he founded the Budgerigar Club, of which he was Chairman for the first three years, also Editor of the Budgerigar Bulletin for the same period. Long before this he was closely connected with the National British Bird Club, the London Cage Bird and London Provincial Ornithological Societies, and in 1911 he resuscitated the Foreign Bird Exhibitors’ League. Allen Silver contributed only infrequently to the Magazine but his writings were many and varied. He revised Bradburn’s Book of British Birds; compiled The Birdkeepers ’ Guide; wrote British Bird Management , The Parrot Book and the bird section of The Wonder Book of Pets. He was on the staff of Canary and Cage Bird Life during its existence, British and foreign bird expert to The Feathered World , and, of course, foreign bird expert to Cage and Aviary Birds. Despite the incredible hardship of losing a leg in the 1914-1918 War, Allen Silver was ever cheerful and always so willing and helpful. A natural gentleman and a great bird-lover his passing leaves another unfillable gap. A. A. P. NEWS AND VIEWS 35 NEWS AND VIEWS E. Norgaard-Olesen, Janderup, Denmark, reports the rearing of a Fire-fronted Bishop. One Blue-naped Mousebird Colius macrourus was bred and the Red-faced C. indicus had eggs. * * # The Simon Harvey Memorial Medal, awarded annually by the Avicul- tural Society of South Australia for the most outstanding breeding achievement of the year, has been awarded to Russ Rowlands, for breeding the Green Catbird Ailuroedus crassirostris, 1968-69. # # # Paul Farrant: “ I bred five young Redrumps, and was interested to find that when the hen died, the young were only three weeks old, the cock carried on and brought up all five young quite successfully.” * # # Major Iain Grahame reports that Vulturine Guineafowl have again been bred at Daw’s Hall Wildfowl Farm.

Some of the young ones went to Derek England and a brother and sister successfully carried the breeding to the second generation. England is naturally anxious to obtain some new blood! G. R. Phipps, Greenacre, New South Wales: “ I was very interested to read Guthrie Hall’s report (1969, 113) on the Golden Pheasant which “ changed its sex ”. I, too, have a hen in my collection which except for the lack of a white ring around the eye, and for the fact that the wing primaries are heavily suffused with browTn, is in every way identical to a cock” * * * Allen Silver wrote: “A correspondent, Mrs. P. Shepherd, Dukeswell, nr. Honiton, Devon, informs me that her pair of Quakers raised seven in one round in 1968, and this year ten youngsters in two rounds — 17 in two years. The breeder lost two from the first round ; one from a burst blood vessel(?) and another from coming out too early and dying from exposure to deluge from storms.” * # # The Cream-coloured Courser Cursorius cursor cursor , an Ethiopian and S. Palaearctic species is a rare vagrant in Great Britain. The advent of one in a sugar-beet field, near Great Yarmouth, towards the end of October, caused very great interest and many ornithologists 36 NEWS AND VIEWS visited the area in the hope of seeing it. But unfortunately it survived only a few weeks: it was found badly mauled, presumably by a cat. * * * Dr. E. P. McCabe, Jr., San Antonio, Texas: “ I reared five Cloncurry Parrakeets during last spring and summer. The first clutch of two proved to be a pair. The adults again went to nest in May. The cock died soon after the hen commenced incubating but she hatched three chicks which I hand-fed and successfully reared. As they were two cocks and a hen I now have three each of both sexes.” * # # The Royal Zoological Society of South Australia reports that during the 1968-69 season 134 birds of 37 species and varieties were bred in the Adelaide Zoological Gardens. The outstanding event was the breeding of three Banded Landrails Hypotaenidia pliilippensis , a probable “ first ” in the Gardens. For the fifth year running a Blue and Yellow x Scarlet Macaw hybrid was reared. A Leadbeater’s Cockatoo was reared, the first in 15 years, also six Queen Alexandra’s Parrakeets. The Rosellas did particularly well, six of the ten species in the Collection — Yellow, Northern, Western, Eastern, Golden-mantled and Pale-headed — reared 16 young between them. The Brush-Turkeys Alectura lathami again did well, 24 young hatched from the mound and only three failed to survive. * * * Hartley King: “ We have had a very dry winter here in Western Australia, and there is little prospect of much rain during the forthcoming summer. The effect of this is very noticeable in the breeding habits of our wild birds and wildlife generally. The marsupials are withholding their young; the waterfowl have had such a poor season that duck shooting is to be prohibited; our parrots that would normally have young on the wing have not gone to nest yet, and so on. Most of the farmers’ dams are dry, and water restriction will be inevitable before Christmas. This trend is reflected in our aviary birds, but not by any means to the same extent. My pair of Banded Plovers have already raised three young and are nesting again. (Last year — from June to June — they raised six lots of chicks.) My Neophemas have made a good start; Scarlets, Turquoisines and Bourkes have chicks; Crimson and Pale-headed Rosellas, Barrabands, Kings and Cloncurries have gone to nest. Likewise the Blue Mountain, Scaly and Varied Lorikeets. The finches have been in full swing for some time: Masked, White¬ eared Masks, Gouldians, Long-tailed, Parsons, Diggles, Stars, Pictorellas, Chestnuts, Orange-breasteds, Fires, Double-bars, etc.” NEWS AND VIEWS 37 A world record auction price for a printed book of £90,000 was paid at Sotheby’s on 24th November 1969 for a copy of Audubon’s “ The Birds of America Sold anonymously it was bought by Mr. Kenneth Nebenzahl, a Chicago bookseller. The almost unbelievable price is accounted for by the fact that this very rare work is a superb copy ‘ in the finest possible condition ”. John James Laforest Audubon (1785-1851) was the illegitimate son of a Creole and a French naval officer, who adopted him and took him to France, where he studied painting and developed a love for natural history. North America became his home but due to his passion for bird painting various business ventures did not thrive and he was forced to support his family by painting portraits. Returning to Europe in 1821, successful exhibitions in Liverpool and Edinburgh encouraged him to issue a prospectus of a work that was to ensure him a place amongst America’s immortals. “ The Birds of America ” was issued without text (which followed in 1 83 1~39 under the title “ Ornithological Biography ”) during 1827-38, in 87 parts of five plates each. It was published at two guineas the part, or £182 14s. od. the set ($1,000 in the U.S.A.). The 435 copper-plate engravings, coloured by hand, contain 1,065 fife-size figures of 489 supposedly distinct species. It is believed that fewer than 200 complete sets, usually four volumes, were bound up. * # # In a review of “ Henry Walter Bates ”, by George Woodcock, in The Geographical Journal , September 1969, 456-7, Dr. Edward Hindle refers to a plate in The Naturalist on the River Amazons , by H. W. Bates, showing the author being mobbed by toucans. It may not perhaps be without interest to recount Bates’ account published in 1863, of the affair with the Curl-crested Toucan Pteroglossus heauharnaisii. He writes: “ I had an amusing adventure one day with these birds. I had shot one from a rather high tree in a dark glen in the forest, and entered the thicket where the bird had fallen, to secure my booty. It was only wounded, and on my attempting to seize it, set up a loud scream. In an instant, as if by magic, the shady nook seemed alive with these birds, although there was certainly none visible when I entered the jungle. They descended towards me, hopping from bough to bough, some of them swinging on the loops and cables of woody lianas, and all croaking and fluttering their wings like so many furies. If I had had a long stick in my hand I could have knocked several of them over. After killing the wounded one I began to prepare for obtaining more specimens and punishing the viragos for their boldness; but the screaming of their companion having ceased they remounted the trees, and before I could reload, every one of them had disappeared.” A. A. P. 38 NOTES NOTES THE ADVENTURES OF AN ESCAPED RED-BILLED BLUE MAGPIE , Last June the cock of a pair of Red-billed Blue Magpies escaped. This I 1 discovered when it appeared suddenly on a fence, bowled a grey squirrel head-over- . heels, stole a nut it was eating, and disappeared into the blue. Normally I get innumerable reports when one of my birds escape but strangely enough I heard nothing of this bird until mid-November when I received a telephone call asking if I could identify a strange bird which had been resident in a strip of woodland in Riddlesdown since last June, and which regularly visited four or five gardens backing onto the wood. Apparently a report had appeared in the local press two weeks previously, but I had missed it. From the description I was pretty sure it was my magpie, so on the following Sunday I took the hen, in a large parrot cage, and a trap cage, up to one of the gardens it was said to visit daily; arriving at 8 a.m. when it was still only just getting light. As I was hoisting the cage onto a shed roof I heard the bird “ chuckle ” some distance off, and the hen promptly replied. The trap cage, baited with mice, I put on top of the parrot cage, and retired to a garage with a convenient window overlooking the garden. Within five minutes the cock was on the shed roof, rushing round and round the cage, displaying just like a golden pheasant, with j tail spread, wing trailing and body twisted towards the hen. Twice he fell off the roof in his excitement, once he caught the tip of the hen’s tail through the wire and nearly pulled it out. Then he sat still for about five minutes, apparently to recover his breath before again circling the cage, and at last jumped up on top, onto the trap, where he spotted the mice and without hesitation dived in. The lid came down with a smack but he never even glanced up, just grabbed a mouse and commenced eating. By g a.m. he was back in his aviary, both he and the hen having eaten five mice between them on my journey home. The next day he sulked, but the day after was completely rehabilitated and seemed tamer than he was prior to his escape. He was in perfect condition, having evidently moulted during his freedom, his bill and legs being now deep orange (they had faded to dull yellow in the aviary), and strangely, one central tail feather which had always been slightly faulty was now pure white. K. A. Norris. CORRESPONDENCE VITAMINS AND FRENCH MOULT So much has been written on feather malformation generally, and French Moult in budgerigars in particular, that I hesitate to take up more space on this subject. It is, however, an important matter, especially to the afflicted birds, in whose interest I feel prompted to write. One of the main factors making birds aware of the advent of the breeding season is the production in their bodies of vitamin D by the action of the ultra¬ violet rays in sunlight on a substance called ergosterol in the body. This oil- soluble vitamin is popularly called the sunshine vitamin. Most budgerigar breeders start the season early, in the short winter days when little ultra-violet light penetrates our atmosphere, and they therefore add vitamin D to the diet, usually in the form of cod-liver-oil added to the seed. However, Vitamin D is not something of which it may be said that if a little is good a lot will be better. Too much is harmful to human beings, causing excess calcium and phosphorus retention and a rough skin condition. There is, of course, no harm done in feeding the small amount of cod-liver-oil recommended by the makers to bring the birds into condition, but it must be remembered that what is the correct amount in the short winter days can be excessive when the birds are producing their own vitamin D in spring and summer conditions. CORRESPONDENCE 39 I believe that the supply of vitamin D by oil-soaked seed should stop well before the young are due to hatch, as apart from the vitamin being cumulative in the body, in the wild state the young of virtually all parrot-type birds do not emerge from a dark nest-hole until fully feathered, and clearly will receive only the very small amount of vitamin D provided naturally by the parents during the feather-forming period. No theory can be proved without a number of controlled tests (which I unfortunately do not have the opportunity to carry out), but in support I can quote from my own experience some years ago when breeding from four or five pairs of budgerigars. The birds were kept outside and the first early round with cod-liver-oil and artificial light to lengthen the feeding hours was quite successful. Cod-liver-oil was continued throughout the season, and all subsequent young with the exception of two albinos had malformed feathers to a greater or lesser extent, many being cases of French Moult at its worst. It would be wrong to suggest that only budgerigars can be fitted into this theory, but they are the species most prone to French Moult and they do feed their young on a regurgitated paste derived from the seed provided. I would also, in con elusion, like to quote from an excellent little book which I read recently “ Halfmoon and Dwarf Parrots ” in which the author, William Allan, advises strongly against keeping a caged bird by a window. Apart from the draught possibilities he writes (in Dallas, Texas, where the sun is the large de luxe model) that the sunlight causes the bird to undergo a continuous moult. I find the connection between excessive vitamin D and feather abnormalities inescapable, but it would require a lot of feeding trials to prove it. The Garden House, R. W. Phipps. Battlemead Close, Maidenhead, Berkshire. RELEASING BIRDS AT LIBERTY OR SEMI-LIBERTY Like many members, I am sure, the correspondence about foreign birds being released in the countryside — whether by accident, intention, or “ controlled liberty ” — has been of great interest to me. I am certain that the participants in the debate have all seen the current issue of Ibis , but for members who have not it may be of interest to make note of a letter from R. O. Vicente in Portugal. The letter is headed “A new introduced species in Europe: the Red-eared waxbill ”. The substance of the letter is that Estrilda troglodytes has been observed living and breeding in the wild in Portugal on several occasions during the past five years. Flocks of up to 300 have been observed, and both nests and juvenile birds have been seen on various occasions. The purpose of Mr. Vicente’s letter was to ask for any ornithologists holidaying in Portugal to keep an eye open for the species and report it. Having newly arrived in Madrid where I expect to live for the next couple of years, the letter is of extra interest to me. This is not the point though. The existence of ringed individuals in the flocks shows that they are almost certainly from an avicultural source, so the culprits are known though their motives are not. It remains to be seen how well the Red-earned waxbill establishes itself in Portugal; if holidaying bird watchers do oblige Mr. Vicente, and the species can be shown to have claimed an ecological niche in competition with local avifauna then the contributors to the debate will surely be nearer a conclusion. c/o J. Walter Thompson Company S.A., Robin L. Restall. Arapiles 13, Madrid 15, Spain. 4o CORRESPONDENCE LONGEVITY IN PARROTS I am writing in response to your request in the September-October issue of The Avicultural Magazine for information on cases of longevity in parrots. On 1 2th May i960, I obtained from Mrs. Dale Ellenberger of this city the body of a male Amazona aestiva aestiva (the Brazilian race of the Blue- or Turquoise- fronted Amazon). This bird had been in the continuous possession of Mrs. Ellenberger’s family, and I was told that it had been purchased in Rio de Janeiro approximately 70 years before its death; the family did not have the exact year, but according to family tradition, the bird was about 75 years old at its death. The bird was in excellent condition, with moderately enlarged gonads, and was just completing a moult. I made no attempt at autopsy; in view of the known great age of this bird, I thought its body might conceivably be of interest to some researcher, so I prepared a study skin (Carnegie Mus. no. 139,369) and preserved the remainder of the carcass in spirits (C.M. alcoholic collection no. 844). I hope this information is of interest to you. Carnegie Museum, Kenneth C. Parkes, Curator of Birds. Pittsburgh, Pennsylvania 15213, U.S.A. Concerning the note in The Avicultural Magazine about longevity in parrots, I wonder whether the following may be of some interest. A good many years ago, while I was at the London Zoo, I was called upon to go to the house of a Harley Street specialist — actually to remove a closed ring from the leg of a canary, which had become embedded in the flesh and which, incidentally, was successfully accomplished without any harm resulting. In conversation afterwards, the gentleman showed me an African Grey Parrot which was in a large cage in a front room overlooking Harley Street and told me that to his undoubted knowledge, it had stood there for the last 60 years. As it was in excellent condition, there could have been no reason to suppose that it might not continue to stand there for many years afterwards. Judging between this species and the common species of Amazons usually kept, it does seem in my experience that the former often excels in longevity, as I, when Overseer of birds, received many queries by phone and otherwise, concerning Amazons which through weakness apparently due to age, were unable to perch after reaching an age of from 30 to a maximum of 40 years to their owners knowledge ; although, of course, there may be many exceptions. Cockatoos, as everyone knows, are very long-lived but one does not hear so much about Macaws, perhaps because they are not so easy to house for the ordinary person. 53 Dollis Road, E. B. Tanner.

Restall (Madrid, Spain) Some years ago I noticed an advertisement by Mr. C. Hill of Pinner in Middlesex for “ Unidentified male Siberian buntings, five only, looks like Shore Lark Nobody could blame Mr. Hill for not being able to identify the species, for a friend of mine who is a professional ornithologist and whom I regard as an expert, was unable to identify it on sight. Sub¬ sequent investigation on his part identified it as the Elegant Bunting Emberiza elegans. I contacted Mr. Hill and discovered that he only had one bird left, but I was fortunate to be able to obtain it. Mr. Hill was very helpful and told me all he knew about the bird, including what he was feeding it on, and we arranged for a mutually convenient transport date. Eventually the bird arrived. I was looking forward to seeing it very much for of all the reference books I have the only one to mention the species was Aviculture , which said of it: “ Said to be a favourite cage-bird of the Japanese on account of its song and doubtless, also, of its charming colouring (then followed a description). . . . This pretty bird breeds at Ichang and Sechuen, is probably resident in Japan, visits Manchuria and the valley or Amur in summer, and is a common winter visitor of China, where it frequents the hillsides, bamboo clumps, and rough scrub around farm clearings; its nesting-habits are probably similar to those of other species of the genus ”. More recently I have referred to the books by La Touche (1925), Seebohm (1890) and the Caldwells (1931) to pull together notes on distribution, local habitat and description of the races. I have not had the opportunity of examining skins of the species, but have learned of the areas from which those in the collection at the British Museum (Natural History) have come, and these have been borne in mind. Yamashina’s book on the birds of Japan only gives the barest reference, so I have not used it. Mr. Allen Silver very kindly wrote to me on the subject as follows “ . . . the Zoo had it previous to 1929 but have no account of it since. Taka Tsukasa in Aviculture in Japan (see page 36) mentions it as being kept among other buntings there. . . . These several buntings are kept for their song, which like the quails kept in the past for their call, are repetitious rather than musical to our ears E 42 ROBIN L. RESTALL — THE ELEGANT BUNTING The English names for the species are confusing, but Yellow-browed and Yellow- throated Bunting are the commonest. I have chosen to call it the Elegant Bunting, the name used by Mr. Silver, but one which he thought particularly inappropriate. Personally, I find this bird extremely attractive and elegant, and, in fact, one of the most appealing of all buntings I have kept (Ember iza or Passerina). As it is virtually unknown in this country I will describe it in some detail. The adult male is about 6 in. long. Its forehead and crown, sides of head, chin and a large crescent-shaped patch across the breast are all black. The superciliary (eyebrow) and sides of the neck, back of the crown and throat are bright yellow. The nape is black, while the lower hind neck is grey, marked with black and chestnut. The feathers of the crown are elongated into a half crest which can be erected at will. When fully depressed, the yellow crescent immediately behind the crest is covered by it. In winter the black head feathers are edged with brown and the feathers of the hind neck are more noticeably streaked. The back is chestnut, the rump is grey, and the upper tail coverts and tail are greyish brown. The outer edges of the outer tail feathers are white. The wings are mainly black, with pale chestnut edges. The tips of the median and greater wing coverts are very pale buff, nearly white, forming two broad wing bars. The innermost secondaries are black, broadly edged with brown, while the secondaries and primaries are dark brown edged with brown. Below, the bird is white, tinged with rufous on the flanks which are also streaked with long chestnut stripes. As the winter proceeds the brownish edges to the feathers of the head and neck wear away and the bird looks sharply and more strongly pencilled above. The adult female is similar to the male, but differs in the following respects : the black of the head in the male is brown in the female, the yellow of the head is duller and less extensive, and only a tinge on the throat. The breast crescent is reduced to vestigial traces, and in some individuals is missing altogether. In the winter plumage the throat and upper parts are more infused with brown or buff. The edges to the feathers being broader the back looks browner. In both sexes the iris is brown, the legs are flesh, and the bill is black in summer and brown in winter, with paler lower mandible. Immature birds resemble adult females but are possibly browner on the throat and head. It is a bird of great character, imparted largely by the head charac¬ teristics — the strong bandit’s mask and the stylish crest which is raised and depressed at will. The only illustration I have found is a photo¬ graph of a male on the nest (Hanzak, 1967), but Mr. Silver’s encyclopaedic knowledge wrote: “ . . . there is a figure of it in Jap. Aves, 1850, pi. 55, by Temminck and Schlegel. The one I possess is that in Birds of Japan, by Ksisuke Kobayashi, illustrated by Takashi Miyamato on plate 6 YeMmd ROBIN L. RESTALL — THE ELEGANT BUNTING 43 44 ROBIN L. RESTALL — THE ELEGANT BUNTING Races and Distribution Professor Sushkin defined three races which are briefly as follows: Emberiza elegans elegans (Temm.), which has been referred to elsewhere as Temminck’s Yellow-browed Bunting. It is distinguished by having strongly streaked flanks, black on chestnut. This is the northern race, an uncommon resident in Japan and Manchuria, breeding in Amurskaya (Amur or Amoor in the literature) and probably resident in Korea. It winters in China wandering as far south as the Yangtse Kiang. E. e. sibirica (Sushkin), sometimes called Sushkin’s Yellow- throated Bunting is the Chinese race, ranging from Kiangsu southwards to Kwang- tung (Hong Kong, to assist the reader in his geography). It is the least strongly marked, being greyer on the nape and having the flanks scantily marked with narrow streaks. It is the race in my plate. E. e. elegantula (Swinhoe) is browner and darker above than either of the others, and the flank stripes are very broad. It is the mountain race ranging from Manchuria down to N.W. Fukien. It, too, breeds in the northern parts and winters in the south. Habitat and Habits According to Hanzak its favourite haunts are young oak woods, but the Caldwells are more helpful, saying it is found working on grassy plots under certain hardwood trees, scratching under the leaves for buried seeds. They say it is friendly and confiding being found usually in loose colonies which permit a close approach for observation and study. All that La Touche has to say on the subject is that it winters in south-eastern Manchuria in sheltered woods and valleys, and Butler’s comments are mentioned earlier above. Unfortunately my bird had a broken wing, and so its behaviour could hardly be termed normal. However, it was in excellent physical con¬ dition and certainly seemed full of bounce and energy. It was placed in a roomy outdoor aviary (house n ft. x 9 ft., flight 11 ft. x 17 ft.) which is planted with Cupressus, Finns and various other shrubs, including some ground St. John’s Wort ( Hypericum calycinum) and a standard privet. The bunting shared this enclosure with a pair of Rustic Buntings, Cali¬ fornia Quail, Mesias and a few other medium-sized birds. It settled in immediately, and soon established two favourite spots, the first under a small Lonicera nitida where it was perfectly hidden and from where it could sally forth on food hunting forays. The second was in the heart of a Cupressus where it roosted along with a few other birds. Naturally, I suppose, it spent more time in company with the Rustic Buntings (E. rustica) than any of the other species present. On many occasions, it could be seen working over the grass looking for insects and other items, the three birds forming a loose group. I never saw it doing this alone, although it foraged through the undergrowth by itself (perhaps I should ROBIN L. RESTALL - THE ELEGANT BUNTING 45 explain that the aviary is divided longitudinally, the front half being “ lawn ” and the rear being shrubbery). I put it outside at the end of the autumn, 1967, and there it stayed until mid-March when it was given to Mr. Yealland at the Zoo. I always throw a handful of mealworms around the aviary at feeding time, as this prompts rather more natural behaviour than simply using pots on a shelf. On several occasions, the bunting would dash out from beneath the Lonicera and seize one, mumble it in its beak for a minute, and then run back under cover. It never seemed to show the slightest sign of aggres¬ sion, although this could be explained by the fact that its injury must have kept it below peak condition. It never sang either. The Pekins are said to prize it as a songster (La Touche), and it is kept as a cage bird for this reason. What its song is really like I cannot say, but there is no doubt that Oriental ears like different sounds or qualities to western ones, and several species that are kept as cage birds for their song could hardly qualify in the west. The crest is completely inconspicuous when depressed and runs down into a black crescent on the nape; mostly, however, it is very slightly raised giving an impression of slightly elongated feathers. Frequently it is raised to the extent shown in my picture, and higher. Mr. Hill made the following comment in a letter to me about them: “ . . . have noticed they raise their crest when aggressive and trill like a waxwing, but their alarm note is just like a Yellowhammer’s ”. It seemed to me that the crest was raised whenever the bird was excited, be it alarm, curiosity or what. Food The natural food must be described as various small seeds and insects, the callow young being fed entirely on insect life, which is predictable and not very helpful. Most avicultural text books suggest “ canary seed, millets, oats and hemp ” for buntings en masse, but the bill of the elegant is fine and light and seems inadequate to deal with dry hemp and oats. Mr. Silver kindly gave me a reference for an article in the Avicultural Magazine (3rd series, Volume XIII, 1922) by Taka Tsukasa which apparently describes how the Japanese feed their buntings on soft food. Unfortunately, I do not have this so cannot give details here. My Elegant Bunting had access to canary mixture, mixed millets, Haith’s English Weed seeds mixture, and Sluis Universal grade Softfood. The latter was placed in a bowl on the floor and was only taken in small quantities; of the former it is impossible to say what was taken or what the preferences were. Mealworms and maggots were both taken eagerly. Mr. Hill told me that he had kept them on plain canary, mixed millets, maggots, mealworms and softbill food. 46 ROBIN L. RESTALL — THE ELEGANT BUNTING Nesting Although there are large gaps in my study of the literature, it seems as though the species has not been bred in captivity, at least in Britain. It is a ground nester, and so would not require any special pans or receptacles, but clearly would require suitable cover. The nest is built of soft bents, fine stems, etc., and is always on the ground beneath an overhanging stone, fallen log, over- arching root, etc., amongst bracken, brushwood, or other tangled undergrowth, or Skylark-fashion, beneath a clump of grass. The clutch is normally four or five and they are dirty white with pale violet markings and dark brown spots. According to Hanzak they are double brooded. Summary To the contemporary aviculturist, this is an unknown species and there is virtually no mention of it in the available literature It is a lovely member of the Emberiza genus and would, no doubt, repay study, although it would appear to be fairly typical in most respects. It is hoped that these notes will prompt any other members who have experience of the species to contribute to the common wealth. REFERENCES Caldwell and Caldwell. 1931. South China Birds. Shanghai.

Hodges (Pinner, Middlesex, England) There can be no more satisfying branch of aviculture than that devoted to the establishment of aviary bred strains of various species. Several members of the Avicultural Society have succeeded in breeding many species to several successive generations but unfortunately their experi¬ ences (except those of Nicholson with Red Headed Parrot Finches and Teague with Gouldian Finches) have seldom been documented. The almost complete ban on the export of native fauna imposed by the Australian authorities has provided a great incentive to establish aviary strains of the many attractive Australian species. Fortunately, most Australian Parrakeets and Finches do well in captivity and can be induced to breed. Australian parrakeets make ideal aviary inhabitants and to me the most desirable of them are the Grass Parrakeets. The members of this genus [Neophema) have every conceivable advantage from the avi¬ cultural point of view. They are extremely beautiful, they often become tame and confiding, they are hardy and they are not difficult to maintain and breed. Two further advantages which they possess of particular interest to those of us who are compelled to live in towns and suburbs are that they require only small aviaries and are not noisy. They are not as widely kept as they deserve to be and I have often wondered whether their comparative lack of popularity is due to the pessimistic accounts which the avicultural writers of the 1930’s gave of the ease with which they were supposed to die from all sorts of diseases with almost meaningless names like contagious conjunctivitis and septicaemia. Many of these authors were repeating the gloomy prognostications of the late Duke of Bedford whose lack of success with the Grass Parrakeets was probably due to the fact that he kept them in unsuitably large aviaries in which they were inclined to panic and dash headlong against the wire netting with fatal results. In any case, he was often inclined to make sweeping generaliza¬ tions about a particular species or genus on the basis of a limited experience with only a few specimens. Since 1956, I have kept several pairs of six of the seven species of the genus. Last year I saw for the first time the other (the Orange Bellied) in one British aviary and in several South Australian aviaries. The Splendid ( N . splendida ) is probably the favourite of most Grass Parrakeet enthusiasts but, attractive as it is, I do not think it can compare with the Blue-winged Grass Parrakeet (N. chrysostoma ). My first pair of Blue- wings were obtained more than 10 years ago. At first they lived up to their reputation of being difficult to persuade to breed, but gradually they began to produce a few youngsters and I was able to build up a small stock. In 1964 I obtained a few imported Australian aviary bred 48 J. R. HODGES - THE BLUE- WINGED GRASS PARRAKEET specimens and although for a while the breeding results continued to be disappointing, they gradually improved and during 1967, 1968 and 1969 three or four breeding pairs have produced more than 20 youngsters per year. Breeding pairs have been made up only from the best unrelated youngsters and, as a result, I have been able to develop a breeding strain of prolific, large, well-coloured specimens. The natural habitat of the Blue- wing is Tasmania and coastal areas of Victoria and South Australia. It is reputed to be the most common parrot in Tasmania and, for this reason, I was very disappointed at not seeing any in the wild during a very brief visit to Hobart and its lovely surrounding countryside in October 1969. However, I was compensated for the dearth of Blue-wings in the places I visited by the sight of large numbers of Tasmanian or Green Rosellas ( Platycercus caledonicus) many of which came to feed on the ground within a few yards of where I stood at Port Arthur. Many Blue-wings migrate from their breeding grounds in Tasmania to Victoria and South Australia when the weather con¬ ditions become less favourable and the food supplies scarce. Melbourne aviculturists often find large numbers of Blue-wings around their aviaries at certain times of the year. These are birds on their migratory passage which are attracted by the calls of the aviary inmates. Several of the Australian aviculturists I visited recently keep Blue¬ winged Parrakeets which, even in their native habitat, have the reputation of not being very free breeders in captivity. However, at the Melbourne Zoo, which possesses one particularly attractive exhibit in the form of an extremely well designed range of breeding aviaries for rare parrakeets, the species appears to flourish and one compartment of the range contained at the time of my visit 30 to 40 Blue-wings, all apparently bred at the Zoo. The Blue-winged is one of the largest of the Grass Parrakeets and is about eight and a half inches long. The adult male is olive green on the back, pale green on the throat and chest and yellow on the abdomen and the underside of the tail. The wings are deep royal blue as also is the frontal band and the dorsal side of the tail. The lores and the areas around the eyes are bright yellow. The primaries are black, the bill is almost black and the legs are grey. The female is said to differ from the male in being duller coloured generally. However, individual specimens vary considerably in brightness of colour and the only reliable guide to sex in adults is the jet black of the primaries of the male which contrasts with the brownish black of the female. One of the most attractive features of the Blue-wing is the large round button-like eyes which give it a very bright and intelligent look. It is easy to confuse immature specimens with young Elegant Parrakeets ( N . elegans) but in the adults the differences are very noticeable. Elegants are distinctly more slender, the green plumage has a more golden yellow hue and the frontal band extends behind the eye. The Blue-wing is more olive green and the frontal band is J. R. HODGES — THE BLUE- WINGED GRASS PARRAKEET 49 less extensive. However, the greatest differences are in the blue wing patches which are much more extensive in the Blue-wing and of a deeper blue. Much of this blue is hidden by the wing coverts when the bird is in repose but when it is fully exposed, as for example in display, the Blue¬ winged Parrakeet is quite incredibly beautiful. In the wild Blue-wings feed on the seeds of grasses and herbaceous plants, fruits, berries and small insects. In captivity they do well on the usual diet recommended for Grass Parrakeets. Mine are fed on a mixture containing approximately 50% canary seed, 40% mixed millets, 6% white sunflower, 3% small striped sunflower and 1% hemp. They are given fresh green food in the form of spinach beet, groundsel, chickweed or dandelion, and slices of apple as frequently as possible. They receive millet sprays dusted with P.Y.M. (Phillips yeast mixture) and Haiths Budgerigar Tonic seed at least twice a week. They have constant access to fresh water, mineralized grit and fresh cuttlefish. The water is supplied in a bowl about 8 in. in diameter and 1 in. deep in the open flight and the seed in a similar smaller container in the aviary shelter. The aviary for a pair of Grass Parrakeets should consist of an enclosed shelter, a covered flight and an open flight. The shelter should be well lit and have perches or ledges higher than anywhere else in the aviary to encourage the birds to roost in it at night rather than in the flight. Grass Parrakeets appear to fare better in small aviaries than in excessively large ones. A satisfactory size for a breeding pair is 9 ft. x 2 ft. 6 in. x 6 ft. high. Mine are of these dimensions and are arranged in a series of compart¬ ments. Probably the optimum size is larger and a length of about 12 ft. is desirable. My aviaries are smaller because I live in a London suburb where garden aviary space is severely limited. In very long aviaries Grass Parrakeets are inclined to take fright at night and to hit the far end of the aviary with literally break neck speed. Grass floors are best in the open flight but they quickly become unsightly mud patches in small enclosures. The floors of my aviary flights consist of 2 ft. x 2 ft. frames covered with \ in. mesh wire netting laid on the earth and covered with sand to a depth of about J in. The sand beneath the perches is removed and replenished frequently. In such enclosures with sand floors it is probably beneficial for the birds to have fresh turves placed on the ground from time to time. The perches in my aviaries consist usually of apple tree branches and these are replaced about twice a year. Blue-winged Grass Parrakeets will take to almost any kind of nest box. I use the vertical type 18 in. x 6 in. x 6 in. with an entrance hole z\ in. in diameter near the top and a wire netting ladder tacked inside. They are made from timber f in. thick treated with creosote. About 2 in. of moist peat pressed well down is placed in the bottoms of the boxes and they are hung in the aviary flights at the end of March. The birds almost invariably show an immediate interest in the nest boxes and the hens usually spend long periods scratching about in the peat preparing the 50 J. R. HODGES - THE BLUE- WINGED GRASS PARRAKEET nest. Laying hardly ever commences much before the end of April. In this respect Blue- wings are very dilferent from Splendids and Turquoisines which often start laying a week or so after the nest boxes have been placed in position. I have very frequently had cases of egg binding with Splendids and Turquoisines but never with Blue- wings. They usually lay from four to six eggs on alternate days and commence incubation after the appearance of the second egg. The chicks hatch after 1 8 to 20 days and at first they are covered with grey down. They are brooded very closely by the hen for the first few days and during this period she leaves the nest only very infrequently and is fed by the cock in the nest box entrance hole. When the young are about 10 days old she leaves them for longer periods and the cock often begins to enter the box to feed the chicks. Most of my hens brood their chicks at night for at least three weeks. The chicks can be seen calling for food at the entrance holes when they are about 30 days old and soon afterwards they leave the nest boxes. They are a little timid at first but usually settle down and are flying and perching confidently within a day or so. They are dull imitations of the parents with horn coloured beaks which change to black in two or three months. The hens frequently commence to lay a second clutch of eggs before all the young from the first nest have left the nest box but the cock will continue to feed the chicks which usually become independent within a week of leaving the nest. The youngsters can be left with the parents without coming to any harm but I usually remove those from the first nest before the chicks from the second are flying. Young birds are not difficult to sex at first because the males have brighter blue wing patches than the females but this difference becomes less apparent in a month or two after which it is no longer possible to sex them until they have completed their first moult. This usually takes place when they are about eight months old. Fully mature specimens are almost invariably double brooded. Early hatched youngsters usually have one nest during the following year but those hatched later (second “ round ”) hardly ever attempt to breed until their second season. Blue- wings have no special extra requirements when they are breeding but they should have constant access to supplies of fresh green food, soaked millet sprays and additional hempseed. Occasionally a hen is inclined to lay again long before her first brood has been reared, and deserts it. Hand-rearing of the chicks is very easy particularly if they are not less than about 10 days old. They should be placed in a small box with the bottom covered with plenty of peat to absorb the excreta and kept in a fairly warm place. Many different diets are suitable. I usually stir four teaspoonfuls of “ Farex ”, one teaspoonful of “ Ostermilk ” and a drop of “ Haliborange ” with boiling water to make a sloppy mixture which can be fed to the chicks with an eye dropper. After a little practice the technique of administering the food straight into the crop becomes very simple. Birds more than 10 days old need J. R. HODGES — THE BLUE- WINGED GRASS PARRAICEET 51 feeding every four hours or so and the amount of food given should be gauged so that the crop is not quite empty when the time comes for the next feed. When they are about four weeks old the youngsters begin to exercise their wings and to take short flights when they are waiting for their turn to be fed. At this stage they should be transferred to an ordinary box cage with the floor covered with grit, canary seed and millet sprays. They very quickly learn to shell seed and show their indepen¬ dence by refusing further hand feeding. Hand-reared birds make good specimens and, contrary to popular belief, excellent parents. In my experience Blue-wings are the most robust of the Grass Parra- keets. Mine are kept outdoors in unheated aviaries all the year round and are never locked in their shelters at night. During cold damp weather I have occasionally found an odd bird looking unwell, producing green, very liquid excreta, suffering from enteritis. Such patients respond miraculously to heat. They should be transferred to a hospital cage and kept on a plain seed diet at a temperature of 85 °F. until the excreta becomes normal. The temperature may then be gradually reduced over a period of one or two days. They can safely be transferred to the outdoor aviary again when the weather conditions are favourable. Although I have lost several Splendid Parrakeets from the same range of aviaries as the Blue- wings from infestation with Ascaridia, I have only once discovered the presence of round worms in the intestine of a dead Blue-wing. However, it is dangerous to be complacent about this avicultural scourge and I believe that all parrakeet breeders should use one of the non-toxic anthelminthics such as Tetramisole (Nilverm, I.C.I.) prophylactically at least. But our knowledge of diseases in birds is very limited indeed and probably the only really effective form of treatment for most bird ailments is heat. I think it is significant that I have had to use a hospital cage considerably less frequently for the Blue- wings than for any other species of parrakeet which I have kept. Until comparatively recently Blue-winged Grass Parrakeets were rare and expensive in Europe. Like Splendids, Turquoisines and Elegants they have almost suddenly become readily available in this country mainly because of the importation of large numbers of Continental bred specimens. Many of these are bred in cages and indoor aviaries. They are not as robust as outdoor bred specimens as many purchasers have found to their cost. Some of this continental bred stock is giving the Grass Parrakeets again a reputation quite undeserved, for being delicate. Outdoor aviary bred stock is certainly not. Keeping and breeding the members of the genus Neophema , particularly the Blue-winged Grass Parrakeet, has given me a great deal of interest and pleasure for more than a decade. Now that aviary bred strains are well established I am sure they will give as much pleasure to many others. 52 S. P. JOHNSTONE — WATERFOWL EGGS WATERFOWL EGGS By S. T. Johnstone (The Wildfowl Trust, Slimbridge, Gloucestershire, England) Egg identification in the Anatidae is extremely difficult, not only within the family and tribes, but also within a species itself where considerable variation can be found in colour, size and shape. The Magpie Goose lays a large white egg, the shell of which is thick and pitted. The Whistling Ducks all have white thick-shelled eggs of characteristic shape. Among the swans, the Mute and Black lay green eggs, the rest of the forms large white ones of similar size and shape and shell texture. The exception is the Coscoroba, which of course is considerably smaller. All the Grey geese produce white eggs which apart from the Greylag vary little in size. Even the Lesser Whitefront lays a comparative large egg for the bird. Among the Black geese, in the numerous races of Canada Goose, they are white and of similar shape, varying in size from maxima to minima. The Barnacle and Ne-ne eggs are indistinguishable from most of those of the Canadas. The Brents are smaller, as indeed are Red-breasted Goose eggs, which are also cream in colour. The Sheldgeese and duck eggs remain fairly consistent in colour and size according to the species. They mostly have thin creamy coloured shells. In the duck world is the greatest variation. Colour changes from the deep brown of the White-backed Duck through various shades of stone, buff, cream and green to the beautiful eau-de-nil eggs of the Barrow’s Goldeneye. Size differs from the goose sized eggs of the Steamer Ducks and Eiders to those of the Hottentot Teal. Difference in the size and colour in a particular species of duck has been most noticeable with the Shoveler, Gadwall and Wigeon. The following chart gives details of all forms of waterfowl eggs that have been available at Slimbridge. In most cases a large number of eggs has been examined, in a few instances only a single clutch has been measured.

T. HOLYOAK AND MISS D. M. SAGER — OBSERVATIONS 56 OBSERVATIONS ON CAPTIVE TASMANIAN NATIVE HENS & THEIR INTERACTIONS WITH WILD MOORHENS By D. T. Holyoak and Deirdre Sager (London, England) Ridpath (1964 and unpublished) has made extensive behaviour studies on the Tasmanian Native Hen ( Tribonyx mortieri) in Tasmania. This note records observations on the interactions of a single captive pair of Native Hens with several pairs of wild Moorhens ( Gallinula chloropus ) at the London Zoo. The Native Hen is a flightless, chicken-sized rail with dull olive-green plumage relieved only by a white streak on each flank. This species is restricted to Tasmania; an area from which moorhens of the genus Gallinula are absent. At the London Zoo the pair of Native Hens are kept on the “ Three Islands Pond ” ; they roam freely about the pond area and the surrounding lawns and flower beds, normally walking, but sometimes swimming buoyantly or running. They have succeeded in rearing only one chick so far, although they made several nesting attempts in 1969. Two or three pairs of wild Moorhens breed on the pond, taking advantage of the food provided for pinioned ducks and geese. The Moorhens raise several broods of young each year. The Native Hens defend land territories from the Moorhens, partly by chasing them, and partly by giving loud, harsh, two-syllabled aggressive calls; this call is a duet, the female providing a lower-pitched note than the male (this “ duetting ” was first noted by Ridpath 1964). Probably because of aggression from the Native Hens, the Moorhens defend only water territories from other Moorhen pairs. The Moorhens regularly give their turning away territorial display showing off the white under-tail coverts, both to other Moorhens and to the Native Hens, although the Native Hens enter the water freely when moving between the islands in the pond. This division of the pond area into land territories for the Native Hens, and water territories for the Moorhens is very clearly marked. Often a Native Hen will run ten yards to chase a Moorhen into the water, then ignore it even though it is swimming only two or three feet away with the white under-tail coverts fluffed. Because of this, the Native Hens are defending three islands and parts of the land surrounding the pond from Moorhens, but within this area two or three pairs of Moor¬ hens are defending water territories between themselves. In June 1968 three Moorhen chicks a day or two old (smaller than a chicken’s egg) were watched as they were fed first on land by the pair of Native Hens, then in the water by a pair of Moorhens which we assumed to be their parents. Both pairs of birds showed considerable interest in the chicks, although the chicks appeared to be more strongly attracted to D. T. HOLYOAK AND MISS D. M. SAGER — OBSERVATIONS 57 the Moorhens. The chicks seemed to be reluctant to enter the water, and the Moorhens were unable to visit the chicks freely on land because of aggression from the Native Hens. During one two-hour period of watching, the chicks were fed several dozen times by both the Moorhens and the Native Hens. On land both species fed the chicks on small pieces bitten from grass leaves; in the water the Moorhens picked tiny objects (possibly insects) from the water surface. The Moorhens made frequent attempts to approach the chicks when they were on land, but they were usually driven back into the water by one or other of the Native Hens. However, the Moorhens reached the chicks a number of times, and each time the behaviour of the Native Hens towards the Moorhens was completely different when the Moorhens were either feeding the chicks or very close to them. Instead of chasing the Moorhens away, the Native Hens maintained a passive indifference a few feet away. Nevertheless, as soon as the Moorhen moved more than a few feet away from the chicks it would be chased back into the water and sometimes savagely pecked. This “ cutting off ” of the aggression from the Native Hens when the Moorhens managed to approach the chicks closely was striking. Two explanations of the behaviour seem reasonable; first aggression near the chicks may be greatly reduced because of the danger of causing injury to the chicks in birds which are as aggressive as rails (the danger of injury might be mainly from redirected aggression; the selective value of reducing this near to chicks could be greater than that involved in reducing the risk of accidental injuries), and secondly (as suggested to us by Derek Goodwin) in natural situations there may be little point in attacking a strange bird when it has reached chicks, as its ability to eat them would then seem to be assured ; attacking the predator at this stage might be dis¬ advantageous because of the risk of injury to the adult birds. Derek Goodwin has seen analogous behaviour in Song Thrushes, Turdus philomelos, whose nest was being robbed by a Jay, Garrulus glandarius. Here, the cutting off of aggression can probably best be explained by the second of the two alternatives mentioned above. We are grateful to Peter Olney for help in studying birds at the Regent’s Park Zoo, and to Derek Goodwin for helpful suggestions and encourage¬ ment. REFERENCE Ridpath, M. G. 1964.

Thomson (Hoole, Cheshire, England) Visitors to my aviary frequently express interest in the use of nylon netting. On the other hand the material is occasionally condemned by a few who may have used it under unfavourable conditions. While nylon netting is no substitute for wire netting, it has its use in aviculture. Where quail, partridge and pheasant stock is housed, nylon covered enclosures minimize head injuries which may occur when birds suddenly rise up in flight. Young waterfowl and pheasants can be protected from winged predators by temporarily covering their open pens with netting. Here it is also used to cover extensive enclosures in which various research projects are undertaken. Normal practice is to cover an enclosure for 9 months of the year, removing the netting for the winter. Nylon netting, being so light in weight, can be used to cover very large areas by the use of a few cross wires. It is not subject to temperature changes 01 frost, but like all other synthetic netting is liable to damage from the ultra-violet rays of the sun, and for this reason it is necessary to treat it every year or so. It is quite a simple process to bundle the netting in a bale by tying it up with twine, the neater the mass is compacted the easier the next stage, which is simply dipping it in whatever preparation is being used. The net-makers recommend black tar or bitumen. A creosote and bitumen mixture acts very well. This dipping process can be carried out in a bath, drum or any handy container, the treated netting being left to become drip dry. The object of such treatment is to dye the netting a dark colour, this being necessary when it is being used out of doors. The breaking strains of the twines from which the nylon netting is made are very high. The netting is sold in several grades, according to the number of twines used. Complete nets of any size are made to mea¬ sure, where rectangular measurements are given. There is a wide range of mesh sizes and the netting sets squarely without any stretching. It is an advantage to have the netting corded on all sides at an extra cost of a few pence. All twine nettings are subject to abrasion and although nylon is very strong it will gradually rub through on wires or other supports if there is any undue movement. It is therefore very necessary to see that the nets are securely tied down in order to prevent as much move¬ ment as possible. This has not always been carried out here and nets have suffered by the wind creating a continuous rippling wave action, resulting in netting fatigue, especially at the edges where it was secured. One system tried out here could be called the suspension method. Wires were strung across a 60 ft. x 60 ft. unit at about 3 ft. intervals from north to south and east to west, giving a criss-cross pattern. Ex W.D. telephone wire was used. The netting was laid on top and secured T. S. THOMSON — NYLON NETTING 59 around the sides by using 3 ft. long, 1 in. x J in. strips of wood nailed to the surrounding framework. Wires were strung from the apex of an adjacent roof running parallel to one side of the unit and across to the other side (see sketch). Ties from the suspension wires were made to the criss-cross wires on which the net lay. It was thus possible to suspend the complete net from above, the absence of ground supports being desir¬ able since mechanical cultivators were used to till the soil. While this method proved satisfactory it took some time to set up and there was trouble removing the net, there being so many ties to undo. Also there was some chafing of the netting where the vertical ties made contact. The following season one central pole, placed in a few minutes, did away with the suspension idea. Where one central pole is used it is necessary to fix the cross wires which come in contact with it underneath all other wires in order that all other wires are raised when the pole is placed in position. Rats occasionally try to establish themselves in the area and can be very destructive to nylon netting. The pests run up the surrounding woodwork, bite a hole in the netting and gain access to the aviary. Fre¬ quent visits results in the netting being destroyed. To overcome this a perimeter of wire netting was fixed around all sides of the aviary. The perimeter is a 1-3 ft. width of wire netting forming the edge of the aviary roof and attached to the top edge of the side walls, projecting inwards and suppoited below by horizontal or slanting wood supports. The nylon netting which forms the main part of the roof of the flight is attached to the inner edges of this wire netting, with a small overlap. If the flight is not built on to anothei flight or shelter there is some advantage in allowing the wire netting perimeter to project outwards around the top edge of the aviary for about 6 in. This acts as a barrier to cats and similar predators. This proved 100% successful. In addition, with frequent use the edges of nets became frayed and by the use of the wire netting perimeter nets were given a new lease of life. The wire netting surround also prevented cats from gaining access to enclosures when the nylon netting was removed for liberty experiments. Some cheap grades of nylon netting can be torn by Tawny Owls striking at birds in aviaries. 6o T. S. THOMSON — NYLON NETTING When fixing on a large net it is first taken to a neighbouring field, pegged out, the corners marked and the net rolled up in one long strip and then folded up for easy carriage. Taking the wind direction into account, the netting is unfolded along one side of the aviary and made secure. It is then unrolled, the wind being a great help. When netting is removed it is usual practice to mark the corners with some ties and again make full use of the wind. A soft broom is also used to piod upwards at the netting in order that it be rolled or folded to one side. The net-makers do not state how long nets last as this very much depends on the prevailing local weather conditions during the time that they are in use. Nylon netting is not intended as a permanent cover for aviaries but is primarily used during the breeding season. However, in order to put it to some sort of test a square yard was permanently fixed over a safety door entrance. The net of f in. mesh made up of the cheapest quality one strand netting withstood 6J in. of snow. The netting sold as aviaiy quality is several times stronger, in fact it can support a man grasping with one hand. It is, of course, several times the price. The cheapest grade of nylon netting costs less than wire netting of the same mesh, while the top grade of nylon is more expensive. While we do seem to receive sufficient sunlight to affect nylon nets in this country, snow presents the biggest problem. Aviaries are flimsy structures and where nylon is employed this is even more so the case. Tests were carried out by leaving a 50 ft. x 50 ft. unit cover by nylon all the winter. Result, total collapse after a 6J in. fall of snow. The structure withstood 3 in. and 4 in. falls. It was the surrounding framework and the cross wires which fractured, bringing the netting down over trees enclosed in the aviary. The netting was extensively torn. The total weight of snow was calculated at over 3 tons, assuming 1 in. of rain is equivalent to 1 ft. of fresh snow and one cubic foot of water weighs 62J lbs. Where the perimeter wire netting is fixed it has been found unnecessary to remove members of the pheasant family when the nylon roof was removed. While nylon netting has never been fixed here in the vertical position, reports have been received of birds being caught up under such conditions. M. D. ENGLAND— THE RUFOUS-BACKED SHRIKE 6l THE RUFOUS-BACKED SHRIKE ( Lanius schach) By M. D. England (Neatishead, Norfolk, England) The following most unscientific — not to say sentimental — notes were prepared for publication before the interesting and informative article by Herr Reinhard Hoppe appeared in print (Avicultural Magazine 5, 75, 1969, 161-164). Since there is so much that he says with which I agree — though not all, which is hardly surprising — and the case-history of the one bird which I have recorded here bears out so well some of the points which he makes, I have amended slightly what I have written so as to emphasize points of agreement and disagreement. I feel sure that what both he and I have written will, at the very least, cause a lifting of the eye¬ brows of both the “ for and against mealworm ” brigades, but this will be all to the good if future aviculturists benefit from our experiences. On the question of mealworms, may I say at once that I am very much on the side of the “ ayes ”, and that I use them almost exclusively for hand-rearing. My wife and I have hand-reared, from the small nestling stage, Hoopoes Upupa epops , Rollers Coracius garrulus, Black-eared Wheatears Oenanthe hispanica , Rufous Bush-chats Agrobates galactotes , Woodchat Shrikes Lanius senator , among many other species, on practically nothing else, most of the birds living to a ripe old age. The Black-eared Wheatears bred at seven years old (for the first time, having fought bitterly until then!) and one of the Rollers is now at Birdland, Bourton-on-the- Water, hale and hearty in his tenth year. I am sure that it is most important to remember that all these birds had “ a good dietetic start ”, in that they were fed on natural food by their parents until about ten days old, a quite different matter from being fed only on mealworms from hatching. May I hasten to add that I know that many outstanding first- breedings have been achieved on mealworms alone but, however much I favour them, I think it fair comment to say that it is probable that in such cases success has been despite the mealworms and not because of them! It may be of interest to note here that Great Grey Shrikes Lanius excubitor , though eating mealworms with relish and disgorging pellets which contain only the skin, heads, and claws, do not eat maggots readily and seem quite unable to digest them, bringing up a mass of whole maggots shortly after swallowing them. On the other hand, they eat blow-fly pupae and the resulting pellets contain the cases only. My pair killed off two broods of their nestling by giving them nothing but these. The young could not digest the cases and were not old enough to regurgitate pellets. As a result, post-mortem examination showed death to be due to an impacted mass of blow-fly pupal cases. I shall take good care that the parents do not have access to them again during the breeding season. 62 M. D. ENGLAND — THE RUFOUS-BACKED SHRIKE I obtained my Rufous-backed Shrikes by mistake. A year or two before, the female of my pair of Bay-backed Shrikes Lanius vittatus had died, and all my efforts to find a replacement had failed. They are such lovely little shrikes, with most intriguing ways, that I thought I would make one last attempt by accepting responsibility for a whole consignment from India of up to a dozen, in the hope that there would be an odd female among them. Dealers tell me that they do not like shrikes since they are often difficult to sell. I cannot understand why, because it would be hard to find a family of birds which is more rewarding in captivity and with such interesting habits. In due course a telephone message told me that ten had arrived “ but only seven are alive this morning ”. This was not surprising, since all ten had been put together in a large cage. Few birds are more murderously territorial, and out of the breeding season those at the lower end of the pecking order, if they escape death by violence, would meet it by starva¬ tion. I was also told that “ there didn’t seem to be any Bay-backed among them ” ! My unprintable reply to the effect that, whatever species they were, they must immediately be separated was, I am thankful to say, acted upon but I was in a quandary because, since I work in a hospital, I was not going to be able to get home until Friday night at the earliest and this was only Tuesday. John Yealland very kindly came to the rescue by offering to look after them all pending sorting out. Of the original ten birds, four had been Great Grey Shrikes Lanius excubitor and six Rufous-backed Lanius Schach. There now remained two grey and five of the others, one of the latter looking very seedy indeed. On the Friday night I made a start by taking home the two greys, followed a week later by two of the Rufous-backed. The choice of a “ pair ” was by sheer guesswork because sexual plumage differences in the latter species, if any, require a more discerning eye than mine. They were put in a divided cage with a wire partition, which was a mistake because next morning both had their faces covered in blood. Cardboard reinforcement to the partition lasted only a very short time before they managed to “ get at ” each other, so they were soon moved to adjacent small flights in a bird-room. These are little more than large cages, with a floor area of less than three feet square. Although they could, of course, see each other, fighting stopped and they ignored each other completely. The normal daily feed for the pair, except when feeding young, consists of about 25 mealworms, and/or 30 or more maggots, locusts and wasps as available, and about half an ounce of lean ox-heart chopped up small and rolled in soft-food, Vionate, powdered cuttle, yeast powder and occasion¬ ally powdered baby food. I had no spare aviaries and, if I thought about it at all, I dismissed all thoughts of breeding until next year. Indeed, one day I found one of them sitting on the window ledge looking very sick. I was just turning away to reach for an infra-red lamp when I saw her do a little “ shuffle ” : she Avicult. Mag. Fig. i. Juvenile Rufous-backed Shrike Lanius schach, 28 days old.

ENGLAND — THE RUFOUS-BACKED SHRIKE 63 was not sick but “ broody A handful of dry grass proved it, for she immediately flew down and, gathering an immense beakful, started looking for a site in her very bare quarters. I hastily fixed up a bundle of twigs and a rolled-up piece of wire netting, and within a couple of hours the latter had a nest in it. Meanwhile the other bird next door had taken no notice at all. I thought that at least I might get some indication of its sex if I put it in with the other, so, prepared for murder, I opened the communicating door. Within a very short while another nest had been built in the bundle of twigs. Two hens! By this time John Yealland’s place had been taken by Peter Olney and I quickly arranged to try the other shrikes one at a time until one gave signs that it was a male. However, by the following weekend and before I could do this, one of the first pair was incubating three eggs in the nest in the wire and was being fed by the other bird. No signs of courtship or mating were seen and, although by now we were calling the sitting one “ she ”, the sex of the other was still in some doubt because, while it certainly occasionally fed the sitting bird, it continued to add to the other nest in a desultory way. A fortnight later doubts were dispelled by the sitting bird, on receipt of a mealworm from the other, rising and passing it on to something beneath it, and when I cautiously put my head in the door to feed them I received a sharp blow on the nose from an enraged dive-bomber. (Although he never attacked my wife, he always came screaming down at me. When, later on, I wanted to examine the nest I must have looked pretty silly climbing in the door with a hat on!) No parents could have tended their young more carefully, though they refused to feed them with anything but mealworms, despite the fact that they themselves were used to a mixed diet. Every possible alternative was tried, but they starved the young rather than give them any other kind of food. Even mealworms with the slightest touch of Abidec, Vionate or yeast powder were not touched, or only eaten by the parents. At the end of a fortnight it was apparent that all was not well, because the female was still brooding most of the time and no gaping beaks were visible when either she or her mate carried food to the nest. When they began bringing the food away from the nest uneaten, I decided that I must investigate. The enraged parents were shut away while I miserably removed two fully-feathered but moribund youngsters. One was very dead indeed, but the other had a faint spark of life. Its open beak was crammed with putrefying food, it lay limp in my hand and it had not the strength even to lift its head. Its eyes were closed, it lay on its side, and its toes were deformed and in what, had it been human, would have been described as a “ talipes equino varus ” position. Every now and then its whole body was racked by a violent spasm. Poor little mite, the kind thing would have been to put it out of its misery. But a Rufous-backed Shrike . . . and what an exercise in hand- rearing ! 64 M. D. ENGLAND — THE RUFOUS-BACKED SHRIKE It is one thing to hand-rear a young bird which is healthy and has had a natural start from a nutritional point of view; quite another in circum¬ stances such as these, where the most optimistic diagnosis was polyneuritis with paralysis and possibly also rickets, almost certainly resulting from a dietary deficiency. He (it quickly became “ George ” — even my violent dislike of anthropomorphism could not resist this) was wrapped in a cloth, with a thermometer beside him, and put under a “ non-luminous ” lamp set to maintain about ioo°F. The food-stuffed bill was cleaned up and he was left for an hour. To our great relief he had defaecated, and thereafter his bed was lined with a frequently-changed piece of toilet paper. Force-feeding began, with chopped-up mealworms treated with Cytacon, Abidec or cod-liver oil and dipped in Meritene (a well-balanced baby and invalid food manufactured in Portugal under licence from the D. H. Doyle Pharmaceutical Company). Later he was forced to consume large quantities of Vionate. At first it was difficult to get the food down, because paralysis had affected swallowing and the little tongue hung out to one side of the bill. But soon he began feebly to gape, his eyes opened — though one appeared to be sightless — and as each succeeding morning found him still alive we began to realise that our belief that he was improving was not just wishful thinking. He could raise his head when he gaped, swallowing became less and less of an effort, he even tried to lift himself on his poor little crippled feet. At a month old he was trying to grip with the toes of one foot, he looked around alertly with both eyes, and he called incessantly for food. It looked as though we were really winning. By now he ruled the whole household. And then, tragedy! One evening before being closed down for the night he was enjoying his usual freedom of the room, flying from shoulder to shoulder, when one of our dogs nosed open the door and, although it made no aggressive movement, George took fright. He flew to the only place where he could hurt himself — the slightly-open door of a cupboard where he caught his head in the crack and fell to the floor unmoving and apparently dead. With a heavy heart I picked up the little body. There seemed no doubt this time. And yet there was the faintest pulse, though he was completely unconscious. Once more the cloth bed and heat, though this time with no hope at all. At the crack of dawn I went sadly to look. There he lay, eyes closed, head sagging, bill slightly open — but alive. It was not a question of “ going back to square one ” — we were further back than when we started. But once more — heat, force-feeding, gross over-doses of everything we knew; the blindness, the paralysis, the useless toes, the poor lolling tongue. And once more George slowly came back. He is now, in early January, nearly six months old. He lives in a cage though he prefers to be out of it, flying from shoulder to shoulder and exploring the room. He can, of course, feed himself perfectly well, though he shouts continually to be fed, or perhaps for a game or a ride on M. D. ENGLAND — THE RUFOUS-BACKED SHRIKE 65 our hand. He grips a perch with both feet, though one will never be much good to him. During his freedom of the room, he finds it easier to hang from the curtains than to perch on slippery furniture. When we are too busy to do more than put his food in the cage and he feels neglected, he gets in a rage and, after a period of shouting, he tears up the newspaper in his cage and fills the water pot with it or pokes it through the wire so that it floats all over the floor of the room. He also violently pecks the first outstretched hand. By 30th October (at nearly fifteen weeks old) adult plumage had been assumed except for some very faint brown barring of the flanks. This is much quicker than any record of which I am aware for any other species of shrike. For some time it was assumed to be female because, whenever I approached closely or put out a hand to pick her up, she “ crouched ” in what looked like an invitatory posture, to me, her supranormal mate. However, I now know that I was wiong about this, since this posture is the means whereby the parents resolve a squabble or fight. The dominant bird, though obviously still “raring to go”, desists when its opponent crouches, head right down pointing at the floor, in submission. I only hope they will continue to settle their differences in this way, since I simply cannot spare separate aviaries for them. Directly he was able to move about his cage he began trying to impale or wedge his food. Although various species of shrikes have been hand-reared before and it seems unlikely that they learned impaling from seeing it done by their parents, it is probable that this is the first occasion when a youngster which was blind on removal from its parents has impaled immediately it was strong enough to do so, thus showing conclusively that the action is innate. In the same context it is worthy of note that his warning notes and song are normal although he cannot possibly have heard any of his own species since he was a fortnight old. It may be of interest to add that, in addition to food, he impales pieces of newspaper. He is now no longer as tame as he was, since we have less time to devote to him, and when his cage is approached in such a way that he cannot see that the approaching person is one with whom he is familiar, he performs bill-snapping, similar to that done by owls in like circumstances. Since I am away from home at least three days and nights each week, the credit, if any, goes largely to my wife, who devoted herself to yet another foundling with an unshakable determination that he should live.

HANOVER — DILUTE FORM OF THE KEY-WEST QUAIL DOVE A DILUTE FORM OF THE KEY-WEST QUAIL DOVE By Donald G. Hanover (Tarzana, California, U.S.A.) Keeping and breeding foreign doves and pigeons is a hobby that poses many problems and difficulties. Especially true is this when it comes to the rarer varieties of foreign doves and pigeons, concerning whose living habits in the wild we know but very little. Take the Key-West Quail Dove, for example, that handsome, gentle, almost pigeon-sized bird, which made its debut in this country not many years ago, and which today is found in limited numbers in a few fanciers’ aviaries. These doves are mainly chestnut-brown above and duller brown on the wings, with extensive irridescence of green and purple, not only on the top of the head and neck but also over most of the back. The sides of the head are dark brown with a conspicuous white streak below the eye; and the throat is white. The underside is mauvish-grey, browner on the flanks and whiter on the belly. I happen to be one of the fortunate owners of several pairs of Key-West Quail Doves, Geotrygon chrysia , which have been living, and modestly breeding, in my aviaries now for several years. All of them, without exception, are descended from the first pair, there having been no fresh imports of this very interesting, beautiful dove in recent years. In other words, the offspring produced is the result of in-breeding, of mating closely related members of one family with one another. On rare occasions such matings will bring forth surprisingly strange colour patterns, which in no wise resemble the plumage colour of the parent bird. Well, I am happy to report such a radical colour variation, namely a dilute form of Key-West Quail Dove, which is, in all probability, the only representative of this variant. The breast and under parts are almost white, the head, neck, back, wings, and tail are an off-white, and when closely examined are very pale buff and light grey. All the colouring is considerably reduced and the iridescence disappears. The eyes are a very bright, sharp red. At this writing the bird is nearly full grown, to all appearances lively and vigorous. In shape and form, and habit, it is and acts like a normal Key- West Quail Dove. To date its actions have not as yet revealed its sex. Depending on it, I plan to mate this unique dove back to its male or female parent in the hope of getting another dilute, or near dilute specimen, which together I might utilize to produce a strain or family of variant Key-West Quail Doves. Needless to say, I am both surprised and delighted with this happy event, and I hope to report in the future on the breeding results from this dilute Key- West Quail Dove. Some years ago, there was a request from a conservation group in Key- West, Florida, hoping to purchase a few doves for restocking. It is Avicult. Mag, Normal Key-West Quail Dove.

Smyth (Manley, New South Wales, Australia) I recently returned from Papua-New Guinea after spending almost two years there, mainly in the Southern Highlands District, where I spent most of my leisure time birdwatching, though I did manage to keep a few birds in cages for short periods, so perhaps a few notes may be of interest. Without doubt the most interesting members of my small collection were a Blue Bird of Paradise Paradisaea rudolphi and a Lawes’ six-plumed Bird of Paradise Parotia lawesi , purchased as fledglings at Tari markets. Market days are held twice weekly at Tari where the natives offer a wide range of locally produced produce, and occasionally birds, too, are offered for sale and with the possible exception of parrots, most birds I have seen for sale at the markets have been quite young and unable to feed themselves. I was first aware that fledgling Birds of Paradise could be bought, when a friend asked me to identify a bird offered to him by a local Tari boy. It was quite clearly a Blue Bird of Paradise, not long out of the nest and though it looked healthy and gaped readily it made no attempt to fly, but sat in the boy’s open hand in such a relaxed way that I believed it to have been hand-reared. Regulations concerning the keeping of Birds of Paradise within the territory are quite definite so my friend was reluctant to buy, but after being assured by his house boy, who was acting as interpreter, that the blue bird, if not sold, would surely be eaten, he paid the twenty cents asked. Unfortunately this bird died after a few days and I suspect that like birds subsequently bought by me it had been disabled, prior to capture, by being hit by a stick or stone thrown by the boys, who are surprisingly accurate. On 13th July 1968 I bought at the market a young Lawes’ six-plumed Parotia which had an injured leg but otherwise appeared healthy, and it also gaped readily. Insects and fruit seemed a reasonable guess as to its food requirements, and after a worrying first few days the youngster settled down to a diet of insects, mostly cicadas and moths attracted to the lights at night, and paw-paw and bananas mashed together with powdered milk. Mashed 68 H. SMYTH — HAND-REARING AND OBSERVING BIRDS OF PARADISE paw-paw and powdered milk later proved to be more satisfactory, for if allowed to stand for an hour or more this mush becomes quite firm, is enjoyed by the birds, does not soil the feathers to any great extent and droppings are much firmer than when banana is added, again reducing the risk of fouled plumage. On 31st August I acquired, for 20 cents, a beautiful young Blue Bird of Paradise, similar to the one mentioned previously, though much brighter in colour but unfortunately more knocked about than the previous bird. Again, after a very shaky start, it began to do well but later sloughed two toes which were broken when I bought it. Both birds became very tame and when anyone approached crouched down on the perch, gaped widely and with quivering wings begged for food. The Blue Bird made quite a feature of wing quivering and continued to do so up until the time I disposed of it at about five months old. I suspect this is a habit of the species, for when visiting Tari at a later date, February 1969, I was resting in a thick patch of forest when a young fully grown Blue Bird perched quite close to me. This bird, though not in full colour, had lost most of its juvenile plumage and had blue in the lesser wing coverts. Whilst studying it through my binoculars I was surprised to see a handsome bird, presumably its mother, alight alongside it. The young bird went through all the previously described begging motions, though it was fully as big as its parent and the older bird proceeded to feed it five small black berries, probably stored in its throat or beak, since it made no display of regurgitation as would a pigeon. Both birds sat together for a while and a striking difference was the size of the adult’s beak as compared with the younger bird. The pale grey colour of the adult beak may have helped give an impression of greater size and though perhaps no longer, I feel sure its other dimensions were considerably larger. The Lawes’ six-plumed in juvenile plumage resembles the mature hen, with black head and brown body, underparts barred with darker brown. These brown birds, with occasional fully coloured males, could often be seen feeding in berry-bearing trees near native gardens and in timbered areas. One peculiarity of the young bird is two tufts of feathers on its head, probably in the position where the plumes normally grow. These small tufts stand about a quarter of an inch above the other head feathers but are only noticeable when the bird erects all its head feathers, as it occasionally does. What prompts the young bird to do this I am unable to say for sure, but suspect it to be an attempt at display, though I have seen the head feathers raised when a large bird flew past, but fright will not always bring this reaction. H. SMYTH — HAND-REARING AND OBSERVING BIRDS OF PARADISE 69 In October 1968 I returned to Sydney and left my birds with a friend at Kagua, where they were housed in a mixed collection, including tree kangaroos, wallabies and cuscus. It was late in November when we were reunited at Mendi and the change the separation had brought was surprising, particularly in the Parotia, which was extremely fit and aggressive and attacked me savagely whenever I put my arm in the cage. I was forced to separate the birds since the Blue Bird looked so shabby as compared to its companion whose feathers, though still coloured like the female, were quite glossy. The Blue Bird was still friendly and confiding and as mentioned previously begged for titbits and with a little extra care was soon back to normal. Feeding was something of a problem since Mendi is cooler than other stations of similar altitude, and many fruits, such as paw-paw are not available, but both birds proved themselves adaptable and ate, reluctantly at times, tinned fruit, raisins, tomatoes, minced steak and even fish. However, the food position was not entirely satisfactory and when at the end of December 1968 I learned that a friend was going to visit the Baiyer River sanctuary I asked him to take both birds along to Fred Shaw- Mayer, who was then in charge. Birds of Paradise appear hardy and are certainly easier to hand-rear than many common birds here in Australia. I think the diet I gave them was not quite adequate since neither bird flew well. However, I could not detect anything wrong with their wings. The Lawes’ six-plume and the Superb are perhaps the most common of the Birds of Paradise in the Southern Highlands area. Though more secretive and less noisy than the Superb, they, the Lawes’ six-plume, are reasonably numerous both in heavily timbered country and more open areas and do not appear at higher altitudes than about 6,000 ft. They are often heard and less often seen as one walks along native tracks in timbered areas and keeping low in dense cover the birds utter their harsh call and appear at times to follow one for short distances. Playgrounds belonging to this species are fairly easy to find in most areas and at Tari, within half a mile of the council house, in a few acres of heavy timber, adjacent to native gardens I spent some time observing and trying to photograph both Lawes’ six-plumed and Blue Birds of Paradise. There were two playgrounds in this area within a few yards of one another and whenever one approached closely, no matter from what direction, the Parotid's harsh cry would ring out and usually a fully coloured male would be seen for a moment. On one occasion, five birds, including the adult male, came on my approach and stayed close by for a while. Four were of similar colour 70 H. SMYTH — HAND-REARING AND OBSERVING BIRDS OF PARADISE to the female, though one had plumes. I had seen this bird on more than one occasion and believe its head feathers to be more glossy than the others. Both cleared areas were roughly of the same area (about 40 to 50 square feet). One roughly oval and the other very irregular, and I saw no evidence of decoration on either. Each had a horizontal or near horizontal branch close by and within 5 ft. of the ground. These branches appeared much used and how they came to be bent over in such a way I am unable to say, obviously too strong for these birds to bend, I suspect it is the presence of a horizontal stick which influences the choice of play area. The Blue Birds of Paradise which often share this patch of timber were usually easy to find, since their call is so characteristic and loud. At a distance it reminds me of the clang of hammer on steel, but oi^l closer approach this resemblance does not hold, however the call is quite loud and distinctive. At close quarters and in dense undergrowth one can often be guided to the Blue Bird by his habit of mumbling (as though talking to itself) during preening and partial display, and by following this call I have come within a few yards of a splendid male, displaying upside down, less than 6 ft. from the ground, but surrounded by heavy undergrowth. Although obvious of my presence and keeping a watchful eye on me, this bird continued to display for at least a minute. Though these Blue Birds eat fruit, I have never seen them feeding with other species but have often watched them hopping along moss-covered branches probing about for insects and on one occasion I saw a well- plumed male bird moving up the trunk of a dead tree in the manner of a tree creeper. The accompanying photograph of the playground of Lawes’ six-plumed Bird of Paradise was taken at Karoba about 25 miles from Tari. Despite its rather untidy appearance I think this one was still in use since it was the warning calls of the bird which caused me to investigate the area. Most playgrounds, though generally similar to the one pictured, are kept very clean and free from fallen leaves, etc. Because of the much heavier timber growth and consequent poor light, the other playgrounds mentioned could not satisfactorily be photographed. J. DELACOUR — BRAZILIAN BIRD COLLECTIONS 71 BRAZILIAN BIRD COLLECTIONS By J. Delacour (Cleres, France) Once again I had the pleasure of visiting Brazil in November 1969, spending a couple of weeks with my friend Dr. E. P. Beraut near Rio de Janeiro. His collection of tropical birds and plants looked better than ever. Gardening and bird-keeping in a warm country are particularly rewarding — there is very little trouble caused by the climate, although the most delicate species should be well sheltered from winds during the cooler season, and you can enjoy your collections outdoors every month of the year. Dr. Beraut’s garden is large and hilly, situated at the foot of a rocky mountain, close to two others (Gavea and Tijuca) and also to the ocean. It looks like a huge conservatory, as the plants are those seen in the hot-houses of botanical gardens, but, of course, grown on a much bigger scale. The trees are overloaded with orchids, bromeliads and other epiphytes. There is a rushing torrent over rocks and several pools. A few Trumpeters, Demoiselles, Crowned Cranes, Scarlet Ibises, Roseate Spoonbills and Egrets have the run of the grounds, and wild birds are numerous on the trees and bushes, the commonest of which are the Tricolored Tanager and several species of Hummingbirds. Dozens of them are always buzzing around the verandah where bottles of nectar are kept ready for them. The most numerous are the Dusky Jacobine (Melanotrochilus fuscus) and the Blue-headed Wood-Nymph ( Thalurania glaucopis ), but Swallowtails ( Eupetomena macroura), Mangos (Anthracothorax nigricollis) and Brazilian Violet-ears ( Colibri serrirostris) also come to drink. A female Pigmy Hermit had a nest in a nearby bush, but she never sought the bottles. Although there are 25 aviaries, large and small, and more in the making, none can be seen when you walk through the grounds. All are built along the outer fences, sheltered by walls and hidden by shrubbery. With the exception of those occupied by parrots, all are heavily planted. Three of the flights are of large size and full of trees and plants. They are close together, but irregular in shape. A corridor divides two of them and gives access to a bird kitchen and to shelters where caged birds and hand-fed fledglings are kept. Nine compartments run along the back of the third aviary, and plans are made for making another dozen of those breeding accommodations, where pairs of birds are secluded. At present, they consist of several pairs of Eclectus Parrots, most of them reared there, some Toucanets, Motmots, Taccazze Sunbirds, Garnet-throated Hum¬ mingbirds, Blue and Golden-breasted Sugarbirds, Fairy Bluebirds, the latter with young. When pairs of birds are showing signs of nesting in the larger aviaries, they are quickly removed to the privacy of these breeding pens. The corridor is the home of a few pets — a Razorbill Curassow, a Sun Bittern and a Purple-capped Lory. 72 J. DELACOUR — BRAZILIAN BIRD COLLECTIONS The three large flights contain remarkable species of soft-billed Passerine birds, exotic as well as South American, of which it no doubt is the best collection existing today. The first one is inhabited by a pair of Umbrella Birds ( Cephalopterus penduliger ), and three male and two female Guianan Cock of the Rock (Rupicola rupicola). They are all tame, agree perfectly well, the male Cocks of the Rock displaying together. A Lesser Bird of Paradise has been there for eight years and is in superb plumage. A pair of Blue¬ winged Pittas and a Brazilian Ant-Pitta ( Grallaria varid) also live in peace as well as a few smaller birds: Golden-winged Sunbirds, a Waterton’s Wood-Nymph, and a few small Formicariidae, including the lovely Pithys albifrons , a small black and chestnut ant-catcher, with a crested white face of the most unusual appearance. I have seen long ago these curious birds following army ants in French Guiana whence Charles Cordier brought some to Cleres later on. Another large flight is the home of Central American and Golden¬ headed Quetzals, Scarlet Cocks of the Rock, a number of Cotingas : a lovely and tame Swallow-tailed {Phibalura flaviventris), a Bare-necked Fruitcrow (Gymnoderus foetidus) and a Black-necked Tityra {T. cay ana) ; a Swallow¬ winged Puff bird ( Chelidoptera tenebrosa), various Tanagers, Scarlet¬ chested Sunbirds; several small Hummingbirds ( Sericotes holosericeus , Augastes lumachellus, Stephanoxis lalandei); White-capped Redstarts ( Chimarrhornis ), Royal, Splendid, Amethyst Starlings, American Jacanas (nesting), different Plovers, etc. The largest aviary (about 35 ft. x 25 ft.), heavily planted, has a little winding river where Cotton Teal can swim; there are also Roulrouls and small Rails {Later alias leucopyrrhus ); but it is otherwise dedicated to small species. There are Sunbirds {N. pulchella ), Hummingbirds of several sorts, Paradise Tanagers, different Sugarbirds, Flowerpeckers ( Dicaeum ), African Paradise Flycatchers, a few Old World Robins, and Blue Cotingas. But most remarkable is the collection of Manakins, which live there in perfect condition and never quarrel: Pipra fascicauda, P. erythrocephala , P. rubrocapilla, P. pipra , P. serena, Manacus manacus , Chiroxiphia linearis , C. caudata , C. pareola, Elicura militarise Machaeropterus pyrocephalus, and the magnificent Antilophia galeata, a fairly large Manakin from the interior of Brazil (I found it common in Goias), black, with scarlet helmeted head and back. There are other groups of aviaries. Two good-sized ones contain pairs of African Pigmy Kingfishers, Irena’s Pittas, Jamaican Long- tailed Hummingbirds, Blue-and- White Indian Flycatchers and a few others. Five more are inhabited by Ross and White-headed Touracous, Short¬ tailed Antthrushes ( Chamaeza ), Gnateaters ( Conopophaga ), several species of small Rails, Roulrouls, etc. There are pairs of Leadbeater’s Cockatoos and Queen of Bavaria’s Conures in a large flight. The conures were laying in a log, but it is interesting to note that the Cockatoos, although in perfect J. DELACOUR — BRAZILIAN BIRD COLLECTIONS 73 condition, have never nested, probably due to the lack of a cold enough winter and of too much humidity. Elsewhere live several Toucanets ( Aulacorhynchus sulcatus , Pteroglossus heauharnaiesi , P. bitorquatus) a number of Hummingbirds, Sunbirds, and various small insect and fruit eaters. At the time of my visit, many nestlings collected very young in Dr. Beraut’s extensive land holdings at Tapirapuan, Mato Grosso, were being hand-raised. The most interesting ones were 16 Trogons of four species (T. strigilatus , melanurus , curucui , collaris ); Cotingas, Puff birds, Swallow Tanagers ( Tersina ) and 17 Jacamars ( Galbula ruficauda). These were in broods of three or four. Very small when I arrived, they grew up rapidly and were flying and perching within 10 or 12 days. Absurdly tame, they were fed every hour on small, soft pellets composed of one- third ground beef heart, one-third grated carrots, one-third maize cake (cooked). These highly insectivorous birds are perfectly raised on that diet, which they continue to eat when grown up. They live so well on it that they have attempted to nest, digging in an artificial bank. But they are quarrelsome birds, and the female injured the male. Adult-caught Jacamars always refuse any food but live mealworms and never lived long; Dr. Beraut hardly gives any to his Jacamars, mealworms being scarce in Brazil. There was also an excellent young Squirrel Cuckoo ( Piaya cay and) and a Nightjar, fed the same way as were the young Trogons. Because of various difficulties in procuring certain foods, all birds in Dr. Beraut’s aviaries receive that same meat-carrot-maize bread mixture, with diced cheese and for fruit, cut-up tomato and papaya, and occasionally grapes; practically nothing else. They all remain in perfect health as well as in excellent plumage and colour; all the red tones are perfectly preserved by the carotenes contained in tomatoes and carrots. Because of lack of time, I never could visit all the different collections in the Rio area, nor pay a visit to Dr. Ruschi at Santa Teresa, in the State of Espfrito Santo. But I saw those of Mr. Mario Ventura and Dr. Augusto Nim Ferreira, in Rio, as well as the aviaries of Mr. Nelson Kawall, Mr. Jorge Arnhold, and of the Zoological Park in Sao Paulo, all of great interest. Mr. Ventura and Dr. Ferreira live in town and have very little outdoor space. They, however, keep remarkably large and fine collections of birds, both native and exotic, either in rather small aviaries or in cages. Mr. Ventura has a number of outdoor flights, not very big, but cleverly designed to save space, in which are housed many Hummingbirds, Manakins, Tanagers, Sugarbirds and other small softbills, all in perfect condition. He also keeps, isolated in cages in his house, a number of hard-bills, mostly hybrids and colour mutations of Seedeaters ( Sporophila ) and Rice-Grosbeaks ( Oryzoborus ), many of them marvellous songsters. G 74 J. DELACOUR — BRAZILIAN BIRD COLLECTIONS It appears that there is in nature a large proportion of unmated female Oryzoborus because so many males are captured and kept as singing cage birds. The result is the occurrence of hybrids between them and males of various Sporophila. These natural hybrids are eagerly sought for. Dr. Ferreira has even less outdoor room than Mr. Ventura and most of his birds are kept in cages. His collection is large and varied, including, besides small birds, Woodpeckers and Parrots. They also are beautifully kept and in admirable condition. Mr. N. Kawall, in Sao Paulo, possesses an extensive garden, where he has built a long double row of aviaries. He also disposes of many cages in a hall. He specializes in plumage aberrations of native birds, which he propagates. He owns variants of many species. I particularly noticed a beautiful Troupial, whose normally black parts are of a light vinaceous brown, Blue Tanagers with white underparts and a series of freak Saffron Finches, some pure lutinos. Mr. J. Arnhold, also in Sao Paulo, has quite a different collection. He keeps and rears on a large scale, both in extensive outdoor aviaries which fill up a large walled garden, and in breeding box cages inside galleries, very complete collections of Finches and Parakeets, mostly Australian. It is all done according to the most modern techniques and very well kept. My visit to the Sao Paulo Zoological Park was a very pleasant surprise — I had not been in that city for 14 years, and at that time, there was no zoo of any importance. I knew that a new one had been built since, but I had no idea that it was either so large or so good. True to say, it has not been entirely finished and certain accommodations, mostly for the larger animals, have not yet been built permanently. But all that have been completed are particularly excellent and attractive; and it happens that many of them are dedicated to birds. This new zoo is situated outside of the huge city, among parks and wooded hills, and extends over a considerable area. There is a large and beautiful lake, with perhaps a hundred swans (Mute, Black and Black-necked) and many other birds. There are so many Swans that pairs do not try to establish a sizeable territory, nor to fight badly. But broods with their parents are removed as soon as they hatch into breeding pens, where they are reared. It seems to work perfectly. I also noticed big broods of Orinoco Geese, and other waterfowl. There are two big buildings, with partly open roofs. Groups of Cracids occupy one, water birds the other. Several species of Curassows and Guans are there, including a pair of the very rare Penelope ochrogaster. It is all roomy, well designed and decorated. Several very large flights, some still under construction, are situated in a wooded ravine, scattered along a winding path and surrounded by beautiful tropical plants and shrubbery. The aviaries themselves are artistically planted and adorned with rocks and logs. Many gamebirds, E. CALLEGARI — BREEDING IN CAPTIVITY BY ONE-YEAR-OLD SNOWY OWL 75 including four forms of Whistling Guans, Tinamous and other big birds live and breed in them, and it all looks very pretty. There are other houses and aviaries for smaller birds, of which a very good collection has been assembled, but I particularly want to mention the Hummingbird exhibit. It consists of a very large, walk-in aviary 100 ft. x 50 ft. x 30 ft., very well and lightly built of steel. As you enter it, you walk across a beautifully laid out garden, with rocks, streams, trees and tender plants. Some 400 Hummingbirds live in it and can be seen here and there as you progress. The flight is so roomy that they can escape each other’s attacks. It is a wonderful sight. All these accommodations are a great credit to Dr. and Mrs. M. P. Autuori, the Director and his wife. Mrs. Autuori has the paiticular charge of the birds and is responsible for the excellent design of the aviaries. They both should be highly congratulated, and also praised for the excellent laboratories which have been organized for research of various sorts. The Sao Paulo Zoological Park certainly counts as one of the progressive institutions in the world, unique in South America. # * # BREEDING IN CAPTIVITY BY A ONE-YEAR-OLD SNOWY OWL By E. Callegari (Ravenna, Italy) Having heard that Snowy Owls do not reproduce until they reach the age of three, it seems to me right to notify what happened to a pair of such birds I had bought at the Zoo of Basilea. Towards the end of the summer 1967, I obtained a pair of Snowy Owls born in the spring of the same year. They were so healthy and strong that in the spring of 1968, they laid seven eggs. One of them got broken, five were sterile, and one gave birth to a chick which, once grown, proved to be a female. This year, 1969, when they reached the age of two, they laid six eggs, all fertile. One chick could not be found any more a few days after hatching. Probably its brothers ate it. The other five Snowy Owls have grown normally. 76 NEWS AND VIEWS NEWS AND VIEWS Professor Alessandro Ghigi, Senior Member, elected 1911, celebrated his 95th birthday on 9th February, 1970. Claude M.

He writes: “ In 1964 I NEWS AND VIEWS 77 picked up some eggs on this farm at South Creake because the nest was amongst sugar beet which was being hand-hoed. These eggs were already partly incubated and I had them in an incubator for about 14 days before two hatched. One lived until the winter of 1965. I have not got any proper wintering quarters and these appear essential. My interest is really restricted to water fowl, and I have about 80 varieties, kept in approximately five acres of pens. The Stone Curlews proved a very interesting and worthwhile diversion.” # # # Last year I gave prominence to the fact that Dr. Alan Lendon had bred a Slender-billed Cockatoo, in the belief that possibly it had not been bred previously. In this I was, of course, very wrong. I am painfully sur¬ prised at this lapse. I am also surprised that only one member, Thomas Brosset, Gothenburg, pointed out that not only had there been a breeding account by Kenton C. Lint, with a photograph of a young one reared in the San Diego Zoo, in 1959 (1959, 107), but that I had referred to this and another success in my notes (1967, 21).

They fed the young well but I did not hear any more calling until the 28th. On 8th and 9th October a young one was sitting in the nest hole and it fledged next day. It is now at the Rode Tropical Bird Gardens. The adults have now moulted and are full¬ winged. They appear to be very hardy but still sleep in the nest-box.” # # # In the Los Angeles Times , 10th November, 1969, an article on attempts to save the Whooping Crane by breeding it in captivity at the Patuxent Wildlife Research Center stated that the Center’s Assistant Director for Endangered Wildlife Research, Dr. Ray Erickson, was insulted that the Audubon Society should have referred to him as an aviculturalist (sic). He is quoted as saying: “ I am not an aviculturalist. An aviculturalist is a zoo keeper. I’m a scientist, a biologist.” This is a little narrow in view of Colin Harrison’s definition of aviculture which was published in the Magazine (1967, 178). We feel that Dr. Erickson should remember that it was the efforts of men in many walks of life who were not zoo keepers, but were proud to call themselves “ aviculturists ”, that created both the background of knowledge and the climate of favourable opinion that made his present conservation work possible. 78 NEWS AND VIEWS A. C. Furner, before leaving for a visit to Uganda and Kenya, wrote: “ It may be of interest to report the unusual doings of two Senegal Parrots in my possession. Forty years ago I bought the first which has lived in and out of its parrot-cage in my greenhouse bird-room ever since. The second I purchased 25 years ago and it has had similar treatment to the first. Both birds were loose together in the greenhouse until a few weeks ago. They started flying on to my Gouldians’ cages and generally causing uproar. My wife and I placed the two cages, open door to open door, put a hollow log for them to play with, and so confined them to cage life for the time being. They now have four eggs and the later one, which turned out to be a hen, is sitting tight and is thoroughly enthusiastic about the whole job. Naturally the eggs are unlikely to be fertile, but it does strike me as being a good effort on the part of both birds — with ages 40 and 25 years respectively, and fully adult when they came into my possession.” # * * It is pleasing to learn that John Wilson has a Pesquet’s Parrot Psittrichas fulgidus. Since Lesson described and named this parrot Psittacus pecquetii in 1831, there have been only about a dozen living specimens in this country. It has often been said that the first known living bird was in the Earl of Derby’s collection at Knowsley Hall. This assertion is probably based on Lear’s colour plate in the parrot volume of Jardine’s Naturalist's Library (1836). Like many present-day artists, Lear preferred to paint from living birds, and so it is presumably assumed that the bird depicted was living. But it is more likely that the model was, in fact, a specimen in Lord Derby’s museum. There can really be little doubt that the first live Pesquet’s Parrot, a female, was owned by the Marquess of Tavistock in 1918. After being in his possession for a couple of years it passed to Mrs. M. Dalton-Burgess. It died in 1924, in which year Mrs. Dalton-Burgess acquired a pair. Wilfrid Frost imported one in August 1921; after a short stay at the London Zoo it continued its journey to America. In October, 1926, Walter Goodfellow brought two for J. Spedan Lewis — one of which he presented to the London Zoo. Then in August, 1927, Walter Goodfellow brought a pair for Herbert Whitley. One died before Christmas: the other was his National Show winner that died in February, 1928. And there was a female living in the London Zoo in 1936. I believe I saw all of these, with the exception of Lord Tavistock’s original bird. The majority seem to have been rather short-lived. It is to be hoped that John Wilson’s bird will fare better. Incidentally, who was the Pesquet later to have this parrot named in his honour? In old specific names authors have variously named him Pecquet, Pesquet, Pequet, Pequett, Pescquet and Pescquiet. # # # A. A. P. REVIEWS 79 REVIEWS BIRDS OF PARADISE AND BOWER BIRDS. By E. Thomas Gilliard. London: Weidenfeld & Nicolson, 1969. Price 6 gns. Unfortunately very few aviculturists have the opportunity of obtaining live specimens of these gorgeous birds ; the appropriately named Birds of Paradise, unsurpassed in their beauty and bizarre ceremonial dances, and the Bower Birds with their extraordinary display grounds, one of the strangest and least understood phenomenon in nature. These birds are now very strictly protected in their native New Guinea and a few adjoining islands, yet the annual killing of more than 80,000 males — mostly of only three species — did not threaten any of the birds of paradise and the author advocates that small numbers of the live birds might be collected each year and exported to zoos and similar institutions, to be used for educational purposes. The author, accompanied by his wife, an ardent naturalist, made five expeditions to some of the wildest parts of New Guinea and brought back a wealth of information regarding the habits of these little known birds. He advances the theory that the paradise and bower bird groups are derived from a single colonization of New Guinea, first arboreal monogamous birds which subsequently became polygymous and then diverged into birds of paradise and bower birds and reverted to monogamy. The evolution of bower building is so remarkable that one naturalist has suggested that birds should be split into two categories, bower birds and all other birds. The males of some species build elaborate walled bowers of sticks and decorate them with bright objects and even with paint. Others construct towers up to nine feet high, some with tepee-like roofs and internal chambers situated on circular lawns that they tend carefully and embellish with golden resins, garishly coloured berries, irridescent insect skeletons and fresh flowers replaced as they wither. These bowers are stages on which the males perform intricate routines of sexual display and mate with the females of their species. There are only 18 species called bowerbirds, all confined to New Guinea and adjoining territory but there are in all some 85 species described as arena birds with a worldwide distribution. The bower birds are con¬ sidered to be at the pinnacle of area evolution and have gone a step beyond the most richly ornamented arena birds, substituting fancy houses and jewellery for colourful plumage. The birds of paradise on the other hand have developed most spectacular varieties of plumage, both in colour and form, combined with characteristic display performances. These are described in detail, when known, together with the breeding behaviour and other observations on the various species, including their distribution. Most of the species are illustrated by photographs or sketches the majority by the author. There 8o REVIEWS is also a useful list of ornithological explorations in the New Guinea and Moluccan Regions and a bibliography. There are three appendices, one giving a list of ornithological explora¬ tions in the New Guinea and Moluccan Regions and another the account of a visit to Little Tobago in 1958 where Sir William Ingram, founder of the Illustrated London News , succeeded in placing 44 Greater Birds of Paradise in 1909. It was estimated that by 1958 there were probably less than 35 birds of paradise on the island but some were third generation birds. Recently (1964) a hurricane is reported to have driven some of these birds of paradise on to Tobago Island. It is sad to have to record that the author died of a heart attack in New York in 1965 while the manuscript of this volume was in the editor’s hands. E. H. * * # AUSTRALIAN PARROTS. By Joseph M. Forshaw. Melbourne: Lansdowne Press (distributed in the U.K. by Witherby: London) 1969. Price £13 10s. With the enormous interest in the Australian parrot species and with the lack of an adequate recent work covering the whole group, this present book comes as a welcome and much-needed work consolidating the increasing but scattered information on the subject. Solid would seem to be an appropriate term since it measures 12 x 10x2 in. and registers 6j lb. on the kitchen scales. The book covers all the Australian parrot species, including the Red-fronted Parrot and Kaka by virtue of their occurrence, now or in the past, on Norfolk Island. Mr. Forshaw has adopted a classification which recognizes three parrot familes in Australia. This seems to be an upgrading of taxonomic subdivisions, of a type to which specialists are particularly prone since they are more conscious of the diversity of the group which they are studying, and may not recognize its relative unity when compared with other groups. There are some interesting regroupings. The Cockatiel is recognized as a cockatoo, the Galah (Roseate Cockatoo to non- Australians) separated in the monotypic genus Eolophus , and Bourke’s Parrot (they are called Parrots in this book, which might help us to do away with that unfortunate term “ parrot-like ”) is regarded as a dry-country Neophema species that has lost its green colour, and it is placed in that genus. The introduction discusses the habitat and has six pages of habitat photographs. It also discusses distribution in general, but Spencer’s classic concept of three zoogeographical sub-regions, shown on a map, is probably obsolete since Keast has shown the situation to be much more complex. There is also an introduction to the text layout, and a short introductory section on keeping parrots in aviaries. REVIEWS 8l The main bulk of the text is devoted to individual species. These are arranged in a systematic sequence. Each family, subfamily and genus is introduced by a brief indication of their special features. Each species has about three pages of text devoted to it, accompanied by a small map of distribution and one, or in some cases two, full-page colour plates. These plates are mostly close-up photographs of single birds, or more rarely of pairs. These are fine detailed studio-type portraits, but I must admit that I appreciated the occasional photograph from the natural habitat, especially one of a Galah drinking, and I felt that some of the size might have been sacrificed to include a picture of the plumage of the young, or in some cases of the female which was not always included. A few of the plates show evidence of poor colour values. Apart from the transposed pictures of the two lorikeets, mentioned by the publishers, there is another eiror in that the picture of the Twenty-eight Parrot is not in fact that of the race semitorquatus , but a bird in mixed plumage, probably from one of the areas in South-west Australia where the two forms are interbreeding. The five paintings of J. C. Yrizarry illustrate those species for which photographs are not available. The great value of the text lies in the incorporation of up-to-date information. A description of the adults of both species is given, but the immatures are dismissed rather summarily. The distribution is summarized in the text in addition to being shown on a map. The various subspecies, where these exist, are described, and the ranges given. The type of country occupied in various parts of the species range is summarized under habitats, and a paragraph is devoted to its status, in terms of abundance, within its range. The section on habits contains information on the general behaviour, and in the more adequately studied species summarizes the normal daily routine. In a few instances it indicates the paucity of the data available. A section on movements is particularly necessary on a continent where variable drought conditions may cause many species to show seasonal or periodic movements within their range, and allowance must be made for such movements when evaluating a map of the overall distribution of a species. The description of flight characters and voice are given, although these are probably of greater value to the field observer than to the aviculturist. The sections on feeding give information, mostly qualitative, on the food taken; identifying many of the foodplants and indicating the variety of the diet; combining both field observations and the examination of stomach contents. In discussing breeding the displays are briefly described and data on the nest, eggs, and behaviour during the breeding period, and development of the young is given for each species. There is a final short section on the keeping and breeding of the species under aviary conditions, and the known hybrids are listed. There is a useful bibliography at the end of the book, but there is no indication of the fact that it is limited to the publications referred to in H 82 REVIEWS the text. It might have been made more useful to the user if it had included a fuller list of at least the major publications on the Australian parrots. The inclusion of a gazetteer is another helpful feature. This is a very useful work and one that most aviculturists will want to possess. In the circumstances the very high price is unfortunate. The reviewer was interested to see a recent review in an Australian ornitholo¬ gical journal of Immelmann’s book on Australian parakeets. This costs £2 and the reviewer commented that at this price only the most enthusiastic parrot-lover would want to buy it. One wonders what he would have said about the present work! Another cause for complaint is that the large colour plates are stuck in individually on the back of pages of text, being stuck along the top edge only. Users will find that as the book is opened and closed the lower inner corners of the plates become bent in and will have to be glued down if the book is not to acquire a dog-eared appearance. Also the book is far thicker at the middle than at the edges and is therefore difficult to handle, and if used frequently the binding at the spine begins to show signs of strain. The layout of the text is lavish, with plenty of spaces, and the section headings and maps considerably reduce the amount of text on a page. One wonders whether with some economies, and with something less of a coffee-table book as the ideal, the publishers might not have produced a more reasonably-priced work which would have reached more readers; and the last point is the crucial one, for in the long run the value of a book must be judged to a large extent by its availability to a large number of readers. In spite of such criticisms it is still a work to be recommended, not only to aviculturists but also to ornithologists in general and to the non-specialist bird-lover. C.J. O.H. # # # FREMDLANDISCHE STUBENVOGEL (Foreign Cage and Aviary Birds). By H. Dost. Published by Verlag Eugen Ulmer of Stuttgart, Germany, 1969. Price D.M.980. This excellent little book is one of series on animals (Ulmers Tier- buchreihe). It deals with a very large number of birds, including representatives from different families, that are commonly, or not-so- commonly, kept in captivity. Many species of starlings, babblers, finches, buntings, cardinals, flycatchers, thrushes, weavers, whydahs, tanagers, etc., are dealt with and 72 of them are illustrated in colour. The illustrations are adequate rather than superlative in quality but it is nice to have so many of them. Some of the species chosen, such as the Corsican Nuthatch Sitta whiteheadi , are hardly likely to flood the bird markets in the foreseeable future (at least, I hope not). They have, presumably, been chosen because there was much useful information available on their behaviour and needs in captivity and this seems to me a justifiable reason for including them. REVIEWS 83 Each species is dealt with concisely but in some detail. General information likely to be of use to the aviculturist is followed by dis¬ tribution; description, with age and sex differences ; voice; care needed in captivity ; food ; and breeding. A really good feature is that full references are given (cited in text and details at back of book) to accounts of successful breeding, studies on the species in captivity and so on. I assume that the waxbills and other estrildines are likely to be dealt with in a separate volume in this series. Otherwise their complete omission, except where some of them are named as hosts of the parasitic Whydahs, would be unaccountable. A minor defect of the book is that the index is not in alphabetical order, the birds being listed in the same order as in the book, which rather negates its purpose. All the same this is an interesting and useful book that can be recommended to all who read German. D. G. # # * PAPAGEIEN IN HAUS UND GARTEN (Parrots in house and garden). By W. de Grahl. 1969. Price D.M. 19-80. This is another volume in the same series as the book reviewed above. In my opinion it is a better one, perhaps I should say an even better one. It differs by including much information about the ecology and habits of parrots in a wild state. I hasten to add that I use the word “ parrots ”, as does the author, to include all psittacines — lories, lorikeets, lovebirds, typical parrots, parrakeets, cockatoos, the lot! (It is to be hoped, incidently, that parrot-keepers will sooner or later come to their senses and use the word “ parrot ” as one uses “ finch “ pigeon ”, “ bunting ” and so on, and drop the misleading and cumbrous “ parrot-like ” at present in vogue.) To get back to my job of reviewing this useful and attractive little book. Like its companion volume it contains concise but quite comprehensive information about each species and how to keep and breed it, where such information is known. Unlike the first book, however, it does have an easy alphabetical index to both common and scientific names. It is illustrated with many photographs of living birds, ten of them in colour. There is a colour plate showing the identifying head and forepart colour patterns of 18 species of Amazon parrots. The publisher’s blurb on the back cover is painfully “ twee ” but it is most emphatically not a sample of what is between the covers, which can be heartily recom¬ mended to all who read German and are interested in parrots (psittacines). D. G. 84 CORRESPONDENCE CORRESPONDENCE MEAT AND PROTEIN FOOD FOR PARROTS In view of some of the points raised in Mr. Smith’s letter below, we have asked one or two other aviculturists for their experiences and will be glad to hear from others regarding the use of meat and insects as food for parrots. My own experi¬ ence with a Little Corella was that it liked roots and root vegetables best ; and if not carefully watched would climb up at meal times and gaily throw the meat off a plate to get at the vegetables; but once its vegetable wants were satisfied it would spend a little time delicately picking scraps of cooked meat from bones. The recently published book on Australian Parrots by J. M. Forshaw gives some references which relate to some of the points raised. The eating of wood-boring grubs by Black Cockatoos is described, and reference is made to masses of pollen in the stomach of a Purple-crowned Lorikeet, and to the eating of entire flowers by Barrabands’ Parakeet (which Forshaw calls the Superb Parrot), and by the Red-capped Parrot. 14 Dawlish Avenue, C. J. O. Harrison. Perivale, Middlesex. I often get for postmortem various parrots that sometimes between their demise and my receipt have obviously been eaten by something or other. Even budgeri¬ gars, from well-inhabited flights, almost always have the exposed limbs “ chewed down to the bone ” and possibly the head and some of the chest nibbled. I keep Cyanoramphine parrakeets, and to me they are the most tractable of any psittacine species. They may bicker; but a threat is as good as a fight and it is seldom if ever that even a feather is lost when a hint to move away from a claimed nest-box isn’t taken. The humorous quote originating from Canon Dutton, concerning three New Zealand hen parrakeets who, to avoid spoiling a good friendship through jealousy, combined together and killed and ate the single cock provided, has always had me puzzled. Birds do differ such that no one can generalize about any species; but a Cyanoramphus male’s beak would have been twice as large as a female’s and, like birds of prey, this parrot genus has the hens one-third as small again as their spouses. One often hears of murder and cannibalism in other sorts of parrots, and I have always thought that Canon Dutton’s New Zealand hens were grossly maligned. New Zealand parakeets or, to be more specific, those two that inhabit the near- Antarctic Antipodes and used to inhabit Macquarie Island are always stated to eat a considerable quantity of dead penguin and seal-flesh. Keas, some at least, seem to have taken to eating mutton live as well as dead. In captivity most parrots and parrakeets will eat mealworms or maggots. The Keston Bird Farm used to give boiled cod to their larger breeding parrots, and Black Cockatoos of the Calyptorhynchus genus are reputed to eat the larvae of wood-boring beetles, while doubtless there are other carnivorous tendencies in Psittacines. What I have found most interesting in these early Avicultural Society magazines are the references to meat-eating in this family of birds. In volume 2 of the first series, in a letter, Mr. C. P. Arthur notes that Pennants, Crimson-wings, Kings, Rosellas and Mealies all avidly took chopped fresh meat intended for a Jay that shared their aviary. Most interestedly he then goes on to say that Grand Eclectus Parrots are very fond of mice. Each of his specimens consuming two a day, when he could procure them ! In volume 8, again of the first series, Mr. T. B. Whytehead writes to tell of a cockatiel, that least malevolent of parrots, which ate the head off a mouse that it had, presumably, caught in its cage. The diets of wild parrots are not well understood. I know that crop analysis has been undertaken ; but seeds are shelled and other, softer, matter is well masti¬ cated. Do Lories for example eat the insects that must be as attracted to the honey-bearing trees as the birds are? Nectar is not a sufficient complete diet — it is, after all only a solution of sucrose, glucose and/or fructose. Or do Lories digest the pollen as well — like bees (Bees feed the larvae on pollen, honey is only used to supply energy to the adult bees)? And what do Lorikeets eat when the trees aren’t blooming? I have seen Platycercines, in an aviary, chewing away on an earthworm like a child with a “ liquorice bootlace ” ; is this normal or abnormal behaviour? Sidney Porter writing somewhere in the magazine said that with a large collection of diverse, extremely rare, Amazons when these were fed on a CORRESPONDENCE 85 “ natural diet ” of fruit, vegetable and seed they started dying one by one. Yet when put, partly out of boredom with the birds, into small cages and fed on seed they stopped dying off. My own assumption would be that perhaps by then he had “ naturally selected 55 and that what he had really shown was “ survival of the fittest ”. In these early magazines, and for some later, should a bird die or start feather-plucking, the food is immediately blamed be it sunflower, safflower or hemp. And this blame becomes a correct diagnosis and woe betide anyone who feeds birds differently from the author of the article. I wish that I had such self-assurance in any of my diagnoses as to aetiology. 158 Broadway, G. A. Smith. Peterborough. There have been many discussions concerning the allegedly harmful effects of feeding meat to parrots. Over the past ten years or so I have given my African Grey Parrots a meaty bone for their supper, with no harmful effects, but on the contrary they have yearly produced fine healthy youngsters. I obtain from myj butcher lamb neck-bones, that have been boned from the upper shoulder. There is not a lot of meat on them but the birds pick them clean. I obtain these from my butcher once a week, when the boning is done, and chop them into small pieces which the birds can handle comfortably. These are cooked slowly for two hours in the oven in order to extract all the fat. I am quite convinced that any harm that birds suffer from meat eating is because of the fat in the meat. I keep the cooked bones in the refrigerator and each day those that are used are warmed in the oven, since the birds much prefer a warm bone to a cold one. When there are babies in the nest, and they smell the appetizing warm bones, there is great excitement, the babies demanding to have their share quickly. If only one pet bird is to be fed, it can be given a lamb chop or cutlet bone left from the table, but again, no fat! I have seen people give parrots fatty bacon rinds and other fatty meats, and I am quite convinced that it is for this reason they sometimes experience trouble. A pet bird may also be given a chicken bone and will crack the drumstick and relish the marrow. No pork bones should be given as these are too rich and fatty. Finally, I cannot stress too often, no fat! Silver Springs, E. Wicks (Mrs.) Beaufort Road, St. Leonards-on-Sea, Sussex. I understand that Mr. G. Smith has written enquiring about meat and proteins in the diet of parrots, and perhaps the following notes based on my experiences may be of interest to him. With regard to Lories and Lorikeets I feel that there is no doubt at all that live food is taken in considerable quantities, and in captivity mealworms are always sucked dry, and never eaten whole. I do not think live food is essential to these birds, but it certainly seems beneficial, and having found a satisfactory regimen of feeding I am unwilling to change. These are the only birds I keep on a strict diet consisting of Hastings Nectar diluted with the juice from stewed dates and sultanas, mealworms, and a few grains of soaked sunflower. I have had a pair of Yellow-backed Lories that have kept in perfect condition for 11 years. This length of time is not unusual for these birds which often seem to live to a great age, but I put them on this diet when I found that they suffered from fits when kept on a more mixed fare. Friends who have given these birds a wider variety of food seemed to lose their birds, so there was not much point in trying further. I think that live food is most essential. With regard to the ordinary parrots, Amazons, etc., there seems such a wide variety of foods that must be eaten in the wild, and live food of a sort is probably eaten. The one thing that is certain about wild parrots is that their natural diet can bear little relationship to the food we give them in captivity. Some parrots will take mealworms, and others are not interested at all. I always give my birds nectar and soft food as well as seed, and many, particularly the Blue-headed, prefer soft food every time. The Australian Parakeets including the Budgerigar are definite live feeders when given the chance, particularly when rearing, and they will eat a lot of mealworms then. Budgerigars certainly need to see other birds feeding on them to encourage 86 CORRESPONDENCE them to start, but once they acquire the habit they feed freely on live food. This habit of the Australian Parakeets taking live food was, I think, confirmed on the recent collecting expeditions undertaken by the Natural History Museum, South Kensington. The habit of the Kea Parrot of New Zealand in reputedly killing sheep for their kidney fat is frequently quoted, and perhaps I may be pardoned for the following notes, which, while not strictly speaking of avicultural interest, may warrant some thought. As a preamble may I mention that for over 40 years I have been connected with the Australian and New Zealand wool trade, and in the course of this time I have met many sheep farmers. Speaking generally this group of people once they get beyond birds that are harmful to sheep or other forms of agriculture, take little interest in birds. A few years ago I was connected with a group of farmers who ran sheep in the high country where Keas are found, and I never met one who had himself lost sheep through these birds, or had actually seen a Kea attack one. All knew the story and it was always “ Old Jim ” or “ Old Harry ” who had supposedly lost sheep by this means. Eye-witnesses were, to me, non-existant. This does not necessarily prove that the stories are unfounded, but I think that they may well prove to be widely exaggerated. It may be of interest if I give the results of my enquiries. Until the introduction of pigs by Captain Cook in New Zealand, there were no mammals there apart I believe from a few mice, and the Maoris who did not settle in Kea country in any numbers. Prior to the arrival of the Maoris there were a race of people there called Moa Hunters, but nobody seems to know anything much about them. At any rate it seems more or less certain that there were no mammals in New Zealand until comparatively recent times. The native bush was therefore almost exclusively spread by means of birds, wind and insects. It was the solid pathless masses of bush that made the first settlers fear it so, and burn it off wherever possible. The Kea country was probably first put under sheep about 120 years ago. Keas are highly intelligent birds, physically very tough, and equipped with a powerful beak. They also have a great sense of fun. One friend of mine used to go and visit a relative who was working on the marvellous fiord road near Milford Sound. The men were housed in wooden huts with corrugated iron roofs and snow fell frequently. At dawn the camp was awakened by the Keas who flew down to the ridge of the roof, and then slid down the slope for all the world like otters or children. The late Sydney Porter, who had a pair of these birds in an aviary with a running stream spanned by a bridge found that the Keas dropped a tin in upstream, and then ran across the bridge to see it come out the other side. That Keas are highly mischievous is also true. If the hotels now opening in that area leave the windows open and unguarded, Keas will get in and rip the place to pieces. The above notes on the Keas’ mental make-up are important. I have always thought that parrots, dogs and small children have a lot in common in what they find of interest. That much of this is concerned with minor destruction is also a fact. I do not know if we will ever see a parrot “ Demo ” — probably the activities of University Students are a little beyond them ! I understand that the high country where Keas are found was first stocked with Merino sheep from Australia, and the snow experience of these sheep would be slight or non-existent. This is another point that gives a clue to the whole puzzling business. The most likely explanation I heard was from a farmer who in the slump of the 1930s was forced to work as a shepherd in very high rough country — too rough to muster the sheep on horseback. All the work had to be done on foot. Incidentally he earned 30 shillings a week for this gruelling work, which does not seem much by present-day standards for this lonely and hazardous work. Many sheep became bogged down in snow drifts, and unless the shepherd or his dogs found them, which was not very likely, they died. This farmer suggested, and he had no great natural history knowledge, that it was probably the struggling and bleating of these sheep that brought the Keas down. Anyone who has kept mixed collections of birds has seen how something unusual, a frog or a mouse will bring all the birds down to look at it and the same thing applies if a bird catches itself up anywhere in an aviary. Parrots particularly are very prone to attack anything in difficulties. CORRESPONDENCE 87 We therefore come to a situation where an alert active bird sees something of which it has no race experience at all, struggling and crying in a snowdrift. What is more natural than that the Keas should come down, and, if they found that the strange object was harmless, should give it a hefty bite? The long powerful beak of a Kea would rip a sheepskin easily enough. I do not know if the bit about the kidney fat is factual, or is just a trimming. There is another theory that the birds were first brought down to the drying frames where the skins of slaughtered sheep were hung before shipment, but if this was the case I should think that it must have been flies that they were after. The country lived in by the Keas is heavily stocked with deer, but I have never heard of an attack on these animals. I suggest that deer being more accustomed to snow do not often get bogged in snowdrifts. I managed to get a friend of mine interested in the problem, and he arranged a trip to try to get some facts. As he knew most of the station owners personally it would have been a good test but unfortunately he died before he could undertake the journey. Surely we have members in New Zealand who could track down this fascinating story, and there must have been some research done on what has become one of the main legends of ornithology. I may be wrong but I have a feeling that this is a classic case of where an incident has been built up into a legend. I may be wrong and the Keas may live on sheeps’ kidney fat, but if I know anything of New Zealand sheep farmers, if there had been very much truth in the story the Kea would have followed so many other New Zealand birds into extinction before the turn of the century. This story apparently started about the 1860-70S and it is as well to look at the background of the whole thing. The South Island of New Zealand, or at any rate the southern part of it, was colonized by Scots, men who in their native land had had to cope with the attacks of eagles and foxes on their flocks. New Zealand possessed neither of these, so any further predation was unduly obvious. It is hard these days to realize the absolute isolation of these mountain sheep stations in the early days. They are hard enough to travel in now but before the country was widely settled the loneliness must have been frightening. The absence of any wild animal or other human for many miles must have led to much family talk over firesides and ideas must have become a matter of folklore, much as it was in the Scottish Highlands. The general opinion nowadays of the Victorian woman is of a frail fainting creature. This may have been the case with those in England, but anyone who thinks that the women who opened up the country in Australia and New Zealand, South Africa or South America were of that type would be well advised to think again. One of the greatest hardships was lack of news or indeed anything to think of but their daily hard round. The men always had things to do away from the Station, but the women were literally tied down. Any story, true or false was passed on, and in the absence of any firm news such stories as that of the Kea were passed into folklore. If anybody can add to the foregoing, I shall be pleased to hear. While on the subject of New Zealand birds, I would mention that a colleague of mine made a detailed tour of New Zealand Sheep Stations recently, and in the course of this journey stayed at a Station in the South-East of the North Island named Huiarau. This is an old established station, and is named after the Huia bird. The name is pronounced hoo-yah. The Huia is, I believe, extinct or nearly so, but its main claim to fame is that the birds possessed long ivory coloured beaks, that of the cock being shorter and heavier for chopping open old logs, and the hen having a longer probing bill. The bird is about 19 in. long. The bird was apparently shot out as no Maori considered himself well dressed without a Huia beak hanging on his watch chain. There is a rather curious parallel here with the Ivory Billed Woodpecker of Florida which was driven to near extinction for the same reason. Man has wiped out numerous species of animals and birds for one reason or another, but these are the only two cases I know of where birds were driven to extinction by male adornment.

Reid-Henry (Woodford Green, Essex, England) There are two species of tiny kingfishers in Southern Africa which can be confused in a casual examination. They are the Malachite kingfisher, Corythornis cristata (Pallas) and the Pygmy kingfisher, Ispidina picta (Boddaert). It is with this latter that we are now concerned, and particularly with the race natalensis. Briefly the main difference is in a matter of habitat. The Malachite kingfisher is a bird of the rivers and the environs of open stretches of water, whilst the Pygmy kingfisher is predominantly a dry- country bird feeding mostly on grasshoppers, tiny lizards, caterpillars, beetles and the like, often very far from any water. Its nest is in the typical hole in some earthy bank, and is in every respect similar to that of almost any other member of the family, but the site chosen is more often the side of a termite mound into which the bird excavates the tunnel, rather than the softer, sandier site of a river bank. The extra work involved in digging a hole through a hard sun-baked surface finds its effect in the greater wearing down of the bill, for it is very noticeable how short the beak of this bird is compared to that of a Malachite kingfisher In captivity when the bird is relieved of all this hard work, the beak quickly becomes overgrown and out of character, despite the lesser work involved in smacking its bill against a perch in order to stun its food, which kingfishers always do! There is not much of a white patch on the lower cheek where the Malachite carries a considerable flash, and the back of the neck is chestnut where the Malachite is blue-violet. However, there is only an iridiscent small blue patch below the ear-coverts, whereas the whole of the side of the Malachite’s head above the eye is blue-mauve or violet. It is on the crown that the main obvious difference is to be seen; for the Malachite kingfisher erects an extraordinary barred and tipped black shaped tiara of long emerald green crest-feathers, in moments of excite¬ ment. The Pygmy kingfisher wears no such adornment but instead its crown centre from bill to nape is rich ultramarine blue barred with black. They are both most beautiful little birds. The Pygmy kingfisher is much addicted to migrating at night and frequently is attracted towards lighted windows, where it often either enters houses, if the windows are open, or breaks its neck against the glass. I 9° D. M. REID-HENRY — THE NATAL PYGMY KINGFISHER In one case I was told about the bird that flew into an African’s house and was promptly skinned and eaten as part of the man’s supper! In another case the bird was taken alive and unharmed to school by a small boy who wanted to give it to his nature-study teacher. This lady brought it along to me in a shoe-box and I agreed to have some decent accommodation made and look after it. I would like to describe the cage I had made for this bird in some detail because it has served me well for several purposes. It was made strongly so as to serve as a packing case as well as for other purposes. The top, when it is used as a cage is a fine mosquito mesh of copper wire, whilst the front is a sliding sheet of plate-glass, going into position from the top. The door is the side which opens as two wings and which can be screwed in solidly, or left as a door as required. The rest of the construction is of oil-bound hardboard on a stout wooden frame. It serves equally well as a cage for birds or insects, whilst the overall size is enough to give a lot of room. The floor I covered with dead leaves and sand and I placed a water container and the daily ration of live insects, geckoes, etc., inside by simply lifting the glass front a few inches. Perches were natural branches which were laid on the floor so that the twigs could stand up in interesting positions to show off the bird. In this cage I kept the kingfisher for about six months until it was time to return to England, when I took him out into the bush and let him go. Feeding involved a daily stint with a butterfly net in the vlei to catch grasshoppers. Another stint with the net indoors after sundown brought me a ready harvest of moths and beetles. I found it astonishing to see how large an insect this tiny bird could swallow: large moths of the common sort would be divested of their wings and then swallowed without difficulty, but there was a danger from large and powerful grass¬ hoppers whose enormous kicking power had to be curtailed for fear of the little bird’s losing an eye. Whilst this bird is as I have said a species of the dry country in the main, he was very keen to take several baths a day and was always ready to retrieve any food from under water, and I believe its dry-country habitat is a comparatively recent adaptation. There are other kingfishers in Africa and Asia which behave in exactly the same way. It is evident that as a family kingfishers are very adaptable to change in dietary habits, but they have little stamina to withstand cold or the effects of prolonged fasting. In general they are peaceable birds and may be kept in company with other species without danger. I look forward to a time when it will be possible for me to keep some of the other African species and compare my notes. Certainly I have found kingfishers always rewarding in every way and look back on this particular bird with great pleasure, counting myself D. M. REID -HENRY — THE NATAL PYGMY KINGFISHER 91 singularly fortunate in having had the opportunity to study such an interesting bird so closely for so long. He could stand up and look as thin as the proverbial rake, or he could sit down and look almost spherical in shape. I never saw him sit on one foot, and because of their shape and structure it would not seem possible to maintain the position for long. Their feet are short and set widely apart so that it would seem hard to balance the centre of gravity over one foot. I have kept several kingfishers as opportunity came, and I have never to my recollection ever observed them to sit other than on both feet, except to scratch their heads, or to stretch. Another reason why such a posture would be difficult lies with the structure of the toes. Like all members of the order Coraciiformes the proximal half of their outer toes are stuck together with the middle toes in a common sheath and so cannot be spread out to distribute weight. Hoopoes, by the way, do not have the same degree of restriction as most other members of the order. It is a matter of wonder to me that birds with such beautiful plumage as kingfishers can bring up their young in the squalid conditions of the nest-hole. All the kingfishers, hoopoes, bee-eaters, rollers and hornbills whose domestic arrangements I have studied are united in their indifference to filth of the most offensive kind. One would imagine, if in ignorance of the provision of nature against it, that tiny growing feathers would become ruined by ordure long before the time came for their owners to leave the nest, but the truth of the matter is that these birds retain the spiny sheath in which the feather is encased during growth until almost the time when they are fully grown. Thus they are wonderfully preserved from contamination, and the plumage breaks out of the sheath only when the young birds are nearly ready to leave. They emerge from the tunnel all with unspoiled feathers and thereafter sit around on perches near to the tunnel entrance whilst awaiting food from their very industrious parents. Unlike the passerine birds which bring at one visit enough food to supply morsels to each of their offspring, kingfishers usually can feed only one youngster at each visit. On the other hand, there is usually much more substance in one feed to a kingfisher than in one mouthful to a thrush. Nonetheless, the comings and goings of parents of these birds are very busy affairs and the industry prodigious, for the number of young in a brood is high. In the case of the Pygmy kingfisher the brood is, according to Roberts four to six, but in some other species the number is frequently eight or even more. As is so often the case there are casualties in the nest, and not all eggs laid actually hatch. Of those that do, some young get neglected and die, but the quantity of insects, particularly grasshoppers consumed by the survivors must be great. One is disturbed to learn that the use of DDT is on the increase in various parts of Africa in an attempt to clear areas of harmful insects, but the damage to beneficial birds may well be a far greater evil in the end. 92 L. A. SWAENEPOEL — INDIAN RINGNECKED PARRAKEETS INDIAN RINGNECKED PARRAKEETS ( Psittacula krameri manillensis) By Dr. L. A. Swaenepoel (Lembeek, Belgium) Indian Ringnecked Parrakeets, and indeed all the allied species, have always been great favourites of ours. Most of all, however, our hearts are sold to the beautiful mutations of Psittacula krameri manillensis. We used to be the very proud owners of a pair of blue Ringnecks, who gave us three lovely youngsters in 1967 and again in 1968. Last year, however, the hen went down very early — as she usually did — but only one egg of the clutch of four was fertile. This hatched on 10th April, when it was bitterly cold after a deceiving spell of sunny Spring weather. This youngster died at the age of 10 days. It did not thrive well during the last two or three days, and I had no opportunity to put it under another hen. On the other hand, I was loathe to bring the baby in into the trust¬ worthy hands of my wife, as I did not wish to wear her out so early in the year. As a matter of fact, she was put to very good use some months later, to try her hand at rearing Kings from the egg. As it was, the old blue Ringneck hen went down a second time. All four eggs of this most unusual second clutch were fertile, and expectations were high. On 8th June, the hen was found dead in the nest. The eggs, due to hatch on 10th June, were tried out under Cockatiels, but unhappily all were dead in shell. Post-mortem of the hen showed a huge haemorrhage in the lungs, in the abdominal cavity and in the crop. Apparently, the right atrium of the heart had burst. This hen died as the perfect symbol of the excellent mother : she had been covering the eggs even while her body grew cold and was discovered in the attitude of brooding. Bearing in mind that one pair of a certain species — or of a mutation thereof — is a very poor and hazardous way to success and to build up a breeding strain, we had paired up several other birds. Two acquired split blue cocks 1967 were paired up to two of our own bred hens of that same year. The blue hens seemed a certainty: anyone could easily tell the more slender bills, the differences in the size and shape of the heads, the more elegant feet and also a decidedly different hue of the iris. The behaviour, too (many times observed), pointed the same way: the hens always sat close to the cocks, and we were delighted to possess such well behaved and loving young pairs. Being of a rather impatient nature, I had, on several occasions, plucked some small feathers in the nape of each one of these four birds, so as to see if new feathering would show a trace of the black collar of the male. L. A. SWAENEPOEL — INDIAN RINGNECKED PARRAKEETS 93 The green split blue cocks showed some of this male colouring in the autumn of 1968, but the two blue hens, true to my expectations, grew back the blue female feathers, even when I plucked their napes in March 1969. I must confess, that I was gradually becoming prouder in my abilities for sexing immature Ringnecks. The two young pairs did not visit the provided nests, as we had hoped ; still, one must not be too severe with two-year-old Ringnecks. However, in the moult of 1969, the two blue hens grew themselves a lovely black collar; those two simulators have, since then, been two lovely, lively cocks. In the meantime, we had built up another pair of blue Ringnecks; unrelated 1968 birds of our own breeding. The supposed hen of this young pair eventually suffered from a very bad moult, for which I have found no explanation ; in fact, she went nearly bald in a few months time. No sign of plucking nor of new growing feathers, in spite of a varied diet and a supply of vitamins. I found her dead, nearly-naked body hanging on the wire netting on a cold August morning. Indeed, post-mortem showed that she was a hen. The remaining 1968 bird that had been living in the same aviary, looks like a cock though no ring is as yet visible. Still, I’d not take a bet on him! Our last pair of this mutation consists of a blue hen with a broken and partly overgrown lower mandible, probably due to an accident when she was quite young. Occasionally, we have to catch her in order to clip the broken part of this lower mandible. She can feed all right and is in good condition, but apparently she is unable to feed a baby: on two occasions, she had newly hatched youngsters that died with an empty crop. Her mate is a green cock split for blue and for lutino ; he was loaned to us by a friend. In 1966 and 1967 this pair were living at our friend’s establish¬ ment; both years they had fertile eggs which never hatched. On taking them over to our aviaries, we decided to foster her eggs out with a reliable pair of normal green Ringnecks, excellent parents, while the blue hen was able to brood the green’s eggs, with no results. In 1968 we reared from this pair two blue youngsers, the third egg being infertile. This made it easy to divide the clutch, sticking to the breeding- terms. In 1969 this pair had again three eggs, one of which was clear. Upon hatching under the normal green hen, on 26th April 1969 we noted a black-eyed and a red-eyed baby. Then the suspense started! Would the red-eyed baby turn out to be an albino? I wonder if any nest has ever been so closely surveyed. We had to wait about three weeks, wondering if the first pin-feathers were going to be white or yellow and, in the end, hardly believing that they were white, indeed! This albino baby, a hen of course, grew in a most lovely way; indeed, she has always, from hatching, been taller and heavier than her green brother (?). Having heard of the mishap of Mr. Rudkin, when he bred his first specimen of 94 L. A. SWAENEPOEL — INDIAN RINGNECKED PARRAKEETS albino Ringneck in California some years ago, and unwilling to risk its being killed by the foster-parents, the albino and the green were taken out of the nest at the age of four weeks, the albino showing a very slight sign of feather-plucking on the back. My wife hand-reared them nicely. They are very easy and gentle birds, and hand-rearing was no trouble at all. It is perhaps interesting to note that the albino when feeding had the crouching attitude of a female, while her green brother (?) stretched head and neck to be fed. Weights were respectively 165 gm. (for the albino) and 140 gm, on 25th May 1969, the day after the babies were taken into the house. They learned gradually to feed, first in a big cage and later in an inside aviary, they were then put into an outside aviary where the lovely tame youngsters turned into rather mistrusting birds. The albino hen and her green split blue brother (?) — he might be split for lutino, too— are now out of the country in our friend’s collection. The albino is, of course, not a common bird and, to our knowledge, the fourth ever bred. Mr. Rudkin had one killed in the nest some years ago but managed to breed a new one in 1968, I believe. Another one was previously reared at Keston Bird Farm but was lost after some months. We hope to breed more of this lovely mutation and eventually to be able to build up a strain of them. The hen is pure white with red eyes, rosy beak without any trace of black and chalk-white feet. The cock should show a black collar, presumably with a rosy lining. In the meantime we are much in trouble with our blue and split blue cocks, for which blue partners do not seem available nowadays. We have written many letters, but to no avail up till now. We are really feeling rather “ blue ” about it! BREEDING THE FIRE-FRONTED BISHOP ( Euplectes diademata ) By E. Ngrgaard-Olesen (Janderup, Denmark) For the last three years I have been the happy owner of these small, beautiful weavers, the Fire-fronted Bishops, Euplectes diademata. The male in breeding plumage has a reddish-orange forehead, the rest of the head, neck and underside black, wings blackish with feathers edged with yellow or buff, the tail ashy and the under-tail coverts golden-yellow. The bill is black. The female has the typical streaky plumage of a weaver, streaked buff and black above; throat, upper breast and flanks buff with some darker buff streaking, and lower breast and belly white. The primaries show yellow edges. The bill is horn-coloured. The non¬ breeding plumage of the male resembles that of the female. In the wilds this species occurs in a limited area of eastern Kenva and Tanzania. E. N0RGAARD-OLESEN — BREEDING THE FIRE-FRONTED BISHOP 95 According to Mackworth-Praed and Grant ( Birds of Eastern and North¬ eastern Africa , vol. 2 (1955)), the eggs, nest and habits of this species are undescribed. In 1968 I discovered a nest containing a single egg in the outdoor aviary, but I never found out which bird had made it. This outside aviary measures 4x5x2^ m., and the ground inside is covered with grass except for a third which is covered with a Juniperus chinensis. There are several branches of elm in it. There is an inside aviary, 2 x 2 x 2-5 m., and in addition the birds also have access to a greenhouse, 3 x 1*5 x 2-5 m. The greenhouse is planted with vines and wildflowers. During the winter the birds are housed in the inside aviary. At the end of May 1969 there was another nest, this time containing two eggs, plain turquoise blue, and I later discovered that the bishops were the owners. The nest was made of coconut-fibre. The only other material available to them was the grass and they used a little of this. At first it was possible to see the eggs easily through the nest, but gradually more fibres were added, until it was difficult to spot them. During incubation the male would eagerly follow the female when she was out of the nest, apparently trying to drive her back again, but she would not go to the nest in my presence. At last one young one left the nest. It was similar to the female in appearance, only a little paler, and with an almost white bill. I estimated that the incubation took about 14 days and the young left the nest when about three weeks old. The food consisted of a mixture of seeds and mealworms. The food available in the aviary was a seed mixture of many kinds of millets, canary seed, and grass-seed. As they share the aviary with different fruit-eating species they also had access to fruit and nectar, but I do not think they used much of this ; nor did they appear to touch the green plants much, but with other birds present it was difficult to observe the feeding habits. By November it was apparent that the young one was a male and it was beginning to weave nests, but was still in juvenile plumage, and at present (January 1970) has not yet moulted into breeding plumage. 96 ROSEMARY LOW — THE RED-CAPPED PARROT THE RED-CAPPED PARROT ( Pionopsitta pileata) By Rosemary Low (Sidcup, Kent, England) At the end of May 1969 I was offered three little parrots, of whose identity I was at first uncertain, until I remembered a plate in the Avicultural Magazine for October 1905. On reference to H. Good- child’s beautifully drawn and coloured illustration, I was able to identify them as Red-capped Parrots Pionopsitta pileata — two males and a female, I believed. The “ female ” unfortunately moulted out into a male. In appearance these parrots are not unlike a large Abyssinian Lovebird, the male being green, darker above, with the forehead and part of the crown scarlet, with a little scarlet surrounding the eye. The ear coverts are very faintly tinged with red. The outer edge of the wing, the pri¬ maries, and the tail are tinged with blue. The immature cock has no red on the head, except the faint tinge on the ear coverts. The adult hen also lacks the red forehead but may be distinguished from immature birds by a small area of blue on the forehead, which is not very pronounced. The total length is only 8 in., the body being rather plump, the tail short and square. The London Zoo exhibited this species as long ago as i8yy and sub¬ sequently in 1883, and 1894 or 1895. I can trace records of only two other importations into Britain. In 1904 F. C. Thorpe of Hull imported several, one of which was exhibited at the Crystal Palace show that year, gaining a fourth prize. In 1905 there were a pair at London Zoo and a single male in the possession of Hubert Astley, presumably from this con¬ signment of Thorpe’s. In 1923 Astley received two pairs and com¬ mented (Avicult. Mag., September 1923, page 2iy) that he believed that none had been imported since 1905. I was therefore congratulating myself on having acquired these little rarities when, two or three weeks later, about 20 more turned up. Unfortunately, several fanciers who had pairs of these birds lost them almost at once. I did acquire an adult hen from this consignment, a very nervous bird unlike the three cocks who are exceedingly steady, but she died after three months. A veterinary surgeon and fellow member of the Avicultural Society kindly carried out a post-mortem on the bird for me and concluded that death was due to lack of vitamin A, associated with a secondaiy yeast infection. It therefore follows that a varied and nutritious diet with added vitamins is essential. All my birds have 44 nectar ” which is made from half a pint of hot water to which has been added three teaspoonfuls of honey, two of rose-hip syrup, one of Cytacon (vitamin B12) and a few drops of ABIDEC ROSEMARY LOW— -THE RED-CAPPED PARROT 97 (multivitamin solution). The nectar is eagerly taken by the Red-caps, also grapes and apple, and any wild or cultivated greenfood in season, as well as most other fruits which are offered. They are very fond of spray millet, also peanuts, sunflower and canary seed but they ignore white millet and hemp. They are very sociable little birds, rather like Budgerigars in their behaviour in that they constantly preen each other and warble in their soft, inoffensive voices; but, unlike Budgerigars, they are gentle, sweet- tempered and peaceable. They are therefore quite perfect birds for keeping as pets. A single young one would undoubtedly quickly become tame, for they appear to have little fear of people. I put the three cocks in an outdoor aviary in June, where they seemed quite happy in all kinds of weather. In November I transferred them to an eight-foot flight in an outdoor birdroom so that they should have the benefit of electric light and longer feeding hours. Later in November, one of them begun to show the same disease symptoms as the hen which had died — tail pumping and a slight discharge from the nostrils. The temperature was around 38°F at the time so I brought the bird indoors to a living-room temperature. It soon recovered and appeared quite normal but when I returned it to the outdoor birdroom, the tail pumping started almost immediately. It would appear that this species is not really hardy so I caught up all three birds. They have spent the winter indoors and appear very fit and healthy. A pair in the possession of another fancier also showed signs of discomfort in cold weather and were brought indoors for the winter. It therefore seems that these little parrots should not be subjected to the vagaries and variations of an English winter outdoors. This species is a native of the forest regions of south-east Brazil and Paraguay. It is to be hoped that all those fortunate enough to have pairs in their possession will do their utmost to breed from them, although I doubt that a single pair would go to nest. Sociable birds such as these normally need the stimulus of the presence of at least one other pair. It would be a great shame if last year’s consignment proved to be an isolated one. 98 D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES THE BEHAVIOUR OF CAPTIVE PURPLE GALLINULES ( Porphyrio porphyrio) By D. T. Holyoak (London, England) The Purple Gallinule is a bird of extensive reed swamps and other dense vegetation of waterside habitats, and the difficulties of observation of this species in the wild have prevented studies of its behaviour. A popu¬ lation of from seven to nine individual Gallinules is kept with many other birds in the huge Snowdon Aviary at the London Zoo. These captive birds live in an open grassy area so that prolonged observations on their behaviour are readily made. This article summarizes information obtained by watching them at intervals from January 1969 to February 1970. Most of the observations were made on the grey-headed sub¬ species (P. p. poliocephalus ), but less detailed observations were made on the blue-headed, green-backed subspecies (P. p. madagascariensis) kept in a smaller enclosure. The behaviour of the two subspecies appeared to be identical. Purple Gallinules are long-legged, chicken-sized rails, with bluish plumage, heavy red bill, red frontal shield and reddish legs. The various subspecies are distributed from Spain, Africa and Asia to Australia and New Zealand, occurring mainly in extensive reed swamps and other semi- aquatic habitats, but sometimes in drier areas. Gallinules walk and run strongly, although their flight is rather weak with trailing legs. They swim strongly, but apparently only do so when pressed to escape (Falla et al. 1966, Ali and Ripley 1969). From the literature they would appear to be social birds, usually seen in parties or flocks, and Harrison (1970) has given evidence from the same captive birds as I studied showing that more than two birds are often involved in single nesting attempts. The captive birds studied appear to call less often and less noisily than this species is reported to do in the wild (Oliver 1955, Mackworth-Praed and Grant 1957, Falla et ah 1966, Ali and Ripley 1969), probably because social contact is possible in their open, grassy enclosure with less frequent vocalisations than are needed in their natural habitats. But for this difference, and certain differences in their feeding behaviour (see below), there is little reason to suspect that the behaviour of these birds differs much from that of wild Gallinules. Maintenance Behaviour Gallinules use similar behaviour patterns in caring for their plumage and soft parts to many other water and marsh birds, but they do show some noteworthy peculiarities. They bathe standing in shallow water, by making ducking movements of the head in bursts alternating with D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES 99 Fig. A. Anointing the insides of the primary feather tips with preen oil (see text). Fig. B. Sun-bathing posture, medium intensity. bursts of flapping the part-opened wings. Coots ( Fulica atra) and Moorhens ( Gallinula chloropus) also bathe when standing with their feet on the bottom of breast-deep water, resembling the less aquatic Water Rail ( Rallus aquaticus), African Black Crake ( Limnocorax flavirostris ) and Tasmanian Native Hen ( Tribonyx mortieri) in this, but differing from ducks, grebes and other water birds. After bathing they leave the water to preen and oil the plumage. Shaking movements are usually made first, then the bird nibbles its oil gland, often making rapid drinking movements in short series; then it systematically applies preen oil to the scapulars, mantle and body feathers, as it rearranges them. The tips of the part-opened wings are usually rubbed over the preen gland, apparently to oil these inaccessible parts of the body (Fig. A). The head is preened by scratching with the foot (lifted under the closed wing), only the claw of the middle toe being used. The feet are cleaned by nibbling with the bill, and the bill is wiped (some¬ times rubbed) against projections, occasionally scratched with the foot as in head scratching. Sun-bathing is commonly performed whenever the weather is at all bright, especially after bathing and the subsequent bout of oiling and preening. Sun-bathing Gallinules stand in a peculiar position with the wings extended, part-closed, on each side of the tail, or twisted downwards, or in positions intermediate between these (Fig. B). Ali and Ripley (loc. cit.) note that in India this species often clambers up reeds to sun¬ bathe in groups on misty mornings. Sun-bathing is often followed by preening and oiling of the plumage, even when bathing in water has not been carried out. Peculiar sun-bathing postures similar to those of Gallinules are also used by other rails, including Water Rail, Moorhen, Wood Rail Ar amides cajanea and Tasmanian Native Hen (pers. obs. on captive individuals). 100 D.

HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES Occasionally I have seen Gallinules sun-bathing while sitting on the ground, with their legs projecting forwards under the body, all four toes held apart and pointing forwards, and the wings closed. Feeding Behaviour The literature shows that Purple Gallinules are virtually omnivorous, eating leaves, stems, seeds, grain, flowers, insects, molluscs, leeches, fish, carrion, water snakes and a wide variety of other foods (Oliver 1955, Mountfort 1958, Ali and Ripley 1969, Falla et al. 1966, Dement ’ev et al. 1969). Captive birds were seen to take vegetable matter by nibbling low plants, pulling trailing branches down with the bill, clambering in bushes, grubbing amongst soil and ground litter, and by lifting submerged water weed in the bill. After food has been picked up in the bill it is very often transferred to the feet and manipulated with them. Food is held in the feet by apposition of the hind toe with the three closed fore-toes (Fig. C), weed is combed with the fore-toes as it is held dangling from the bill, and the feet are sometimes used to hold down large food objects while they are pecked (e.g. fish and carrion meat). Strijbos (1955) records a Gallinule eating the eggs in two egret nests in an African heronry, and I watched this species stealing the eggs from the nest of a pair of medium-sized captive babblers. The Gallinules clambered through the outer branches of a thick laurel bush to reach this nest, ignoring attacks and noisy threats from the parent babblers; eventually one Gallinule forced its way through the branches to reach the nest, and ate both of the two eggs which were in it. D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES IOI Captive Gallinules persistently use the feet to hold food when they are nibbling it, often “ wasting time ” transferring food from the bill to the feet which could have been swallowed directly. Rowley (1968) records the use of the feet when feeding on small figs picked from the ground, but suggests that this is a special adaptation to fig eating. However, use of the feet in feeding is probably of great importance to Gallinules feeding in their natural reed-swamp habitats, both in enabling them to feed from weed held above the surface of shallow water, and to feed on stems and seed heads pulled down with the bill. The behaviour has probably been retained in captivity only because it is an inherent part of their feeding behaviour, not because it is useful in these highly modified conditions. Young Gallinules attempt to hold food in their feet from when they are about two or three weeks old, and do so success¬ fully when they are half to two-thirds grown. These captive birds obtained flies and other small, winged insects by picking them from the surface of shallow water, and earthworms and snails by shovelling aside gravel with the closed bill, pushing stones aside using the frontal shield. Food of many kinds was often carried in the bill to water, and washed before it was swallowed. Tail-Flicking Purple Gallinules, like many other rails, have white under tail coverts which contrast strikingly with the darker plumage surrounding them. The patch formed in this way is used as a signal marking to warn other Fig.|D. Tail-flicking of alarmed bird. birds of the appearance of a potential predator, and it is emphasized by tail-flicking movements (Fig. D). Tail-flicking and other behaviour also functions in territorial (aggressive) display (as in the Moorhen, Howard 1940), and probably in providing a following signal for the young when the birds are moving through thick cover. Tail-flicking seems to be 102 D. T. H0LY0AK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES performed as a response to anything which frightens the bird. It is performed indiscriminately whether it happens to be preening, incubating, bathing, sun-bathing, feeding or resting at the time. Tail-flicking was also seen from birds which were apparently giving self-assertive display to drive other birds away. The Moorhen spreads the (larger) white patch on its under tail coverts in territorial threat, but does not flick its tail. In this display of the Gallinule the tail-flicking seems likely to have been derived from the alarm tail-flicking, as fear, excitement, or anger, could produce this response in both situations. Calls As mentioned above, the captive Gallinules studied seemed to be unusually quiet by comparison with the information given in standard books, probably because of the lack of cover in this artificial environment. Falla et al. (1966) list an ear-piercing screech — kwee-ow ; a draw out, almost booming poo-koo-koo-koo call; a sighing kwee-uk ; an anxious pee-ewk ; a bleating kwairk , and an agitated a-yik or k-yik call. The first of these notes is given as the bird flicks its tail in the territorial calling posture, and various ga-ga-ga or te-te-te-te calls are given in threat behaviour (and apparently during sexual display, C. J. O. Harrison pers. comm.). The vocabulary of this species seems to be highly variable, and many of the different-sounding calls merge into each other, vary considerably, or are ambivalent. Thus a detailed study will be needed to work out their functions more precisely. This variability of the calls may have an important function in promoting individual recognition in this social species, where individuals are often out of each others’ sight for long periods amongst vegetation. From the evidence of sex-identity given by mating behaviour it is apparent that the calls of female Purple Gallinules are softer and less harsh than those of males. There is a similar sex difference in the voice of other rails including the Moorhen (Howard 1940), Tasmanian Native Hen (Ridpath 1964), Coot (Rlippell 1933, Grimeyer 1943) and American Coot ( Fulica americana ; Gullion 1952). Threat and Aggressive Behaviour As with calls, some of the behaviour postures of Gallinules are ambi¬ valent, making it difficult to define their functions. However, unlike the calls, most of the behavioural postures show little tendency to merge into one another, so that they would appear to be worthy of record as a basis for future work. I have been able to distinguish three different postures used by Gallinules in agonistic encounters. The hunch-backed posture shown in Fig. E is commonly used in all kinds of aggressive encounters, especially when two birds meet while feeding. The posture is often only slightly indicated, but nonetheless sufficient to be noticed by the other bird and to cause it to respond. At higher intensities the neck is arched D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES IO3 Fig. E. Hunched threat posture. Fig. F. Gaping threat posture. Fig. G. Threat posture with tail flicking used in defence of territory. and the head thrust towards the opponent. If the opponent does not retreat then, it is usually pecked sharply on the neck or the back of the head, often in short bursts as the victim retreats and its aggressor makes short (two or three feet) runs after it. Several times I have seen an attacked bird twist its head away as if to appease when it was attacked in this way, but its aggressor pecked it regardless, causing the unfortunate bird to run away. More often when this appeasing behaviour was shown the threatened bird would be allopreened by the other, and sexual behaviour frequently followed this. Another slightly different posture is also used in threat, apparently most often when the bird concerned is not feeding, but standing close to its young, mate, or some bird which it considers itself temporarily paired to. Here the threatening bird reaches forwards without arching the neck, and makes a more or less prolonged gaping movement at its adversary (Fig. F). The aggressor’s plumage is usually sleeked when this action is used, and it is frequently aimed at birds of different species and frequently followed or accompanied by bouts of chasing, again often in bursts of a 104 D. T. H0LY0AK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES few feet each time. I have watched captive birds persistently harrying a Crowned Crane (Balearica pavonina) in this way, as well as ducks, and smaller terrestrial birds. A completely different agonistic posture appears to function mainly in territory defence. The bird stands upright and flicks its tail to emphasise the white under tail coverts, while giving loud kree or kree-ik calls (Fig. G). From their subsequent behaviour it was apparent that the birds giving this display were males on four occasions. When dis¬ playing in this way they will chase off any bird that closely approaches them on the ground, and this kind of behaviour seemed to cause periodic division of the Snowdon Aviary population into subgroups with scattered birds, those birds with the brightest plumage and reddest bills (? males) tending to be driven furthest. A display corresponding to, and probably homologous with, the “ swanning ” described for the American Coot by Gullion (1952) is used in response to disturbances near the nest or chicks, or when another bird intrudes into the nest area. In this display the bird fluffs its plumage and raises the partly spread wings over the rump (Fig. H). After aggressive behaviour, and sometimes interspersed with it, violent pecking at food objects (? redirected aggression), and bill-wiping (? an “ irrelevant activity ”) are frequently performed. Courtship and Sexual Behaviour Aggressive behaviour often merges into sexual behaviour. Slight threat posturing and slight appeasement movements probably occur whenever two Gallinules approach each other closely away from a nest, and it is the subsequent behaviour of both birds which determines whether or not sexual behaviour follows. If courtship behaviour is to follow when two birds approach each other in this way, they usually either allopreen (male preens female) or less often pass a small food item between their bills. D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES IO5 Allopreening is of importance in the preliminary sexual displays, and probably in maintaining a pair bond when it has formed. In the displays preceding mating it is always (in my experience) the male bird which preens the head and neck of the female. The female often appears to solicit allopreening by turning her head away and fluffing the neck feathers, and in these circumstances there can be little doubt that the allopreening is a ritualised activity having little to do with plumage care. Harrison (1965) discusses the functions of allopreening in birds, and shows that it has considerable importance in sublimating aggression between birds when they approach each other closely. In contrast, allopreening at the nest in the Purple Gallinule is most often mutual, and other parts of the plumage are usually preened in addition to the head and neck (except in the “ nest changing ceremony ”, see below). It was not at all infrequent to see two captive Gallinules sitting head to tail on a clutch of eggs, each bird preening the back and rump feathers of the other. Allopreening of this kind often alternated with normal preening, and sometimes the oil gland of the other bird was preened, and preen oil wiped on the feathers of both birds (four separate series of observations, including more than three different birds). It was apparent that allopreening of this kind had a significant and definite function in the care of the plumage, as the movements used appeared identical (from ranges down to three feet) to those used in normal preening, and pieces of feather scale were frequently swallowed by the preening bird. The passing of small food objects between the bills of birds which walked towards each other was seen on four different days, and each time the actions used were very similar to those of a Gallinule feeding a chick. I have seen this “ courtship-feeding ” in the pre-breeding period and during incubation, and C. J. O. Harrison (pers. comm.) has seen it performed by birds with well grown young. The infrequency of this behaviour and the small size of the food items suggests that they are only likely to be of ritual significance, and it is possible that the movements might be derived from nest building rather than true courtship feeding, as nest material is often passed from bird to bird at the nest site. A typical behaviour pattern preceding copulation is that the two birds approach each other giving slight threat display, then the female “ solicits ” allopreening, and is preened on her head and neck by the male. At this stage either or both birds may start “ walking time ”, a peculiar action where the bird walks on the spot, raising its feet without closing the toes as they usually do when the foot is lifted in walking (Fig. I). The allo¬ preening “ solicitation ” posture of the female may then be exaggerated into the sexual solicitation posture (Fig. K), and the male may step or jump on to her back and copulate. The male remains on the hunched back of the female by clinging with its feet and balancing with flapping wings (Fig. J), and mating usually lasts for two or three seconds, though Io6 D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES Fig. I. “ Walking on the spot ” in sexual display. Fig. J. Copulation. Fig. K. Solicitation posture of female. the male often remains on the female’s back for ten seconds or more, and may attempt to mate several times while standing there. The posture used by the female Gallinule when soliciting copulation is similar in many ways to those of the Tasmanian Native Hen (pers. obs.), Moorhen (Howard 1940), and American Coot (Gullion 1952). While the female bird is being allopreened other Gallinules (presumed to be males) may join in and preen on the opposite side, or from near to the other preening bird. These other birds usually continue with their preening while the first bird actually copulates, and I have not seen them make mating attempts of their own. No call is given during copulation, and the male steps off the female’s back and walks away from her, some¬ times it then preens, but not always; the female bird usually preens after a mating attempt. Breeding Purple Gallinules build bulky nests of vegetation in the wild, resembling large nests of the Coot. The nests are generally built in thick cover, and D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES IO7 usually just above shallow water, or up to a few feet above the water surface (Mountfort 1958, Falla et al. 1966, Ali and Ripley 1969). Both male and female birds share in bringing material to the nest site, but much of the material seems to be incorporated into the nest by a female bird, who receives it from the bill of a male, and perhaps other females. The captive Gallinules at the London Zoo built nests of grass under or near such ground vegetation as was available to them, and nest building activities continue right through the incubation period. Harrison (1970) has commented on the social nesting of these Gallinules and mentions a group of four birds which co-operated in the raising of a single brood. The birds of this group all carried nest material to the sites which were used for successive breeding attempts, but only one (possibly sometimes two) of the birds actually incorporated material into the growing nest structure; the others collected material, then passed it to the bird which was on or near the nest. During incubation the bird which was sitting spent considerable amounts of time plucking material from within bill reach of the nest and incorporating this into the nest walls; it seems likely that other birds incorporated material into the nest structure in this way, besides the usual one. In addition to the group of four birds mentioned by Harrison (1970) there was also another group of three in the aviary which acted as a social unit for several months during a nesting attempt, but which was less cohesive than the other group. At least three birds from the group of four, and two birds from the group of three helped with incubation, but I have the impression that the male bird which I most commonly saw mating did little if any sitting (observations on individually marked birds are needed to confirm this). All members of both groups took part in both feeding and brooding their respective groups of young (so far as I could tell), although the shares of different individuals differed con¬ siderably. From the rate at which eggs appeared in three different nests (one each day for total of six days) it would seem almost certain that each “ clutch ” was the product of a single female, as other rails lay one egg per day (Gullion 1954). Incubation periods of approximately 23 and 24 days (plus or minus one day with each clutch) were recorded for clutches of five and seven eggs from these birds. With each clutch all eggs which were going to hatch probably hatched within about a day of the first egg, despite the fact that incubation of both clutches probably started before laying was completed. Two or sometimes three Gallinules from these groups would sometimes incubate simultaneously, although most often only a single bird would be in contact with the eggs at any one time. Changeovers at the nest often involved little or no ceremony, and they were usually gradual — often one bird would join the other on the nest, then after a while the first would walk away. Most often a bird approaching the nest would bring a piece of grass or other nest material and pass it to the sitting bird, then allopreen 108 D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES the sitting bird in a very rough and stereotyped-looking way, before sitting down beside it and trying to move on to the eggs. With several birds on the nest at once it was not surprising that eggs were sometimes pushed beyond the confines of the nest rim. When this happened the eggs were pulled back by deft-looking egg recovery move¬ ments. The bill would be hooked over the egg, often slightly shivered, and the egg would be drawn back towards the sitting bird (Fig. L). At one nest a single egg rolled down a slope away from the nest and was not recovered, and the same must frequently happen in nests built in reed beds. Fig. L. Egg recovery movement. These captive Gallinules did not build substantial nest-like structures in addition to the nest which they used, but separate platforms are built in reed swamp habitats (Ali and Ripley 1969, Mountfort 1958). These platforms are used for feeding (Mountfort), and probably for roosting (as in the Moorhen, Howard 1940). Desultory platform-building attempts such as the one noted by Harrison (1970) carried out by these captive Gallinules probably represent expressions of the platform building behaviour which may be an important part of their activities in reed swamps. The captive birds were walking on firm terrain for much of the time, so that there was probably no need to build platforms. For the first day or so after hatching the young Gallinule chick remains in the nest and receives little if any food, although it is brooded almost continually. After this the chicks wander away from the nest and are brooded and fed by other birds of their particular group. At first the food was almost invariably pieces of grass bitten off and passed to them in the bills of the old birds. Sometimes adults were seen to pass food from bill to bill among themselves (see above) before feeding the young, and often food would be successively given to and taken from the young. When the chicks grew larger they were often fed on the food which was provided in food trays for the adults, including pieces of meat and fruit. Harrison (1970) suggests that the passing to and fro of food between adult and chick may serve to break it up for the benefit of the chick. When young birds are accidentally separated from the adults which are tending D. T. HOLYOAK — BEHAVIOUR OF CAPTIVE PURPLE GALLINULES I09 them they give a loud, high-pitched peep-peep-peep call which is inces¬ santly repeated until they are given attention. Chicks two weeks old were beginning to take food for themselves, but young half the size of an adult were still being fed at times, a month or so later. Acknowledgments I am grateful to P. J. S.

Thomson (Hoole, Cheshire, England) Growing vegetation is a desirable addition to any compound housing livestock. In addition to greatly enhancing the surroundings, natural nesting sites contribute to breeding success. Many plants and suitable shrubs are recommended in articles on the subject. However, with aviaries being frequently overpopulated, young plants frequently fail to become established. Very few bird keepers could tolerate aviaries kept empty while plants were allowed to make the necessary growth. It was by chance that the use of Lombardy Poplar trees proved to be very satisfactory in furnishing planted aviaries. When aviaries were constructed after the end of the war, poplar trees provided posts to help overcome the shortage of timber. Four large poplars provided 7 ft. posts up to 5 in. in diameter. The branches were trimmed from the posts of poplar, but two or three were left on near the top to act as perches. The posts were inserted about 18 in. in the soil and supported the wooden battens on which the roof netting was fixed. A lengthy nail driven through the batten and into the post top held it in position. It was a pleasant surprise to find that the poplar posts burst into buds and leaf. Not only did the poplars act as uprights supporting the roof; they developed into a dense mass of growth. This required clipping back at least twice a season, depending on how near the roof netting the plants were pruned back to. It is most desirable to prevent any shoots from growing through the netting. After a few seasons with the plants well established, the task of clipping back the growth near the roof was greatly alleviated by ring-barking the poplars about 9 in. from the top. Ring¬ barking is the removal of a J in. strip of bark round the circumference of the plant trunk down to the cambium layer. This results in the dying off of all the plant above the ring, the sap being cut off. In later years when new stumps of poplar were prepared for planting it was found much easier to remove all the bark from the top 9 in. thus preventing any growth. In addition most of the branches were left on, a bush being formed in the first season. The leaves are smaller in the first year being normal in size in the second season. Even in aviaries housing bud-eating Bullfinches, 10 to 12 recently planted stumps of poplar became established. Where only one or two were planted they frequently failed to develop, the buds being constantly pecked by the birds. Roof spans up to 30 ft. were supported entirely by poplar cuttings. After a period of four to five years a few became ineffective as roof supports, the top 9 in. having deteriorated as a result of the barking action. Generally the greater the top circumference of a cutting the longer it acts as a roof support. Anything under 2 in. in circumference was not to be relied upon but 4 in. upwards frequently T. S. THOMSON — INSTANT PLANTED AVIARIES III lasted over 15 years. It is, of course, quite a simple matter to replace or supplement any plants which deteriorate. Visitors have inquired about the cut off poplar posts pushing upwards as they grow. While there is an increase in the circumference, no upward growth of the trunk takes place. The top 9 in. of barked area does not develop in any way. Little harm, if any, is done by a few young shoots growing up through the roof netting. Usually the state of the nests in the shrubs dictates when they may be clipped back. On some occasions clipping takes place when birds are sitting without upsetting the breeding cycle. Where Bullfinches are kept the spring growth of foliage is retarded by up to a month, while the effect from Greenfinches is about a fortnight, the birds eating the earlier buds. The Poplar is so strong in growth that the buds taken by the birds are soon replaced. The only disadvantage of the retarding of the initial coming into leaf is the lateness of the provision of natural nesting sites, for the plants do not suffer any permanent damage. To offset this a few prefabricated nesting sites are provided in the shelter part of the aviaries, it being considered it is in the bird’s interest to have the early nests under cover. A few evergreen cuttings, usually laurel because of its availability, are wired into the 1 12 T. S. THOMSON — INSTANT PLANTED AVIARIES leafless Poplar plants to provide cover for early nests. While laurel leaves hang for over a year in the dead state and provide cover, care must be taken to prevent leaves falling across a nest. I have records of losses resulting from a laurel leaf falling on eggs. Poplar post cuttings inserted 3 ft. apart form a hedge. In one aviary a pair of Waterhens nested on the top and kept the growth partly under control by their continuous pecking of the leaves. The same effect was experienced when the same species nested on top of a privet hedge, the leaves being removed on top of the hedge several feet from the nest, resulting in it being unnecessary to clip the hedge all season. Privet leaves are also taken by members of the pheasant family without any apparent ill effect. However, any species which chew bark should not be enclosed in aviaries with privet. Poplars can be trimmed to provide nesting sites from near ground level. Sometimes long grasses flourish at the base and being protected they grow into the poplar foliage thus providing ideal nesting sites for low nesters such as Yellowhammers. When the Poplar cuttings have become established the trimming back results in a dense mass of foliage. When nesting is in progress it is some¬ times necessary to view through the growth with the sun on the other side, in order to detect nests. While a twice a season clipping, plus an early Spring pruning, keeps the Poplars in good shape, it may be desirable to resort to more drastic action every 10 years or so. Branches with brush¬ like tops can be cut back. The oldest Poplars are over 20 years and present no trouble to keep them within bounds. Probably restricting the growth of the foliage effects the root action on the same principle as the Japanese dwarf culture of trees. While a Poplar tree may only provide a few trunk-size cuttings suitable for the dual purpose of roof supports and aviary shrubs, all Poplars offer cuttings for striking. However, it takes several years for one to two-inch diameter cuttings to develop heads suitable for natural nesting sites. The smallest flights here with growing Poplars are only 9 ft. x 3 ft. Several flights 12 ft. x 6 ft. have a single plant at one end. Probably many would not advocate any use of live plants in such small units. It is a question of the stocking density. Here only one pair of finches occupy such aviaries. In large units the Poplars planted 3 ft. apart in rows 9 ft. distant, form continuous hedges with lanes between. It is always desirable to provide the maximum flying space in aviaries and considera¬ tion should be given to the siting of the plants. While a long narrow aviary gives the inmates a fly-way back and forth the birds must stop at each end. An aviary which provides unlimited continuous flight would be of a circular shape, not very practical to construct. Here units 20 ft. x 20 ft. provide finches with continuous flight and units 40 ft. x 40 ft. serve large parrakeets. Such desirable conditions are most frequently used by the birds in the early Spring. T. S. THOMSON — INSTANT PLANTED AVIARIES II3 It is quite a simple matter to provide live perches from the poplars by leaving individual branches unpruned. Not only is there no fixing problem, there is no need to be constantly replacing perches of the con¬ ventional type, a task the average bird keeper frequently fails to carry out properly. In addition fixing perches in aviaries results in the deterioration of the structure. How often does one observe perches supported by the ends pushed through the wire netting? The constant action of the birds alighting wears off the galvanized coating, rust sets in and the wire fractures. Where pheasants and other heavy types are kept, perches trained from poplars are most successful. Being free to yield they do not give sufficient support and the large birds are discouraged from using them. Branches cut for perches tend to become damp in wet weather and bone dry in dry weather, neither condition being normally desirable. As stated earlier, most aviaries are generally over-stocked and a planted unit can act as a test. If plants fail to flourish the answer could be too many birds. In one large unit here there is an annual “ battle ” between the gardener and the bird keeper. The aviary in question contains matured standard fruit trees, mostly apples. It is used as a breeding unit, being rested during the winter. If the birds, mostly finches, are admitted before the blossom bursts there is a loss of a ton of fruit. On the other hand, keeping the birds out of this orchard aviary greatly affects the season’s breeding results. While the actual time of commencing nesting is not really involved, the birds being accommodated in an adjacent 100 ft. x 30 ft. planted unit, the best results are obtained when the first round of young are fed on the fruit buds. The crops of the young finches are as green and fat as ripe peas in a pod. Fruit trees have two types of bud, fruit and growth. The fruit buds are plump and develop earlier. The fruit trees require an annual pruning mainly to prevent shoots from growing up through the roof netting, 14 ft. high. Poplar cuttings of the conventional type were inserted 18 in. apart to form a barrier hedge against visitors wandering through this orchard aviary, keeping them to the walk- around pathway. Planted aviaries here are much dryer than unplanted ones, probably due to root action keeping the soil open. On the other hand planted aviaries encourage vermin. I will comment on this in a later article While plants encourage insect life, it is considered a minimal fringe benefit in average-sized aviaries. Even in large units, rested in Winter, very little natural insect life is available. In one enclosure a full range of vegetables is grown, plus soft fruit. It has been found necessary to introduce blackfly on broad beans, the plants so treated being covered until the aphis had gained a hold. Three 60 ft. rows of broad and 120 ft. of runner beans are grown annually, and when infected by black and green fly give automatic success in breeding species such as Siskins. 1 14 T. S. THOMSON — INSTANT PLANTED AVIARIES In some seasons over ioo birds have been kept in this vegetable garden aviary, the results and effects providing interesting data. Non-gardening aviculturists may be deterred from attempting to root post-sized poplars. The gardening experts advice on rooting poplar cuttings is somewhat contrary to the procedure which has been repeatedly proved successful here. The cuttings whether large stumps or small shoots are inserted in early Spring, not in October or November, although this latter period is recommended by the experts. The Lombardy Poplar used here is known as Populus nigra italica , there being 35 different species of Poplar listed in the Royal Horticultural Society’s Dictionary of Gardening. THE WINGED WORLD IN 1969 By Clive Roots (Heysham, Lancs., England) Despite the usual frustrations and near-successes last year proved to be a fairly successful one at the Winged World, as we succeeded in breeding Southern Tree Pies, Brown-throated Barbets, Yellow-breasted Fruit Doves, Green Wood-hoopoes, Red-billed Hornbills, Fairy Bluebirds and Roulrouls. Many others got to the egg or fledgling stage only to be thwarted, usually by the attentions or close proximity of other birds. A pair of Little Bee-eaters tunnelled and were later seen taking live food in, but their tunnel collapsed and was then deserted. Spotted Morning Warblers made mud nests in several places, couldn’t decide which to use and laid their pale blue eggs all over the place. Hoopoes, Mrs. Wilson’s Tanagers, Andaman Grackles, Abyssinian Ground-Thrushes and Bleeding-heart Pigeons all got so very near to success also. Many interesting acquisitions were made during the year. A group of five Carmine Bee-eaters imported early in June from West Africa are still thriving at the time of writing, and have been housed in the large landscaped compartment specially arranged for tunnellers, in which the Little Bee-eaters made their effort. Groups of Ferruginous Wood Partridges, Van Den Bock’s Pittas, Spur-winged Jacanas, African Jacanas, Spur-winged Plovers and White¬ faced Tree Duck were received, and pairs of Black-throated Wattle-Eyes, Steller’s Jays, Toucan Barbets and Scimitar-bills have been added to the collection. Other interesting newcomers are Van Hasselt’s Sunbirds, Ross’s Touraco, and Grey-hooded Kingfisher. D. T. SPILSBURY — ROTHSCHILD’S MYNAH, REPORT ON CENSUS 115 ROTHSCHILD’S MYNAH (Leucopsar rothschildi) REGISTER AND REPORT ON 1969 CENSUS By D. T. Spilsbury (Malvern Links, Worcestershire, England) Because Rothschild’s Mynah has a limited distribution, being confined to certain habitat near the northern coast of the Indonesian island of Bali, the council of the Avicultural Society decided that an annual census and breeders report should be published in the Avicultural Magazine in the hope that this would stimulate interest in a captive conservation programme for the species. It should be noted that an annual census both for young bred and numbers held, was, and is conducted by the International Zoo Yearbook but this is in respect of L. rothschildi held in zoos throughout the world and does not include the numbers held or bred by private aviculturists. In 1968 the first census was conducted amongst our members, both private aviculturists and representatives of zoos, by the late Mr. W. R. Partridge, and the resulting information together with data assembled by the International Zoo Yearbook was published in the Avicultural Magazine, 75, 3, which was for May-June, 1969. It is to be regretted that Reg Partridge was not able to continue for many years the task he had set himself and for which his knowledge of this species made him eminently suitable. The 1968 census revealed a total captive population for L. rothschildi of 1 71 specimens held in 55 separate collections. In 1969 it was decided to write to all known owners informing them about the Avicultural Society’s census and asking them to complete and return a census form which in addition to the essential numerical data sought information about the species in captivity and which when con¬ cluded may suggest the best means of persuading L. rothschildi to reproduce sufficiently to represent a self perpetuating captive population. This year owners were requested to send information about the age and origin of their birds, causes of death for both adult and young stock, longevity, dispersal of surplus stock and also if willing to co-operate in a ringing scheme. Breeders of L. rothschildi were also asked to answer questions concerning the housing of breeding pairs, the type of nest box and nesting material, the number of young reared in 1969 and the prior years, the success of each pair in terms of nests, eggs per nest and young hatched per nest, and were the young removed when independent. Within the register will be found the full details of this survey but perhaps a summary and some further thoughts and conclusions will be more acceptable to some readers. There can be little doubt that L. rothschildi is an excellent choice for the aviculturist to attempt a captive breeding programme with for it is Il6 D. T. SPILSBURY — ROTHSCHILD’S MYNAH, REPORT ON CENSUS apparent that adult wild caught stock and more important aviary-bred specimens, once independent, can and do live for a reasonably long time which, of course, does mean that breeding pairs can produce young for several years. The longevity record for the species possibly rests with the birds which Mr. Ezra obtained before the last war and which con¬ tinued to live for four or five years after his death in 1956. The Zoological Society of London had a specimen for 12 years, and there are numerous examples within the register for both wild caught and captive- bred stock of specimens still living with seven, eight and nine years to their credit. It is interesting to find that of the 178 specimens held in captivity 71 are captive-bred, 64 wild caught and the remainder are of uncertain origin. Of the breeding pairs only one pair that was bred in captivity have so far reproduced and reared their young to independence, and two other owners having pairs, of which the female is captive-bred, have produced young. Within the birds of uncertain origin is the Indonesian total of 21 specimens at Jogjakarta. It would be impertinent of me, having no specialized veterinary knowledge, to draw any firm conclusions from the causes of death for both adult and immature Rothschild’s Mynahs but one or two points I must make. It is clear that not sufficient owners do bother to have their dead birds examined by skilled avian pathologists, which is a great pity, particularly in the case of young for here we have the greatest mortality. The incidence of avian endoparasites is not surprising and deaths directly attributed to Ascaridia are noted in the register. It would perhaps be wise for owners to examine faecal samples regularly and take the necessary steps should ascarids be present. I imagine that in aviaries having a natural earth floor and particularly on new sites, the gapeworm could be a problem but so far no repoits indicate that these parasites have caused death. There are several instances of mortality due to fighting both amongst the species itself and from other birds. Incompatability between a pair either seasonably or permanently must be watched for and if L. rothschildi is to be kept within a community no risk should be taken with this rare species by having more aggressive birds as companions. The production of young that leave the nest or die within it having leg and other deformities is well known in both this and other insect rearing species and they are probably due to a calcium deficiency or to a functional disorder which prevents the absorption of calcium. The large number of captive-bred specimens that fail to breed and the number of infertile eggs might also be attributed to the incorrect balance between calcium and other essentials of the diet. Readers wishing to gain fuller apprecia¬ tion of the problem would do well to consult the papers, “ Cramps and fits in carnivorous birds ” by J. D. Wallach and G. M. Flieg within Vol. 10, International Zoo Yearbook. D. T. SPILSBURY — ROTHSCHILD’S MYNAH, REPORT ON CENSUS 117 All owners were asked if they would be willing to co-operate in a ringing scheme which would make the permanent identification of all captive held stock possible. Such a system would be essential if a stud book for the species is started as indeed it is for any livestock that is to be per¬ petuated along prescribed lines over an extended period. In Great Britain, of the 34 specimens of L. rothschildi at least 12 were bred by Mrs. Scamell, mostly by one pair, and it would probably not be sensible to lose the opportunity of identifying these birds permanently before the knowledge of their origin is lost and unwitting inbreeding to a dangerous degree occurs. It was proposed that birds should be rung with split rings and young should be rung when independent of their parents. Of the 50 owners who returned their census forms, 32 were in favour of ringing (Zurich, New York, Philadelphia and San Diego operate their own schemes), Harewood and Mrs. Scamell would ring young but not their breeding pairs, two owners would not ring and 14 owners did not complete the question. In order to make the census as complete as the available information allows the following owners either have or recently had L. rothschildi in their collections and whilst most of them have been contacted none has made a return. I would be grateful if anyone can give details about these. Brown, Alfred W., Ormmond Plantation, Destrehan, Louisiana. It is believed that Mr. Brown maintains the collection of birds that belonged to his late wife and a breeding pair of L. rothschildi and their young could still be there. Lenz, W.

The Zurich Zoo sold two birds, presumed immature, to this zoo in September, 1969. (A.S.C.) The dispersal of specimens occurred mostly as the result of selling young but it is good to find that owners having odd birds are attempting to place them with owners having odd specimens of the opposite sex on breeding terms, which, of course, is the only intelligent thing to do. During 1969 Mrs. Scamell, Basle, Zurich, Milwaukee, have been able to hatch and rear to independence young Rothschild’s Mynahs and seven other owners report egg laying by their pairs. Of these successes Zurich is surely the highlight for the second generation Rothschild’s Mynah this zoo has produced in captivity. I am sure that all owners of this species will wish me to convey to Mr. C. R. Schmidt and the staff responsible our congratulations on this fine achievement. Il8 D. T. SPILSBURY — ROTHSCHILD’S MYNAH, REPORT ON CENSUS Breeding seems to have been achieved under two separate housing systems, in small flights solely occupied by the breeding pair and in very large community aviaries where a breeding pair has been able to establish sufficient breeding territory and monopolize enough of the available live food to rear young. There seems to be a trend particularly in the U.S.A. towards the single pair to each aviary method, and I agree that greater control of the nesting and rearing requirements can be achieved this way. However, the breeding of insectivorous birds from pairs housed in this way, with no need to defend the nest and an unlimited supply of food easily gathered, might account to some extent to the eviction of young that is so prevalent. Whichever way of breeding is selected it does seem that the species resents interference when rearing — or at least needs to feel secure within the nesting area, and I would assume that a planted flight, perhaps with climbing plants masking the nest, would help to create the best environment. It would seem that the species is reasonably catholic in its choice of nesting site and will utilize twigs, grasses, leaves and many other materials to line the nest cavity. The clutch of eggs can number from two to five but three and four seems to be quite normal. Instances of nesting and egg-laying cycles occurring six times in a year have been noted, but it is doubtful if more than three separate successful broods of young could be regulaily attained each year without resorting to fostering out eggs. It is difficult to ascertain the percentage of hatching in fertile eggs but one breeder in 1969 found 90% did hatch and I should expect the average to be better than 50%. I think on balance it is best to remove the young when independent, certainly from small breeding units it is essential and probably even in the large community flights breeding results would have been better had not young been present. This year, as occurred in 1968, enthusiastic breeders and owners suggested that the Avicultural Society should establish an official stud book for L. rothschildi. Official in that the studbook would be endorsed by the International Union for the Conservation of Nature and Natural Resources, and the International Union of Directors of Zoological Gardens through the IUCN’s Liaison Committee. It has always been my hope that this will be possible but I do not think that the time has yet come to embark on an official studbook for two reasons. There are still owners of L. rothschildi , particularly in Indonesia, who are not yet prepared to co-operate with us and it is essential that all owners do so, and it is by no means clear that the species is capable of becoming self-perpetuating under captive conditions. I must remind you that only four of the 50 owners that returned census forms managed to rear young. The council of the Avicultural Society will no doubt apply to the Secretary of the Zoo Liaison Committee to propose the establishment of an official studbook D. T. SPILSBURY — ROTHSCHILD’S MYNAH, REPORT ON CENSUS 119 when these two conditions indicate that the studbook could be main¬ tained. Meanwhile the Avicultural Society will continue to conduct its own census and breeders report. In 1970 we shall attempt to establish the diet for the successful rearing of young and general feeding for the species, try to determine the best way of sexing Rothschild’s Mynah and continue to seek information concerning mortality for the species. I would like to express my gratitude to all who completed and returned their census forms ; in this day of bureaucratic spying through form filling, it must come as a severe blow to find the practice has extended to one’s pastime !

The original pair was purchased before 1965 and was wild caught. Young were hatched in 1965, 1966 and 1967, but were killed by the adult male between 6-13 days. In 1968 the male was removed from the flight after eggs were laid and kept out of sight and hearing of the female. The female reared one youngster to independence (two hatched but one died at ten days) and this was removed. The male was returned and the pair bred again but though young were hatched the female would not feed them. In the spring of 1969 the male killed the female and the young hen was placed in an adjoining flight. Later the young female was allowed to join the adult male. Two eggs were laid that contained young. The breeding flight was planted and had dimensions of 2 m. long, 1*20 m. wide and 2 m. high, the shelter was the same size.

Nest boxes 15 x 12 x 7! in. with a square entrance hole z\ x 2^in. and an outside landing ledge. Nesting material mostly fine twigs and roots with some grass and feathers. Fresh green leaves were also found in the nesting cavity. The cause of death for young is the usual rejection by the parents. Within 24 hours of hatching the young would be thrown out the nest. From previous years it has been found this procedure would continue until late summer and the last nest of eggs would be hatched and the young more usually reared. Mr. Hall suggests that the success comes after the peak in breeding condition is over. Pair 1 nested three times and pair 2 three times, the clutch for each pair being usually four eggs but sometimes three or five. In 1969, whilst the two pairs were still with Mr. Partridge, an interesting experiment in the use of foster parents was tried. Three pairs of common Starlings, Sturnus vulgaris, were housed in a large flight and allowed to nest at the same time as the Rothschild’s mynahs. Eggs were transferred from the mynahs to the starlings but rejection of the hatched young, of both species, took place from the starlings nests. A second attempt was made and eggs were again transferred. Just before hatching a panel in the aviary roof wire netting was removed to allow the starlings to forage for their own food but two pairs and one male promptly decamped. The remaining female hatched two young mynahs and reared them on her own but never leaving the aviary to do so. One youngster died just before it left the nest and the other died about a week after leaving the nest, dietary deficiencies probably accounting for these losses. In 1969 approximately 90% of the eggs hatched. I am grateful to Mrs. A. B. Partridge and to Mr. A. E. Hall (Mr. Partridge’s assistant) for most of this informa¬ tion. King, G.
