Pappas Introduction Over the past 23 years I have, as a large part of my avicultural activity, kept Chinese Painted Quail. During this time I have taken the opportunity to make observations and report on their varied behaviours (Pappas, 1996). One of the most fascinating behaviours involves the vocalizations made by both the male and female quail when they are engaged in nesting activities. My purpose in this paper is to describe and show how the Chinese Painted Quail’s calls, nest building and egg-laying activities are related. The Chinese Painted Quail Coturnix chinensis (Sibley & Moore, 1993; synonymous with Excaifactoria chinensis ) is an Old World quail found in counties such as China, the Philippines, Indonesia and other areas of south-east Asia, south to parts of northern and eastern Australia, where it is known as the King Quail; Clements (2007) calls it the Blue-breasted Quail. It is small enough to fit in the palm of a hand. As well as the natural or normal-coloured form, as an avicultural subject, it is propagated in a variety of colours such as silver, cinnamon and white, with the males having different bib colourings. Among this quail’s more charming behaviours is the delightful tidbitting call between pairs. However, other vocalizations are important because of their association with particular behaviours, including nesting activities. The male is the more vociferous of a male-female pair, although the female Chinese Painted Quail will, at times, call. During an impending reproductive cycle, the female will find a suitable, inconspicuous place, to make a nest in which to lay her eggs. As the clutch increases in size, it is noticeable that the male and female pay attention to keeping a lookout for any possible disruption to their nesting activity. A wide variety of calls are made by the male and female with respect to various activities they share, such as tending to the nest and the clutch of eggs. 162 PAPPAS - CHINESE PAINTED QUAIL In my study, I was interested in determining the connection between nesting activity, vocalization and egg-laying. As it happens over a period of a few days, I noticed that I could anticipate when the next egg would be laid - which was approximately 25 hours after the previous egg had been laid - by the increase in calling by both the male and female. From this, I decided to try to ascertain more precisely the relationship between nesting activity, vocalization and egg-laying. Methods The Chinese Painted Quail I chose for my study was my first pair of quail. According to the place where I purchased them, the pair had been together all along and the female had not laid eggs in the past year. The birds were silver in colour, with the male having red eyes. Both birds weighed approximately 45g each. During the period in which my observations were made, my quail used two different nest sites within their large cage. The first nest site was not bolstered by other structures I might have added for them, while the second nest site consisted of a small, square, woven basket in which the female felt secure and therefore accepted the site for laying her eggs (see photo p. 1 63). My quail were kept in their cage in a relatively quiet spot where they would not be disturbed but could be readily observed. The observation period was from January- July 1 987, which amounted to just over six months. During this period, the date, the time of male crowing, the time of female crowing and the time of egg-laying were all recorded. These data were recorded at all hours of each day. The data were analysed to determine the relationship between vocalization and egg-laying. In addition, detailed observations were made of their nesting behaviour with regard to vocalization and egg-laying. Results A total of 1 , 1 43 calls were heard from the male and 720 calls were heard from the female. A total of 65 eggs were laid. During the six month period, the data were compiled and plotted at one hour intervals (see Fig.l). From midnight to 5.00am, crowing by both the male and female was at a minimum. Peak calling by the male occurred at two different time intervals, one between 7.00am-8.00am and the other between 7.00pm-8.00pm (1 9.00hrs-20.00hrs). Peak calling time for the female was between 9.00am- 10.00am and then diminished from 10.00am to noon, followed by a level of relative stability, albeit with some oscillation in the amount of calling from approximately 1.00pm- 10. 00pm (13.00hrs-22.00hrs), with peak egg production occurring at4.00pm-5.00pm (16.00hrs-17.00hrs). Calling by both the male and female PAPPAS - CHINESE PAINTED QUAIL 163 My Chinese Painted Quail at their second nest site in a basket. diminished at peak egg-laying time, after which calling by the male increased sharply, but calling by the female did not increase as much (see Fig.l). The male’s peak calling occurred approximately six hours prior to the start of egg-laying and the female’s peak calling time occurred approximately four hours prior to the start of egg-laying (see Fig.l). When egg-laying was in progress, the male’s calling rose to a second peak from late afternoon to night. Calling by the female was below its peak during the entire laying period. There was a higher number of calls by both the male and female at the start of the egg-laying period, these then dipped at the maximum egg-laying time, then increased in the time interval just after the maximum egg-laying time (again see Fig.l). Nest building activities and nesting behaviour On November 23rd 1 986, 1 bought a pair of silver Chinese Painted Quail. Three days after I brought them home, the male began to call. It was not until January 14th 1987, that the female began to call. It was evident from the beginning that the two quail were very devoted to each other. From January-March 1987, both the male and female engaged in nest building activities, much of which consisted of scraping or digging a nest by kicking and fluttering materials to make a depression on the floor of the cage. At one point, when the male was standing next to her and was facing 164 PAPPAS - CHINESE PAINTED QUAIL Fig.l . Comparison of time of number of eggs laid to number of crows by the male and female Chinese Painted Quail. her, the female pecked his left leg. He moved away from the nest and the female carried on nest building and continued to keep the male away from the nest. Even after feeding not far from the nest, the female returned to the nest site to prevent the male from approaching it. When feeding, the female took pieces of vegetables and threw them over her shoulder into the nest area around her. She continued with her nest building activities, feeding in the same way and pecking the male’s back or legs to send him away from the nest. Not long after this, the female settled down in the nest and laid her first egg on January 20th 1987. Both the male and female called out. The male stood at the left front of the nest. The female continued her nesting behaviour and tried to roll an egg under her breast. She also continued to peck the male when he was near the nest. However, the male walked around the female in the nest a number of times and had done so even when she was in the process of laying an egg. At times, the female left the nest and paced about with the male. She then returned to the nest and continued with her nesting behaviours. Both the male and female continued now and then to dig at the nest site. I have witnessed the male engaged in egg rolling behaviour and throwing food over his shoulder to the nesting site. The male was active at the nesting site, engaged in tidbitting and making a variety of calls, including a preening call, a rapid, high-pitched “ whit-whit ” call, a cricket call and a crow call. PAPPAS - CHINESE PAINTED QUAIL 165 In and around the nest, the male made a nesting call, that was a bubbling sound or a series of' “whoooos” while scraping out the nest. The female also called and usually made a two-note high-low call or soft “peeping” single notes. The male was very attentive towards the female despite her sometimes pecking him. He stood near the nest keeping a lookout while the female ate seeds. Even when the female was away from the nest, the male would go over to the nest site and stand near it keeping a lookout. From April- July 1987, the pair had a square basket which I had placed in the cage for the pair to use as a new nest site. Almost Immediately after I had placed it in the cage, the female began to throw pieces of vegetable over her shoulder into the basket. However, the first egg was laid between the old nest site and the basket. When the female slept in the basket, the male was exceptionally quiet and moved very slowly. Finally, the female laid an egg in the basket. At that point, the male stood very still near the basket, turning his head from side to side scanning the area. Shortly afterwards, the male went to the old nest site and did some calling. The female subsequently proceeded to lay an egg at the old nest site. Eventually, the female returned to the nest basket. She continued to frequent the nest basket and lay her eggs in it. The male positioned himself in front of the nest basket or walked around with his body stretched tall and kept a lookout, but sometimes went to the old nest site and called. After a few hours, the female and the male returned to the old nest site and commenced to engage in nest building activities and feeding. Egg-laying then proceeded at the old nest site. Towards the end of April, the female returned to the nest basket to lay her eggs. The male would be positioned to the left or right of the front of the basket and would remain very still. The nest basket continued to be the place for egg-laying and nesting behaviour through until early July 1987. Discussion Studies such as this one are important as little recent information has been published in ornithological research journals on the behaviour of this particular Old World quail Some of what is known about the natural history of the Chinese Painted Quail and related Coturnix species was obtained by late nineteenth century and early twentieth century aviculturists (e.g, Butler, 1897; Meade- Waldo, 1898; McGregor, 1909; Finn, 1 9 1 1 ; Hopkinson, 1926; Hachisuki, 1931), because it was difficult to find and observe these small quail in the wild. As the Chinese Painted Quail became more popular with aviculturists, more observations and information on its behaviour was published in the mid-late twentieth century (e.g. Delacour & Mayr, 1946; Johnsgard, 1988; Alderton, 1992), especially in journals such as the 166 PAPPAS - CHINESE PAINTED QUAIL Avicultural Magazine (e.g. Seth-Smith, 1957; Yealland, 1962; Harrison et al. 1965; Harrison, 1965, 1968, 1973a & 1973b; Robbins, 1979; Pappas, 1996). Chinese Painted Quail produce many kinds of calls for particular purposes. During heightened interest in reproductive activity, a variety of calls are uttered, some of which may be interpreted specifically with respect to nest building, egg-laying and incubation. In my study, both the male and female called when engaged in nest building and egg clutch activities. The crowing call is usually uttered in the morning and evening and when the male and female are not within sight of each other. However, in my study, when the female was incubating eggs, the male uttered the crow call, which may have been his announcement about his status with the female. The male called to announce to all that he was not only with his female companion engaged in the reproductive cycle, but also that other males should stay away. The female called at times, seemingly to announce that soon another egg would be added to the clutch. The male also uttered the low volume call just prior to the crow call, especially when the female was sitting on eggs. He would travel to the farthest extent of the cage and utter the low, hoarse call. I have observed this a number of times with various pairs of quail (Pappas, 2001). During nest building, Chinese Painted Quail act in a similar way to Bobwhite Colinus virginianus (Stokes, 1967), Gambel’s Quail Callipepla gambelii (Ellis & Stokes, 1966) and the Chukar Partridge Alectoris chukar (Stokes, 1961). As with other quail, my quails’ behaviour of taking food and throwing it over the shoulder was their means of bringing materials to the nest, rather than carrying such materials via the beak. Scraping the ground and lobbing materials to the nest site are part of the display performed by the Chinese Painted Quail. Just as with other quail, such as the Bobwhite (Stokes, 1967), nest scraping or digging by my Chinese Painted Quail, was accompanied by a nesting call. Although the call varies from species to species, there is no mistaking the particular call and its association with nesting activities. It is usually a series of short, soft or low notes. The nesting call and associated nesting behaviours leading to egg-laying are among the most important activities in the life of the Chinese Painted Quail. From data recorded on vocalizations, the peak calling time between 7. 00am- 8. 00am represents the morning calls that can be expected from the Chinese Painted Quail. The evening vocalization period represents the usual time for this to occur. Most importantly, during maximum egg- laying, vocalizations by both the male and female diminish. This indicates a potential predictor for egg-laying, whereby there is an increase by the male PAPPAS - CHINESE PAINTED QUAIL 167 in vocalization one hour prior to maximum egg-laying and two hours prior to maximum egg-laying by the female (see Fig.l). Conclusion Careful observations along with noting the times of the Chinese Painted Quail vocalizations provided a way to anticipate and, potentially predict, the time of egg-laying. The same seems to be true with Bobwhite, GambePs Quail and the Chukar Partridge, and it would be interesting to learn if this is the case with other species of Galliformes.

THE TROPICAL SCREECH OWL Megascops choliba by Peter Stocks 169 The Clements Checklist of the Birds of the World Sixth Edition (Clements, 2007) lists 24 species of screech owl Megascops spp. and numerous subspecies. The screech owls are to the New World what the scops owls are to the Old World and until very recently both were grouped together in the genus Otus ; indeed in many publications the screech owls can still be found listed in the genus Otus. The screech owls inhabit a diverse range of habitats, being found not only in forest, but also in deserts, dry savannah, woodland, parkland and gardens. They seem to fall within the size range 7 Vain- 1 1 to (approx. 19cm- 28cm). Some are more stocky than others and appear somewhat larger. The Western Screech Owl M kennicotti is a good example of this. The Tropical Screech Owl M choliba , which is found from Costa Rica southwards through northern South America, reaching as far south as northern Argentina and Uruguay, is about mid-range in size. Clements (2007) lists nine subspecies. In addition, the Tropical Screech Owl is polymorphic, with the three most easily distinguishable morphs (colour phases) being the greyish brown, brown and rufous (there are also intermediates). Restall et al. (2006) illustrate three subspecies and deep rufous, rufous, light brown, dark grey-brown and a very dark so-called black example of the plumages of this owl and note that there is considerable variation within morphs, subspecies and local populations. The facial disc of the greyish brown morph is lightish grey with a broad black border and the crown of the head and upperparts have heavy dark streaking. The plumage of the underparts is finely vermiculated with brownish buff and has vertical black streaks, each with four or five finer lines running horizontally through them and creating a fishbone-like pattern. The tail feathers are mottled and have fairly indistinct barring. The eyes are a dirty yellowish colour and both the bill and cere are greyish green. The talons are horn-coloured with a blackish tip, though not necessarily all of them (I have had specimens with one or more lacking this coloration). The brownish morph has predominantly brown plumage, with dark brown streaking and the other dark coloration also this colour. The rufous morph is a most striking looking bird with rust-coloured plumage. As far as habitat goes, the Tropical Screech Owl seems to prefer open forest, savannah and woodland. Indeed, although it pains me to say so, this is a species which may have benefited from, dare I say It, deforestation, which has opened up new clearings and promoted secondary growth. In towns and 170 STOCK - TROPICAL SCREECH OWL cities across its range, it is often found in parkland, where it may be seen perched in trees and bushes. During the breeding season birds will often roost together (I have observed with my own pairs that one will often lean up against the other) but at other times roost singularly. Although observing its behaviour in the wild must be fraught with difficulties as it seems to be strictly nocturnal. The Tropical Screech Owl was first imported into the UK in the early 1970s and Twycross Zoo is known to have had two in 1972. They later proved to be a pair, that was initially housed in a cage approximately 4ft x 2ft x 4ft high (1 .2m x 0.6m x 1 .2m high), along with a Spotted Little Owl or Spotted Owlet Athene hrama , in what I believe at the time was the children’s section of the zoo. Apparently no serious attempt was made to breed the Tropical Screech Owls prior to 1 976. In April that year a broken egg was found on the floor, after which consideration was given to providing them with more adequate accommodation. An aviary was constructed for them which measured approximately 8ft x 5ft x 6ft high (2.4m x 1 .5m x 1 .8m high) and had a 8ft x 3ft (2.4m x 0.9m) wire mesh viewing panel the width of the aviary, but was otherwise completely boarded, including the roof. For some unknown reason, not only was the pair of Tropical Screech Owls transferred to the new aviary, but also the Spotted Little Owl or Spotted Owlet, and all three birds shared a nest log. In May 1977 an egg was laid, but despite this, all three owls were left together in the aviary. A few days later disaster struck when the bottom of the nest log gave way and a smashed egg was found on the floor. The log was repaired and put back in place and soon afterwards a second egg was laid. Yet again, however, catastrophe reared its ugly head and the bottom of the nest log fell out again (how could this have been allowed to happen?). Following this a more conventional wooden nest box was provided and was readily accepted. The next time two eggs were laid and it was noted that the Spotted Little Owl or Spotted Owlet remained in the nest box throughout the incubation period, though it is not known if it played an active part. A policy of non-interference seems to have been adopted and although the first egg was scheduled to hatch on June 13th, it was not known for certain whether the eggs were fertile and whether or not they had hatched. A belt and braces feeding regime was adopted and the amount of food was duly increased. It should be noted though that this species tends to be a somewhat voracious eater and an increase in food consumption is not necessarily an indication that there are chicks in the nest. However, on July 1 6th a chick finally appeared at the nest hole and later fledged successfully. Dave Coles (1986) listed it as the first successful breeding of this species in the UK. STOCK - TROPICAL SCREECH OWL 171 Following this successful breeding, the Tropical Screech Owl seemed to disappear from the avicultural scene and nothing more was heard of it until a farther importation in 1991, of birds that were direct descendents of founder populations in Canada and Germany. The birds were said to have originated from Paraguay. If this was true (and it is not a hundred percent certain that it was) then they likely belonged to the nominate subspecies M c. choliba. In my own collection I used to keep the grey and brown morphs of this delightful owl and always paired grey to grey and brown to brown, but I now keep only the brown morph. I am given to understand that there are some examples of the rufous morph in Germany, but I am currently unable to verify this. Where I live in East Anglia, here in the UK, we are often prone to quite bitter easterly winds coming in from the North Sea, but at no time do my birds - despite their name - show any signs of discomfort. They are housed in aviaries measuring some 4ft 6in wide x 9ft long x 6ft high (1 .4m wide x 2.8m long x 1 .8m high). The rear third of the roof is covered with corrugated perpex sheeting and the back and one third on each side of the aviaries is, on the top third only, boarded, but the remainder is open to the elements. However, dependent on the position of the aviary or aviaries, it may in some circumstances be prudent to use polythene sheeting or some similar material to provide extra protection, especially if particularly severe weather is anticipated. I provide a nest box Sin x Sin (20cm x 20cm) square and approximately 1ft (30cm) high at the front and 1ft 4in (40cm) high at the back, with an offset hole approximately 3 in (7.5 cm) in diameter. In the bottom of the box I place a substrate of wood shavings on which the female lays a clutch of three to four rounded eggs which measure approximately 33mm x 30mm. Incubation commences after the second egg has been laid and lasts for approximately 28 days. The young fledge at approximately four weeks of age and are independent a farther four weeks after that. Once they have acquired adult plumage, at about three to four months of age, they can be surgically or DNA sexed. References Clements, J. F. 2007.

It is poorly known and generally regarded as probably being rare. It was first described in 1 862, but for nearly a century scientists and ornithologists alike confused it with the Grey Seedeater S. intermedia. Both taxa had the name Grey Seedeater Spermestes grisea. It was not until 1923 that they were finally recognised as distinct and separate species. The specific characteristics that separate the Slate-coloured Seedeater from other grey seedeaters are its orange bill, the white marks on the sides of the throat, the white half-wing-bar and its greenish olive legs and feet, with pale coloured nails. It is apparently normadic, flying in flocks high over forests and wooded foothills, looking for flowering or seeding bamboo. It flies all along the Northern Cordillera of Venezuela and we have twice seen it in our garden in Santa Paula, in Caracas. On one occasion a bird flew into the house in an attempt to join the birds singing in the laboratory. Like all birds that are associated with seeding bamboo, it can be common for a few months, but then disappear. Most birds that are seen in bamboo-free locations are in transit, i.e. passing through. Its exact relationship with bamboo is unclear. Unlike most Sporophila seedeaters it has a peculiarly-shaped bill with a sickle-shaped upper mandible only one third as deep as the larger, lower mandible; it also has rictal bristles (see Fig. 1). The construction of the bill suggests it is adapted for dealing with hard bamboo seeds Chusquea sp., while the rictal bristles suggest it catches and consumes insects - presumably those found on its preferred species of bamboo. I have seen it hawking insects in my aviary and searching the leaves of the Ficus , apparently looking for insects. Most individuals will readily take mealworm larvae and pupae, but ignore the beetles. They will also nip out the emerging buds of Chusquea bamboo growing in the aviary - to such an extent that three Chusquea bamboos I was attempting to grow, were all killed by these seedeaters. Over a period of more than 1 0 years, I studied specimens in museums in Europe, North America and here in Venezuela. I gathered information from birders, bird keepers, trappers and bird sellers, but considering the depth and breath of my investigation, I came up with very little information of real RESTALL - SLATE-COLOURED SEEDEATER 173 value. By far the most rewarding part of the project was obtaining live birds and keeping them in the laboratory and aviary. Many birds were kept for varying periods during the six years of the study, some for only a few months and a few for as long as five years. The total numbers of individuals studied was more than 70. As the study progressed, I carefully made measured drawings of most of the birds - some of different birds together and others of particular birds - and, as time passed, repainted them again and again. Summary Both sexes of the Slate-coloured Seedeater have three distinct and separate plumage phases. These are juvenile, intermediate and adult. The progress of the female’s plumage is predictable and variations are slight, probably within the allowance of individual variation. However, the male’s plumage becomes increasingly variable with age and that of adult males can range from the common grey and white bird illustrated in field guides, to morphs that can only be identified as S. schistacea by the shape of their bill and their song. The illustrations on pp. 174-175 show the development of the plumages of some individuals and give an indication of the range of variation. The chart on p. 178 shows at a glance how the plumages develop from juvenile to intermediate to adult. Juvenile Six different juvenile plumages are shown at the top of p 174 Most juveniles have either warm brown or warm grey upperparts. The bill is dusky coloured, as are the legs, feet and nails. These two forms are sufficiently distinct and frequently occurring to be recognised as two separate morphs. The third has citron-olive plumage very similar to the first intermediate plumage and, unless the bird has a yellow fleshy gape flange, it is not possible to tell whether it is a juvenile or an immature bird. Alas, I have no certain evidence that the citron-olive morph has a juvenile female plumage. Some of the individuals I painted were clearly recently fledged, as shown by the flange of yellowish skin at the comers of the gape. Intermediate female The next group of birds (below) shows the progression of two different females. The bird on the left goes from juvenile to a yellow-bellied citron- olive intermediate plumage (centre) and then into its first adult plumage (on the right). The bill of the young juvenile female is entirely dark brown, but after a few months shows a characteristic orange to hom-coloured spot under the bill The dark, usually uniform coloured undertail-coverts, appear to be a characteristic of female plumage, although 1 have not had sufficient specimens, that were subsequently confirmed to be females, to be positive about this. Most males in intermediate plumage have pale, ticked 174 RESTALL - SLATE-COLOURED SEEDEATER RESTALL - SLATE-COLOURED SEEDEATER 175 176 RESTALL - SLATE-COLOURED SEEDEATER or cinnamon undertail-coverts; the cinnamon is a lighter and warmer colour than the dull brown of the female’s undertaibcoverts. Intermediate male Males enter the intermediate plumage phase alongside females of the same age. The intermediate plumage though usually extends through several moults and several distinct phases of development. Many birds showed at least two distinct intermediate phases and most showed three, some others showed four or more. The third group of illustrations (at the foot of p. 1 74) show part of a series of studies over several years of a male, that follow it from juvenile (upper left) through the first dull citron-olive phase to the bright middle intermediate phase, when the amount of orange on the bill is increasing from the base towards the tip. By the time the bird has acquired the third intermediate plumage, the orange on the bill is brighter or richer in colour, but the plumage is paler and less greenish above. The yellow below has some white mixed in with it, and the amount of white increases in the next plumage. By the sixth plumage in this sequence (lower right) the bird is clearly showing emergent basic adult plumage; the bill is now entirely orange and touches of black and white are showing on the face and throat. If one of the wings is spread and the primary coverts are pushed to one side, a small amount of white may often be seen at the base of the primaries, as was the case with this particular bird. The progress of the ‘butterfly’ male The fourth group of illustrations (at the top of p. 175) show how the plumage of an individual male goes through a continuing development - that continues after it acquires its first basic adult plumage and on through the life of the bird. Note how all the characteristics of the basic adult plumage are apparent in the case of the first bird in the middle row (bird No. 4). It is only when the bird is almost three years old that the small patch of white becomes apparent at the base of the primaries. In the following two plumages, the basic plumage becomes increasingly clear and definitive. The first bird on the bottom row (bird No. 7) has begun to show a plumage pattern that goes beyond the basic definitve plumage - with the white marks on the sides of the throat now extending from the chin to the sides of the neck and with more white appearing on the wings; this bird had three wing-bars - it was the only time I have seen this. The fully adult male usually shows only a partial wing-bar, formed by the terminal white edges of the innermost four, or more rarely five, median wing-coverts. The following year (the bird was now five years old) the white had begun to encroach upwards onto the sides of the breast. By the time the final drawing on the right-hand side of the bottom row was made, not only had the small patch of white at the base of the primaries disappeared, but the amount of white on the sides of the throat RESTALL - SLATE-COLOURED SEEDEATER 177 and on the sides of the breast had dramatically increased. Bird keepers in Venezuela who specialise in keeping this species, say that this is a very rare variety and is known amongst them as El macho Mariposa (the butterfly male) and is highly prized. A photograph of a bird sent to me a few years ago by Hennning Pust in Denmark was an example of this morph. Adult male polymorphism The final group shows eight adult male plumages, painted from live, wild birds. These are birds that were brought to me when they were already adult or moulted into these plumages while in my aviary or laboratory. They are not one-off plumages, as I have seen each one a few times, or many times, on different occasions. Nonetheless, the grey male, the first bird on the top row (bird No.l) and the bird on the right in the middle row (bird No. 6) are the common ones that are usually seen (the solid olive cast to the grey plumage is not noticeable in the field). Note also that the two birds on the bottom row (birds Nos. 7 & 8) are extremely unusual and very unlike the typical grey bird. But this is not the definitive set of morphs or variants - according to bird keepers here in South America there are up to no fewer than 20 different varieties recognised within the bird keeping fraternity. They include birds with long, forked tails and birds with short, square-cut tails, ‘dwarfs and giants' 10cm (approx. 4in) and 13cm (approx. 5in) in length from the tip of the bill to the tip of the tail, for example. All are morphs I have found occurring along the northern part of Venezuela. Plumages chart It is easy to see in the first box (on the following page) the three basic juvenile plumages that occur. There is never any white at the base of the primaries in any of the juvenile plumages. The colour of the undertail-coverts is variable (inconsistent). The bill is typically Sporophila in profile, but is 1 Q%~ 1 5% smaller than that of the adult; the shallow, scimitar or scythe-shape of the upper mandible is apparent and identifies the species, should there be any doubt. The legs, feet and nails are dull to greyish brown to dusky. Listed in the next two boxes are the intermediate plumages. In her first intermediate plumage, the female moults into the same citron-olive colour as the male, but is distinguished from him by having all-dull brown undertail-coverts. The legs and feet may lighten and become more greyish to olivaceous grey and the nails may lighten to a kind of horn colour. The bill is dusky with a small area of horn colour under the base. The male usually has an extended intermediate stage, passing through three morphs, or, if the entire intermediate stage is regarded as being citron- olive, then there are usually three phases to this morph. In the second of these phases, the plumage is surprisingly bright. The belly is bright citron 178 RESTALL - SLATE-COLOURED SEEDEATER Plumages chart Juvenile Three morphs h Warm brown 2.

The soft parts do not change with each moult, but change gradually from dusky with a pale horn coloured patch under the base, becoming increasingly horn-orange around the base of both mandibles, through nearly all-orange with a dusky tip to finally all-orange. The colour of the legs, feet and nails also change gradually, the legs and feet becoming olive-grey and the nails becoming increasingly pale to pale horn colour with some older birds. There are though also individuals with dull coloured legs, feet and nails, that continue through into adult plumage. In the final two boxes, it can be seen that the female returns to a cryptic brown colour, with a whitish to buffy belly and an all-dusky coloured bill. The legs, feet and nails are variable in colour. In contrast, the male may moult into the plumage of one of several morphs. At one extreme is a medium grey morph, with a white belly and yellowish bill and looking for all the world like the Grey Seedeater S. intermedia. I have even had birds in this plumage with brown legs, feet and nails, and it was only the characteristic bill shape that confirmed their identification. At the other extreme is the dark charcoal coloured bird, with a very clearly defined white belly and with white markings on the throat and wings, a rich orange coloured bill and green-olive legs and feet and pale yellow nails. The only characteristic of adult plumage which is constant in the male is that the coloration and pattern markings invariably intensify with each year that passes. Fig.l. Bill colour of Slate-coloured Seedeater. 1 . Juvenile: bill entirely dusky; 2. & 3. Intermediate: bill initially dusky but with increasing amounts of yellow-orange; 4. & 5. Adult male: bill clearly showing line of the cutting edge. Note also the rictal bristles. Conclusion It seems undeniable that the Slate-coloured Seedeater is polymorphic. I have not been able to examine the types of the various subspecies described, but from photographs, descriptions and measurements, all fall within the 180 RESTALL - SLATE-COLOURED SEEDEATER range of taxa found in Venezuela and, therefore, it seems to me equally undeniable that the species is monotypic. This study and the findings would have been impossible without the use of avicultural skills and experience. Every effort was made during the six years of the study to maintain the birds in as natural conditions as possible, with exposure year-round to local hours of daylight, sunlight and rain. As feeding was of great concern, fresh growing grasses that were in seed were offered regularly, including green rice on the stem, collected fresh from the rice fields, and a wide variety of seeds. Insects were also offered, as was a brand of softfood imported from the USA. Aviculture This species is well-known but is uncommon in aviculture outside of South America. It is popular amongst specialist birdkeepers in some South American countries. It is apparently bred regularly in Brazil, where it is said to do best in an upright cage. Birds from northern South America (mostly from Venezuela) are (illegally) taken across the border into Brazil, from where they are exported to continental Europe, where this species is favoured by Sporophila specialists. The male has a strong and persistent song and is a showy and active bird in an aviary. When in breeding condition, he will chase all other yellow- and orange-billed birds and, at times, almost any other bird he perceives to be invading his territory. The female builds a very small, neat, cup-shaped nest and, in my experience, will readily use coconut fibre to make the cup of the nest, subsequently surrounding it with fine grass rootlets and odd strands of grassy vegetation. She lays two, or more rarely three, pale, slightly bluish eggs, speckled with browns, including umber, slightly more densely at the broad end. Incubation begins after the second egg is laid. The female can become very nervous and I have lost clutches of eggs and young nestlings, which I have found on the floor beneath the nest, or at the far end of the laboratory or aviary, presumably as a result of minor disturbances. As with other Neotropical grassfinches, the young fledge early (after 12-13 days) and the precocious fledglings hide low down in cover for the first few days and continue to be fed by their parents.

E-mail :robinrestall@gmail. com EXPERIENCES BREEDING THE WHITE-THROATED MAGPIE-JAY Caiocitta formosa IN SOUTH AFRICA 181 by F. C. Barm coa t A noteworthy collection of soft-billed (i.e. non -seed-eating birds) and an excellent facility for breeding them have fairly recently been built-up by Graeme Hoffman on his 12 acre (approx.5 hectare) property on the north- western side of Johannesburg. About l,200sq m (approx. 13,0Q0sq ft) are now under aviaries and there are 80 enclosures of varying sizes, as well as a well equipped kitchen for food preparation, a hospital room in which birds that fall ill can receive instant attention, breeding rooms for mice and mealworms and rooms for food storage. Graeme has bred birds since he was eight years of age, beginning with finches and progressing to quail, pheasants and waterfowl, and then onto the African Grey Parrot Psittacus erithacus and South American parrots. About 12 years ago he began to become interested in breeding softbills, spurred on by the advent of the commercial availability in South Africa of excellent proprietary foods, which greatly simplify the feeding of such birds. Expertise in breeding these types of birds has increased astronomically and with their great variety of forms and behavioural patterns, they provide a challenge and are a never ending source of interest. Furthermore, these groups of birds seldom destroy aviary vegetation and can, therefore, be housed in aesthetically pleasing aviaries. This fits in well with Graeme’s professional expertise as a nurseryman and his business, a home-based landscaping service, that specialises in indoor plants. Wisely in this softbill breeding facility there is now a focus on certain groups of birds, namely jays, toucans, barbets, rollers and hombills. With the jays the greatest breeding success to date has been achieved with the beautiful and incessantly active White-throated Magpie-Jay from Central America. There were some very interesting aspects to the breeding of this species. Two pairs became available four years ago. Because the White-throated Magpie-Jay is known to live in flocks and to be a social nester, with several members of the flock feeding the young in the nest and after they leave it, all four were initially house together in a fully planted aviary measuring 7m x 1 .2m x 2.4m high (approx. 22ft 9m x 4ft x 5ft high). The roof of the aviary was partly covered and partly open to the weather, there were trees in the aviary and for feeding the aviary was accessed from a passageway at the back, where fibre cement heating panels for each aviary, reduce the chill on cold winter’s nights. 182 BARNICOAT - WHITE-THROATED MAGPIE- JAY The first year the pairs seemed to be trying to dominate each other and no nesting took place. So, for the following summer the two pairs were split up and housed in separate, but similar aviaries, in which both pairs built nests of sticks in shallow wicker baskets 20cm (approx. 8 in) in diameter. They only chose baskets fixed up in the uncovered parts of the aviary flights and avoided those placed under cover. The first pair produced four eggs, but the female seemed restless and the incubation was unsatisfactory and none of the eggs hatched. The second pair had a clutch of five eggs, incubated well and hatched five chicks. A sudden cold snap one night led to the death of four them, leaving only one alive, which had been in the middle of the cluster of young and had, therefore, to some extent been insulated by the others. The surviving chick eventually grew into a fine young female, that was left with the parents. Eelco Meyjes The White-throated Magpie-Jay is found from central Mexico to northern Costa Rica. There were more fortunate breeding results the following year. Five eggs were laid and all hatched. However, for some reason or other two of the chicks died and were carried from the nest and placed in the food bowl on the third and fifth days respectively. The remaining three survived with BARNICOAT - WHITE-THROATED MAGPIE-JAY 183 help from their older sister from the previous breeding season, who helped feed them and also helped guard the nest. Within a month of fledging, the nest was relined and a second clutch of four eggs was laid, from which three chicks hatched successfully. One of these was carried dead to the feeding bowl on the eighth day, but the other two fledged. This means there is now a colony of eight birds - the original pair and six of their offspring. They are a picture of health and are incessantly active, with graceful movements, and obviously enjoy life together in a single aviary. It would seem that the parents enjoy having their offspring close to them and educating them about the rearing process. Possibly flocks seen in the wild are built-up in this way. Eelco Meyjes The female has a slightly shorter tail, more extensive black by the ear-coverts, a narrower breast band and slightly duller upperparts. Perhaps to a great extent responsible for this significant breeding success is the feeding regimen. Available at all times is a bowl ofNutribird T16 (little orange pellets, which the magpie-jays carry all over the aviary and hide in odd places, and which they retrieve later when they fancy eating them); also a bowl of the proprietary insect pate made by the Belgian company Orlux. Twice a day fresh meat is provided, usually skinned and gutted day-old chicks, cut into 1cm (approx. Ain) cubes, bone and all, or newborn mice. It is felt that the former provide the best results. When the magpie-jays have a growing brood of young, the supply of meat is increased and is virtually available on demand. Also given every two hours is a supply of mealworms (the giant type as well as regular-sized ones) and 6mm- 1 Omm long imported 184 BARNICOAT - WHITE-THROATED MAGPIE-JAY crickets. During the winter months the magpie-jays receive an austerity diet, from which the protein is cut-out on alternative days. Very apparent to me was the delightful rapport that has developed between the magpie-jays and their owner, who visits them regularly twice a day - for the morning feed and towards evening - so as to spot any problems as soon as possible. They obviously recognise him and respond to his presence in a confiding manner. The first sign of their decision to commence nesting is when they start placing an odd stick or two on the feeding-table, as though to communicate their intention, and most chicks that have died have been carefully placed in the food bowl, as though to make the fact known. In general most softbills soon develop a close relationship with their attendant and show trust and confidence. Avicultural Society Vice President Fred Barnicoat is a retired schoolmaster who taught Latin. He lives in Johannesburg, South Africa and is of Cornish descent. He joined the Avicultural Society in 1958 and continues to keep, breed and show aviary birds. The White-throated Magpie-Jay was first bred in the UK a few years ago at Paultons Park in Hampshire. Geoff Masson told me that the pair hatched one youngster this year and they always planned to leave it with its parents, having read that these birds live in family groups. If they are successful again next year, they have the opportunity to enlarge the aviary by opening it up and combining it with the adjoining aviary and allowing the group to grow. They have also hand-reared two chicks which they hope to pair-up with birds bred by a friend on the Isle of Wight. Geoff has been in contact with a number of breeders of this species in the USA, who seem to hand-rear all their young because, they say, the parents kill them. If they tried harder they could prevent this, Geoff believes, by providing the birds with forms of stimulation, such as, for example, throwing a lot oflivefood into the aviary to make the birds, particularly the male, hunt for it. Another idea is to give them sunflower seeds, which they have to hold in the foot on a perch and hammer open with their beak to extract the kernel. -Ed. 185 MANAGEMENT OF THE CRESTED PIGEON Ocyphaps lophotes AT EXMOOR ZOO by Derek Gibson Identification The Crested Pigeon, which has long been a familiar bird in aviculture - it was first bred in the UK at London Zoo in 1849 (Coles, 1986) - is readily identifiable (see photos of female on pp. 186-187). Sexing Visually sexing adults is not an easy undertaking, the key may be the orbital ring, with that of the male being more pronounced than that of the female; the metallic wing speculum is not a reliable guide, as it seems to vary from individual to individual. DNA sexing is obviously a more reliable method and puts an end to wasted breeding seasons, during which supposed ‘pairs’ fail to breed. Juveniles are also difficult to sex visually. Alternative names The Crested Pigeon seems to have a few alternative names. These include: Crested Bronzewing, Crested Dove and Whistle-winged Pigeon, the last name because its rapid wing-beats produce a distinctive whistling sound which is produced by air passing over a modified primary feather in each wing, when it takes to the sky; and, Topknot Pigeon, which is the name more correctly used for Lopholaimus antarcticus, a very different looking Australian species. Subspecies Two subspecies are recognised: G. I lophotes of central and eastern Australia; and G. /. whitlocki found in central and northern Western Australia. The latter is said to have narrower black wing-bars and less white on the tip of the tail. Distribution and habitat Found over most of Australia, avoiding only the more moist habitats in the far north and the south-east comer of New South Wales. Inhabits lightly wooded grassland, usually in the vicinity of water, be it in a suburban park with a pond or in flocks and pairs at water troughs on the numerous inland ranches. Feeding In the wild it forages almost exclusively on the ground, eating a wide variety of seeds and even feeding on noxious weed such as Salvation Jane or Paterson’s Curse Echium plantagineum , a species native to Europe, which has become an invasive species in Australia. It is also known to take insects, 186 GIBSON - CRESTED PIGEON Female Crested Pigeon, such as an Australian Psyllid Glycaspis brimble combei , more commonly known as the Red Gum Lerp Psyllid. Status The IUCN considers the Crested Pigeon to be of lower risk/least concern. Breeding Breeding in the wild seems to take place at any time of the year. The nest consists of the usual flimsy platform of twigs hidden in a dense, thorny GIBSON - CRESTED PIGEON 187 Silting female. bush, ! m 5m (approx. 3ft- 16ft) above the ground (Gibbs et ah 2001). Two white eggs are laid and are incubated for 1 8-20 days. Newly-hatched squabs weigh on average 9.5g and are cared for by both sexes until they fledge at 16-24 days (Brown, 1995). Exmoor Zoo Here at Exmoor Zoo we had Crested Pigeons on display in mixed exhibits with other species in various aviaries of varying dimensions for five years, during which time we never succeeded in breeding a single Crested Pigeon. At that point, the decision was taken to get all six Crested Pigeons DNA 188 GIBSON - CRESTED PIGEON sexed, as a result of which we discovered that all six were males. We were able to exchange two for DNA sexed females at the beginning of 2008. At present we have on exhibition to the public two DNA sexed males living in an aviary measuring approximately 4.9m long x 2.9m wide x 3m high (roughly 16ft long x 9ft 3in wide x 9ft 9in high). The floor is covered to varying depths with sand. The aviary is heavily planted with Eucalyptus cinerea , Zebra Grass Miscanthus sinensis ‘Zebrinus’ and Elephant Grass Pennisetum purpureum , a Cabbage Tree Cordyline australis and various species of bamboo. The eucalyptus provides most of the perching, but we also use Beech Fagus sylvatica branches about 2cm-4cm (%in- 1 Yzin) in diameter. Other birds in this mixed exhibit include Red-billed Quelea Quelea quelea , Snowy-crowned Robin-Chat Cossypha niveicapilla and Crowned Plover Vanellus coronatus, which seems to be a good mix of species both for the public and for the birds. The other Crested Pigeons, two males and two females, all DNA sexed, are housed off-display. At first each pair was housed in an aviary measuring 3.7m long, x 1.2mwide x 3m high (approx. 12ft long x 4ft wide x 9ft 9in high). Each aviary had perches placed at opposite ends of the flight and 28cm long x 21cm wide x 12cm deep (approx. 1 lin long x 8!4in wide x 5in deep) nest baskets placed 30cm (approx. 1ft) below the roof at the back of each aviary. When the males came into breeding condition both continually drove their respective mates literally all day. Wing-clipping the males failed to produce a satisfactory outcome and eventually they had to be separated to prevent any further problems. In April 2008 we changed our management and housed both pairs together in an aviary 3.7m long x 2.7m wide x 3m high (approx. 12ft long x 9ft wide x 9ft 9in high), which they shared with a pair of Crested Guineafowl Guttera pucherani. The floor of the aviary is covered with pea gravel. Both species were fed a diet which we make-up ourselves (see Table 1) and receive two supplements, Avi-Mix and Abidec. The guineafowl got livefood, such as mealworms, once a day, and it was customary to see the Crested Pigeons on the ground trying to eat as many as they could before the less agile guineafowl came along and quickly ate what remained. Once again the aviary had perches at opposite ends to provide them with the maximum flying space. They were though placed 0.3m (about 1ft) below the roof in an attempt to stop the guineafowl using them. The guineafowl had their own perching arrangement in the centre of the aviary. This was only 0.5m (approx. 1 ft 8in) rising to 0.65m (just over 2ft) above the ground in the shape of a triangle made from Beech branches 10cm (4in) in diameter. The nest baskets from the pigeons’ previous aviaries were used again. Dried grass and leaves, thrown onto the aviary floor, were provided as nesting material. GIBSON • CRESTED PIGEON 189 The male Crested Pigeons began displaying to the females at the beginning of May. The male really puts a lot into his courtship display: his wonderful tail is fanned and raised in the air, his head is directed down towards the ground and, with his entire body swaying up and down, he emits a rhythmic whoop , whoop, whoop We were interested to observe that the behaviour of the most driven male seemed to be defused as a result of it sharing the aviary with a larger species, especially one as large and relatively clumsy as the Crested Guineafowl. The first egg was laid on July 19th, followed by the second egg on July 20th. Everything went well in the aviary while the female was incubating the eggs. The only slight concern was that the other female was occasionally spotted sitting in the nest basket, near the eggs though not actually on them, while the female whose eggs they were, was at the feeding station (all four birds have different coloured leg bands for ease of identification). The first squab hatched on August 1 8th quickly followed on August 1 9th by its sibling. During the rearing it was noted that three birds seemed to be actively involved, although only the mother was observed feeding the squabs. The other male continued to display to any bird which was on the same perch as him, for as long as it remained there. The two young Crested Pigeons grew very quickly and almost before we knew it they looked like miniature versions of their parents. By the time the young were 1 4 days old, the femal e was spending more time off the nest, seemingly to encourage the young to fledge, which they did. The first fledged on September 3rd, followed by the second the next day, although both returned to the nest most evenings. Straight away the males began in earnest to drive the females again and it was not long before the first female had laid again. Once more two eggs were laid. The first was laid on September 11th and the second on September 12th. At no time was aggression shown towards the two young pigeons by the adults, but the guineafowl were inquisitive and, on arriving at the zoo one morning, one of the young pigeons was found on the ground. Thankfully, no serious harm had come to it. It had though lost its crest, so we were left with a crestless Crested Pigeon! As a result, the guineafowl were removed and housed in another aviary. The two young were seen feeding themselves on September 29th. One of the second clutch of eggs began to hatch on September 30th but, unfortunately, the second egg failed to hatch and was found to contain a partially developed embryo. As soon as they were a little bit larger and able to withstand the rigours of aviary life, the two older squabs were moved to the on-display exhibit, so that visitors to the zoo could appreciate that they are rather beautiful birds. 190 GIBSON - CRESTED PIGEON Derek Gibson Day one.

E-mail :Exmoorzoo@ btconnect. com/Derek. r.gibson@btinternet. com 192 THE SOCIETY’S VISIT TO COLCHESTER ZOO by Philip Schofield I visited Colchester Zoo frequently as a child in the 1960s. Like most zoos of the time, it functioned as more of a consumer than a producer of wildlife, with a preponderance of imported, wild-caught stock. From those days, I remember particularly Tayra, Grison and Malabar Squirrels among the mammals, and that the birds included wing-clipped crowned pigeons sharing an open enclosure with cranes and waterfowl. The impression was that Lions, Leopards and Cheetahs (the zoo had relatively ‘handleable’ examples of all three) were the most valued exhibits. There were, however, lots of animals, many of them in comparatively small functional enclosures with little in the way of stimulation. How Colchester Zoo has changed since then! It still gives the impression of being very full of animals, with comparatively little visitor space between the enclosures. However, the latter are invariably spacious, imaginatively designed and beautifully planted, with the animals presented in as natural and attractive settings as possible. We visited the zoo on March 28th, before the summer season had really got under way and, although I did not see any of the arena presentations, I understand that in addition to the more conventional owls and raptors, crowned cranes and guineafowl also take part. I hope I will be forgiven for writing in a bird journal about the mammals of Colchester Zoo. They are so varied, well-kept and interesting, that I cannot omit them. Large areas are devoted to African species, including an area with zebras, ostriches, White Rhinoceroses, antelopes and crowned cranes, with a bachelor group of three male giraffes. The youngest of these is a pure-bred Rothschild’s Giraffe, and it is hoped to work with this subspecies in the future. In their own large and well laid out area is the zoo’s group of African Bush Elephants, the repeated breeding of which (some by artificial insemination) must me one of the zoo’s crowning achievements. Five were in evidence at the time of our visit, and we saw some of the training that is carried out daily. As with all the animals at Colchester, the aim of training is to facilitate handling and health checks without the need for chemical restraint. Training also provides behavioural enrichment for the animals. Most of the mammals seem to be clicker trained, as are some of the reptiles, such as Slender-snouted Crocodiles and the two female Komodo Dragons (a species that until recently was either a legend or a distant memory in UK zoos, depending on whether one was old enough to remember the pre-war ones at London Zoo). We saw two female elephants interacting with their SCHOFIELD - COLCHESTER ZOO 193 keepers in free contact. Protected contact, in which the trained animal responds to cues and is handled through a safety barrier, is employed with the third, a less even-tempered cow elephant and also with the magnificent breeding bull and the juvenile home-bred bull. Amongst the group of zebras is an elderly female zebra x donkey hybrid, with a sign on the enclosure suggesting that the breeding of hybrids is not appropriate in the modem conservation zoo and that this animal is a relic of past attitudes. When I visited the zoo, perhaps 10 years earlier, three 4Zedonks’ were on show with their donkey mother. They had been bred in the early days of Colchester Zoo, when the impression was that the zoo could afford only one zebra. They received star billing in the local press and were a considerable attraction. Zebra hybrids, with a horse or donkey, are more commonly known as zebroids; ‘Zedonk’ appears to be Colchester Zoo's unique contribution to the English language. Another relic of the same era is a magnificent male orang-utan named Rajang, now in late middle age but still an impressive animal, with the deep intelligent eyes of his kind. He too is a hybrid, from the days when Bornean and Sumatran orangs were not always correctly identified and even the most reputable zoos inadvertently produced such hybrids. Rajang is vasectomised to prevent a second hybrid generation and it is hoped that an appropriate female companion can be found for him. Meanwhile, he reigns in a solitary state in an enormous new building purpose-built for orangs. Other primates include groups of Gelada Baboons, Squirrel Monkeys and Mandrills. Chimpanzees, including the chocolate mutation (originating perhaps from Twy cross Zoo!), occupy their own large and well-appointed complex. Other hoofstock housed elsewhere in the zoo, include the tiny Malayan Chevrotain and the Philippine Spotted Deer. A captive population of the latter, which is becoming increasingly rare in the wild, is fast becoming established in the UK. For those interested in zoo history, there is a good photograph of this deer (the type specimen photographed in 1870), in John Edwards’s London Zoo from Old Photographs ( 1 996). Young were reared at the zoo in succeeding years, but the species does not appear to have become established there. Spotted Hyenas used to be a feature of the collection at Colchester and, after the rest of the group had gone, I was introduced (through 2m (5cm) weldmesh) to the surviving elderly female named Mbembe, a charming and friendly animal. The collection also includes a young pair of Striped Hyenas. A young pair of Fennec Foxes have reared young and are likely to make further contributions to the UK population of this enchanting creature. Sand Cats were also on view at the time of my previous visit, but are no 194 SCHOFIELD - COLCHESTER ZOO longer represented in the Colchester collection. These two species, both very small and sandy coloured and with large ears, always seem to me to be canine and feline versions of the same model. Other cat species represented in the collection include Amur Leopard, Tiger and Margay. Turning to the birds: apart from a handsome pair of Egyptian Geese, waterfowl are conspicuous by their absence. The only other geese are what are apparently feral Canada Geese. I initially assumed that the Egyptian Geese were also free-flying birds, but they turned out to be pinioned. Although at large on the zoo lakes when we saw them, I wonder if they were fugitives from the nearby mixed African area. This area is overlooked by a tall aviary housing African vultures, some of which, such as Ruppell’s Griffon Vulture, have bred. Inside the African Pavilion, a breeding colony of Rufous-necked or Village Weavers was very active, with the birds displaying, quarrelling and working on their nests, above a group of Leopard Tortoises with whom they share the enclosure. Three male and one female Dalmatian Pelicans living at liberty on a lake and looking in good condition have not so far bred. This could change if the dietary adjustments suggested by a pelican-keeping member of our party are adopted. Most pelicans inhabit freshwater, but in UK zoos are fed on sea fish. Whereas in European zoos, situated further from the sea, they are more likely to be fed freshwater fish as a matter of convenience and, as a result, European zoos are more successful at breeding pelicans than UK zoos. We did not see the flock of 15 Chilean Flamingos, as the birds were still in their winter quarters. Consistent success is achieved at Colchester Zoo breeding Cattle Egrets, Humboldt Penguins and Hammerkops; five of the last named were reared in 2008. When the zoo opened in 1 963, among the first birds were Andean Condors and this species continues to be represented in the collection, at present by two females. An old male, perhaps one of the original birds, had died recently, apparently from lead poisoning. The collection also includes a pair of King Vultures. Also on view are Painted Storks (the Asian version of the African Yellow-billed Stork), which I do not recall seeing elsewhere. Among other birds on view are a fine pair of Red-billed Blue Magpies, surely one of the finest birds for public as well as private collections, that one can only hope will receive the attention needed to firmly establish a self-sustaining captive population. Colchester also has Stanley (Blue or Paradise) Cranes and East African Crowned Cranes. The latter have bred repeatedly and some of the young have been retained and trained as demonstration birds. We also saw Southern Ground Hombills and Asian Black Hombills, both viewed through glass, that is a feature of many of the zoo’s enclosures. It was an enjoyable day out to this major conservation-oriented zoo for the 55 members and their guests who travelled to Colchester in Essex. The SCHOFIELD - COLCHESTER ZOO 195 President’s Garden Parties apart, it was the best attended social meeting for many years and many, myself included, were left with the impression that we could have profitably spent two or three days there, to have done justice to all there was to see. I will certainly be going back again. Our Chairman Christopher Marler thanked Managing Director Dominic Tropeano for allowing us to hold our meeting at the zoo and for the wonderful hospitality we received and, in appreciation, made him an Honorary Member of the Avicultural Society. * * * PREFERRED NESTING MATERIALS One of our members is currently studying for a degree in zoo management and as part of the third year of his study is investigating whether Zebra Finches Taeniopygia guttata prefer natural or synthetic nesting materials. If you have any information which may be relevant, you are asked to contact Luke Forster by e-mail: lukeforster@hotmail.com * * * LAUGHINGTHRUSH CENSUS On behalf of the Avicultural Society’s Special Interest Groups, Andrew Owen, Curator of Birds at Chester Zoo, and Ian Edmans, Assistant Curator of Birds at Waddesdon Manor, are undertaking a census of captive-bred laughingthrash.es in the UK. There are currently 459 laughingthrushes known to be kept in the UK. Several of the 23 species being kept appear to be increasing in numbers, but others are represented by only one or 'two individuals. All keepers of laughingthrushes are asked to complete a questionaire, copies of which are available from Ian (see address below) or can be downloaded at: www.waddesdon.org.uk/aviary/aviary_publications.html Completed forms should be returned to Ian at: Waddesdon Manor Aviary, Waddesdon, Nr. Aylesbury, Buckinghamshire HP! 8 OJH. For more information about the laughingthrash census you can contact Ian at: Ian. Edmans@nationaltrast.org.uk The results of the census will be published in the Avicultural Magazine. 196 BOOK REVIEWS A SOUTH AMERICAN ODYSSEY For those of you who think that Rosemary Low only writes books about parrots - think again. Although weighted towards parrots, Rosemary’s latest book - Go West for Parrots! - is a fascinating insight into Rosemary’s travels over the past 30 years and the vast array of species and people that she has encountered. It is as much a travel log as it is a bird book and as such will be equally treasured by the traveller as it will be by the naturalist. With its stunning cover shot of Hyacinth Macaws flying over the Pantanal to its charming hand-drawn maps, this book is one which you will find difficult to put down. Rosemary has surpassed herself with the simple but highly effective layout of the book; each chapter covers a particular South American country or island group, and each country has an insert panel within the chapter, with details of interesting and sometimes little known facts about the area. Each chapter concludes with a list of species mentioned in the text, together with their scientific names, and a list of the threatened bird species in each threat category. Even though many of Rosemary’s acounts are of trips taken several years ago, each chapter is neatly rounded off with an update, providing details of the latest conservation measures being taken in the area, the current status of the birds, if it has changed, and, even in some cases, updates on the characters that she met. The book is illustrated with numerous photographs which really bring the text to life; these vary from images of the swamp men in Trinidad to Bolivian market scenes and the tranquillity of the Argentinian lakes; and, of course, a wealth of images of birds and other animals. If I had one criticism of the book, and it is a minor one, it would be that all the photographs are in black and white - it is such a shame that some of these stunning shots could not be reproduced in colour. In typical Rosemary style, this book is packed with well-written descriptions of wildlife, habitat and the amazing and often humbling characters that she has encountered on her travels. Whether you read it from cover to cover or just dip in to find out more about your next holiday destination, you will not be disappointed. This book deserves a much wider audience than just the avicultural and natural history market. When you buy a copy, why not buy a second copy and give it to a friend who knows nothing about birds, I guarantee that they will enjoy it and, if it does not awaken the dormant naturalist and conservationist within them, I will be truly surprised.

David Woolcock DISCOVERING NATURE IN BRITAIN AND NORTHERN IRELAND RSPB Where to Discover Nature in Britain and Northern Ireland is a new guide to RSPB (Royal Society for the Protection of Birds) reserves, with two to four pages on each. It is full of excellent colour photos, giving a good impression of the different habitats as well as examples of the birds, invertebrates and mammals which may be present on each reserve. Details include seasonal variations, facilities, what to look out for and occasional snippets of additional information about species present. The maps of the reserves are clear and informative, although an indication of scale would be helpful. The main problem I found with this book is the layout, which is by country and region, with no mention of counties and only one map on the inside front cover. It would be more useful if a map of each area was included, or if the reserve details included the county and nearest large town. Postcodes and grid references are given but these are useful only if you have maps/the internet immediately to hand. The title of the book is slightly misleading due to the clustering of RSPB reserves in certain areas. Thus the book does not describe many of the best places to discover nature in areas such as ‘the midlands5 (covering numerous counties) which has only five RSPB reserves. Conversely Scotland has 43 reserves and almost 100 pages describing them. Overall this is an attractive book that gives a comprehensive overview of RSPB reserves.

Shirley Ellis 198 LATEST FBF BREEDING REGISTER The latest Foreign Bird Federation (FBF) Breeding Register, which covers the period 2005-2008, reveals that a total of 16,679 birds of 522 species were recorded as having been bred in the UK in 2008. Although the total was higher than those for any of the preceding three years, there are no 2008 breeding records for a significant number of species and some others were bred in fewer numbers than one might expect - or at least that is what the records show. On the plus side, the number of Crested Wood Partridges Rollulus rouloul being bred each year seems to be rising, with an all-time high of 79 being bred in 2008. Twenty-six Chinese Bamboo Partridges Bambusicola thoracicus were bred, 14 Madagascar Partridges Margaroperdix madagascarensis and 15 Black Francolins Francolinus francolinus . One suspects that many more pheasants were bred than the records show. The Congo Peafowl Afropavo congensis , having last been bred in the UK in 2004, seems in danger of disappearing from the register. Here again, as always, a long list of waterfowl were bred, but not in the numbers one might expect, at least not according to the records; and, it appears, that neither the Caribbean Flamingo Phoenicopterus ruber or Greater Flamingo P. roseus were bred in 2008. Pleasingly, five Boat-billed Herons Cochlearius cochlearius are listed as having been bred. There are no records of the Corncrake Crex crex having been bred since 2004 or of the Socorro Dove Zenaida graysoni having been bred in 2008. This led me to suspect that some collections had not submitted their results and, upon checking, I was disappointed to discover that London and Whipsnade Zoos, Paignton, Edinburgh and the Wildfowl & Wetlands Trust are all missing from the list of contributors. Amongst the many pigeons and doves recorded as have been bred in 2008, were 10 Eared Doves Z. auriculata, 18 Luzon Bleeding-Hearts Gallicolumba luzonica , four Nicobar Pigeons Caloenas nicobarica and five Bruce’s Green Pigeons Treron waalia; three crowned pigeons Goura spp. were bred. Two hundred and twenty-one Grey Parrots Psittacus e. erithacus are listed as having been bred in 2008, plus 11 P e. timneh . Just two Blue-throated Macaws Ara glaueogularis are listed and four Military Macaws A militaris , as well as four Blue-headed Primolius couloni and five Yellow-collared P. auricollis. It is noticeable that several species of parrot have not been recorded as having been bred since 2004 or earlier. Turacos generally continued to do well: 19 White-cheeked Turacos Taurco leucotis were bred, 17 Fischer’s Turacos T. fischeri , 14 Red-crested T. erythrolophus and 1 1 Violet Turacos Musophaga violacea ; others bred FBF BREEDING REGISTER 199 included two Ross’s M. rossae, two White-crested I leucolophus and four Purple-crested 7 porphyreo lopkus . I am pleased to see that the Guira Cuckoo Guira guira was bred again in 2008. The Laughing Kookaburra Dacelo novaeguineae and White-collared Kingfisher Todiramphus chloris were bred, but not the Blue-winged Kookaburra D. leachii. Five Red-billed Hombills Tockus erythrorhynchus and five Von der Decken’s T. deckeni were bred, plus a Wrinkled Hombill Aceros corrugatus and a Writhed Hombill A. leucocephalus . A total of 45 Spot-flanked Barbets Tricholaema lacrymosa were bred between 2006-2008 and seven Spangled Cotingas Cotinga cayana were reared - one in 2008 and two in each of the preceding three years. Eleven Blue-crowned Laughingthrushes Dryonastes courtoisi were bred in 2008 and six Sumatran Black-and-white Laughingthrushes G. bicolor . A remarkable 7 1 Pekin Robins Leiothrix lutea were bred, 64 Chestnut-backed Thrushes Zoothera dohertyi and 1 7 Snowy-crowned Robin-Chats Cossypha niveicapilla (three fewer than the previous year) but, disappointingly, only six White-rumped Shamas Copsychus malabaricus were recorded as having been bred in 2008 and no Magpie Robins C. saularis. Probably more small seedeaters (waxbills, grassfinches and munias) than ever before are now being bred. The 2008 figures, for example, include 63 1 Cut-throat Finches Amadina fasciata , 23 1 Blue-capped Waxbills Uraeginthus cyanocephala , 122 Red-cheeked Cordon Bleus U. bengalus, 138 Golden¬ breasted Waxbills Amandava subflava ( Sporaeginthus subflavus ) and a large number of Australian species, with the Gouldian Erythrura gouldiae , of which 1,472 are listed as having been bred in 2008, way out in front of all of the others. Ninety-four Red Siskins Carduelis cucullata are listed as having been bred and 91 Mexican House Finches Carpodacus mexicanus. Eighty-four Cuban Finches or Grassquits Tiaris canorus were bred, an increase on the number bred in each of the preceding three years. One further breeding I cannot resist commenting on, is the breeding of seven Scarlet Tanagers Piranga olivacea - it is a species I cannot recall ever having encountered in aviculture - and I would like to know more about this breeding. The register provides a fascinating snapshot of the state of UK aviculture. It is interesting to see which species are thriving (i.e. breeding well) and which are not and are likely, therefore, as a result of the EU ban on bird imports, to eventually die out - perhaps never again to be seen in this country. Copies of the register for 2005-2008 are now available price £5 (post free). Cheques should be made payable to the Foreign Bird Federation and sent to the FBF Breeding Registrar: Reuben B. Girling, 1 1 Deramore Drive, Badger Hill, York YO10 5HW. Malcolm Ellis 200 NEWS & VIEWS DEVELOPMENTS AT LORO PARQUE Loro Parque announced in September that a further two Pesquet’s Parrots Psittrichas fulgidus had hatched and were growing up alongside their two earlier siblings. A Thick-billed Parrot Rhynchopsitta pachyrhyncha had also hatched, after the pair had broken the first egg. The second egg was removed from the nest and artificially incubated and a third egg was left with the female to incubate. As part of the international breeding programme, two adult female Lear’s Macaws Anodorhynchus leari arrived from Busch Gardens, Tampa, Florida. The two females were hatched there in the 1 980s, but because it had not been possible to find mates for them, it was decided to transfer them to the Loro Parque Fundacion (LPF) and at the same time transfer their ownership to the Brazilian Government. They were brought from the USA to Tenerife by the LPF President Wolfgang Kiessling. It is planned to pair them with two young males bred by the Loro Parque Fundacion, which now holds 17 Lear’s Macaws. An enormous, new, free-flight aviary, named Katandra Treetops - katandra in the Australian aboriginal language meaning “song of the birds” - has recently been opened in the parque. It houses various species of lories and lorikeets, cockatoos, kookaburras, crowned pigeons, fruit doves, Golden Pheasants Chrysolophus pictus, Mandarin Ducks Aix galericulata, egrets and many other birds. Waterfalls flow into a lake, surrounded by lush tropical vegetation, and there is a suspension bridge and walkways from which visitors can watch the birds. * * * CHANGES AT TWYCROSS Ben Potterton, Zoo Operations Manager at Twycross Zoo in Warwickshire, here in the UK, reports that the bird department has had an interesting past nine months, following a dramatic change in the department’s management, which resulted in an immediate improvement in breeding results. Macaroni Penguin Eudyptes chrysolophus , Humboldt Penguin Spheniscus humboldti, Cattle Egret Bubulcus ibis , Striated Caracara Phalcoboenus australis , Blue-winged Goose Cyanochen cyanoptera , Crested Wood Partridge Rollulus rouloul , Black-winged Ground Dove Metriopelia melanoptera and Boobook Owl Ninox b. boobook all bred and some of the parrots and Chilean Flamingos Phoenicopterus chilensis showed encouraging signs that they may breed in the near future. NEWS & VIEWS 201 A new collection plan was implemented early in 2009 and as a result several new species were added to the collection, these include Red Turtle Dove Streptopelia tranquebarica, Madagascar Turtle Dove S. picturata , Bar-shouldered Dove Geopelia humeral is, Temminck’s Tragopan Tragopan temminckii , Mountain Bamboo Partridge Bambusicola fytchii , Boat-billed Heron Cochlearius cochlearius and African Grey Hombill Tockus nasutus. These have been introduced into the old block of aviaries at the back of the Tropical House. Green Imperial Pigeon Ducula aenea , Little Pied Cormorant Phalacmcorax melanoleucos, Purple Heron Ardea purpurea , Black-crowned Night Heron Nycticorax nycticorax and Striated Heron Buteroides striata have been added to the birds in the Long-House Aviary and, Nyasa Lovebird Agapornis lilianae and European Roller Coracias gar ruins, are housed in off-show breeding aviaries. Southern Cassowary Casuarius casuarius are back in the collection after a short break and Raven Corvus corax , African Pied Crow C. albus and Silvery-cheeked Hombill Ceratogymna (. Bycanistes ) brevis have also been added to the collection. There have been a number of other new developments at the zoo during 2009. These include a new pet area which has an Australian walk-through aviary, that includes a prolific flock of Gouldian Finches Erythrura gouldiae. A new Himalaya building is due to open in spring 2010, one of the main attractions of which will be a large exhibit housing waterbirds. Some of these, including Little Grebe Tachybaptus ruficollis , Ringed Plover Charadrius hiaticula and Little Bittern Ixobrychus minutus , have already arrived and waterfowl, terns and other waders are due to arrive in the coming months. * * * BIRDLIFE APPEAL In Its latest letter appealing for donations to help fund its work trying to save threatened species, BirdLife IntemationaTs Chief Executive Dr Marco Lambertini writes that 1 ,227 species are on the 2009 IUCN Red List of birds under threat of extinction - that is over 12% of all bird species. With its partners it is working hard to control the use of the veterinary drag diclofenac which is such a potent threat to vulture populations in Asia and Africa. It is also working to protect remnant forests on Sao Tome, the Comoro Islands, Sangihe, Indonesia (home of the Red and -blue Lory Eos his trio and Sangihe Hanging Parrot Loriculus catamene ) and Brazil’s remaining Atlantic forest. Other measures include protecting and managing tropical forest in important bird areas in Indonesia, Colombia, Ecuador, Peru and Mexico. An Action Plan is being implemented to save the Spoon¬ billed Sandpiper Eurynorhynchus pygmeus , the population of which has 202 NEWS & VIEWS declined by more than 80% in the past 30 years, leaving just 400 remaining breeding pairs. Among its recent successes is the downlisting of Gurney’s Pitta Pitta gurney i from Critically Endangered to a lower threat category. This ‘jewel of the forest’ has benefited from improved protection and forest management, resulting in fewer chicks being lost to predators such as the Dog-nosed Cat Snake Boiga cynodon, as well as an increase in the number of earthworms, which account for three-quarters of the pitta’s diet. Other species similarly downlisted include the Gorgeted Wood-Quail Odontophorus strophium, Marquesas Imperial Pigeon Ducula galeata and Somali Thrush Turdus lidoviciae. To learn more about BirdLife International and its work you can visit its Website: www.birdlife.org or E-mail: birdlife@birdlife.org * * * FIRST SUCCESS FOR CAPTIVE BREEDING PROGRAMME The Institute for Research and Nature Conservation (Instituto de Pesquisa e Conservaqao da Natureza - Ideia Ambiental) of Curitiba, Brazil is working to conserve the Red-browed Amazon Amazona rhodocorytha in the wild, where as few as 845 birds are estimated to survive in the Atlantic forest of eastern Brazil; and, as an insurance policy, in 2006 initiated a parallel project to establish a captive breeding programme in Brazil. With financial support from the Loro Parque Fundacion (LPF) and the American Federation of Aviculture (AFA), a breeding centre was built on land owned by another of its partners, Curitiba City Zoo (Zoologico Municipal de Curitiba). The breeding centre will, it is hoped, establish a genetically viable captive breeding population of this species in Brazil, exchange information with other breeders, and may eventually be used to release captive-bred birds into the wild to boost the declining population. The project is run by Louri Klernann Jr of Ideia Ambiental and benefits from the advice of Pedro Scherer-Neto of the Curitiba Natural History Museum (Museu de Historia Natural Capao da Imbuia). The captive breeding programme began with 2 1 birds, confiscated by the Brazilian authorities and deposited with the centre by IB AMA (Brazilian Institute of Environment and Natural Resources). Following quarantine the birds were sexed and placed together in a large aviary to enable them to choose their own mates. At least seven pairs were established, which were transferred to breeding aviaries. It took two breeding seasons for all of the birds to reach maturity and feel comfortable in their new surroundings. Now, the first pair has nested and was recently rearing three healthy chicks. The other pairs were being closely observed in the hope that they too might be about to breed. NEWS & VIEWS 203 END OF SEASON REPORT Birds bred at Chester Zoo during the 2009 breeding season included two Socorro Doves Zenalda graysoni and two Montserrat Orioles Icterus oberi . It was the first time either of these species have bred there. Five Ecuadorian or Lilacine Amazons Arnazona autumnalis lilacina were bred, three of which were hand-reared. Currently it is the only collection in the UK breeding the Fairy Bluebird Irena puella, the chicks of which are hand-reared. Two pairs of Tawny Frogmouths Podargus strigoides produced five young (this species also bred at London Zoo). Caribbean Flamingos Phoenicopterus ruber and Chilean Flamingos P chilensis also had a good breeding season. Breeding programmes are being planned for the Sumatran Black-and-white Laughingthrash Garrulax bicolor and Red Bird- of- Paradise Paradisaea rubra , the zoo having recently acquired three females of the latter, which it hopes to pair with its three existing males. The zoo’s new walk-through aviary, called the Tsavo National Park Bird Safari, was officially opened recently. It houses birds living in Kenya’s Tsavo National Park, where Chester Zoo supports a number of key conservation projects. It is hoped the aviary will eventually house up to 15 different species, these include Hamerkop Scopus umbretta , Hottentot Teal Anas hottentota , Von der Decken’s Hombill Tockus deckeni , Lilac-breasted Roller Coracias caudatus , Superb Starling Lamprotornis superbus and weavers Ploceus spp. Bird staff continue to work on conservation projects abroad, notably with the Mauritius Fody Foudia rubra and Mauritius Olive White- eye Zosterops chloronothos on the Indian Ocean island of Mauritius and the nearby He aux Aigrettes. The zoo also continues to support Prof. He Fen-qi’s work with the Blue-crowned Laughingthrash Dryonastes courtoisi in China. * * * WINTER WEAVERS Here in Cornwall, down in the far south-west, we had a relatively mild (but very wet) late autumn (fall) and early winter, nevertheless it came as a surprise to learn that Village Weavers Ploceus cucullatus were still nesting outdoors at Paradise Park, Hayle, at the beginning of December. On December 3rd, Curator David Woolcock told me that in their entrance aviary, protected only by a piece of clear plastic sheeting to prevent the rain causing a problem, Village Weavers had four nests, three of which contained chicks and, fresh eggshell on the floor that morning, suggested that the fourth nest might also contain chicks. Already, more than 20 young had been bred in 2009. David added, that in December the biggest problem is keeping up a supply of long grass for nest building. 204 NEWS & VIEWS ASTONISHING SUCCESS In their Christmas card featuring “Birds of Texas: Big Bend Country”, Josef and Natalie Lindholm confirmed that since 2007, 1 9 Andean Cocks-of- the-Rock Rupicola peruvianas have been hatched at Dallas World Aquarium, of which 14 are still alive. Josef and Natalie went on to reveal that over 200 toucans, toucanets and araqaris of 14 taxa were hatched at Dallas World Aquarium during 2009, of which at least 170 survived. Another probable first captive breeding, to go with the breeding of the Many-banded Ara^ari Pteroglossus pluricinctus and Fiery-billed Araqari P. frantzii (mentioned in the previous issue), was the breeding of the (Panamanian) Blue-throated Toucanet Aulacorhynchus caeruleogularis (formerly the Blue-throated Emerald Toucanet A prasinus caeruleogularis). There are now 29 taxa of toucans, toucanets and ara^aris represented in the aquarium’s bird collection. New species and subspecies added during the year included Blue-banded Toucanets A. coeruleicinctus and its first Lettered Ara9aris P inscriptus and Black-throated Toucanets A. atrogularis (formerly the Black-throated Emerald Toucanet (A. p. atrogularis). Homed Guans Oreophasis derbianus , Wattled Guans Aburria aburri , Helmeted Curassows Pauxi pauxi and Homed Curassows P unicornis , as well as Nocturnal Curassows Nothocrax urumutum and Blue-billed Curassows Crax alberti , have arrived from Dr Estudillo. * * * NEWLY DISCOVERED POPULATION OF RARE PARROTS A new population of the Critically Endangered Yellow-eared Parrot Ognorhynchus icterotis , consisting of a breeding colony of some 100-120 birds, has been discovered on the eastern slopes of the Andes in Colombia. The birds nest and feed not in Wax Palms Ceroxylon quindiverse, but instead nest in the smaller Andean Royal Palms Dictyocaryum lamarckianum , which grow below 2,000m (approx. 6,500ft) above sea level. A team of field workers belonging to Fundacion ProAves has evaluated the new location and believe the birds may be a relict Eastern Cordillera population that has managed to survive by adapting to different habitat. Because so few Wax Palms survive in the highlands (where they are cut down for Palm Sunday celebrations), the Yellow-eared Parrots are coming down to 1 ,200m- 1 ,500m (approx. 4,000ft-5,000ft) to nest in the Andean Royal Palms. The area is very steep and relatively heavily forested, although gradually being cleared and, therefore, at some risk. Each day the parrots fly up to less accessible higher elevations. ProAves has a good working relationship with local landowners and will continue to monitor the population and plan the best way to conserve the site. 205 Contributors to Volume 115 - 2009 Ackroyd, Nicholas The parent-rearing of Hooded Pitta chicks Pitta sordida mulleri in a mixed species walk-through exhibit at ZSL London Zoo................. 27 Bamicoat, F.

Jo wants to find out where the cassowaries in Europe originated from and what is their genetic make-up. The team plans to approach all the zoos in Europe and ask them to provide DNA samples, so that an attempt can be made to trace the origin of their birds. It is suggested that there could be up to eight distinct forms of the Southern Cassowary Casuarius casuarius. These may be subspecies or could even be distinct species - nobody is quite sure. In their 1980 checklist, Howard and Moore recognised three species of cassowary, the Double-wattled C. casuarius , Dwarf C. bennetti and One-wattled C. unappendiculatus, with several subspecies listed for each of them. In his 2007 checklist, Clements (citing as his reference source Handbook of the Birds of the World Vol.l) recognised the same three species, known now as the Southern, Dwarf and Northern Cassowaries, but listed no subspecies. For more than 30 years cassowaries have been kept at Paignton Zoo, during which time a total of 1 7 have been bred. Currently it has five Southern Cassowaries. Found in New Guinea, the Aru Islands and Queensland, north-eastern Australia, the Southern Cassowary is threatened by human encroachment, especially in Queensland, where as few as 1,500 may remain. Continuing loss of habitat for residential, agricultural and industrial development is contributing to the decline of this species in Queensland. Birds are injured or killed in collisions with vehicles and in dog attacks. * * * BIRD PARK FOR SALE Come and enjoy the clean green lifestyle New Zealand has to offer.
