THE BIRDS OF THE BRITISH ISLES AiND THEIR EGGS. Order ANSERIFORMES. Family AN AT I D.^. Geese, Swans, and Ducks. The Anatidcp, all swimming birds, have the three toes in front connected by membrane ; they are web-footed. Grey Lag-Goose. Anser anser (Linn.). The geese which occur in Britain fall into three natural divisions or groups, the first consisting of five species, known as the "grey geese." Of these the Grey Lag (Plate 2) is the only one that nests with us ; the others are winter visitors. A century and more ago the Grey Lag bred on moors and marshes in various parts of England ; now it nests only in the north of Scotland and some Hebridean islands. It breeds in northern Europe and Asia, and winters in the Mediterranean and southern Asia. Grey geese are exceedingly variable in size and plumage ; the assertion that any species may infallibly be identified by certain Series II. B 2 THE BIRDS OF THE BRITISH ISLES. characters is apt to mislead. Passing " skeins " of grey geese usually fly too high and fast for identification, and "gaggles " feeding or resting are too alert to permit close scrutiny. Even in the hand a bird, especially if immature, may puzzle an expert by its variation from type ; disputes over species, sub-species, and races are never ending. The typical characters of the Grey Lag are lavender-grey shoulders, lower back and rump, and flesh-coloured white- nailed bill and legs. The Bean-Goose, which approaches it in size, has a brown rump, its legs are pink, and its bill black and orange. From the White-fronted Goose, with orange, white- nailed bill and orange legs, it may be told by its pale shoulders and rump ; the Pink-footed has a dark rump, though its shoulders are blue and its legs pale and fleshy, but its bill is black and yellow and the terminal nail black. These characters look simple, but immaturity and individual variation have led to errors. The origin of the name is obscure. The New Oxford Dictionary supports the view of Prof. Skeat that it was the goose that lagged behind when others migrated, but Mr. Harting suggests that it is derived from the Old English lea, a field, and others have cited the Middle English lac^ a lake. An old sporting term for a flock of geese was a lag. The general habits of all grey geese are similar ; they are normally diurnal feeders, cropping grass and gleaning grain. When, however, the fields are disturbed by farmers or others, or on moonlight nights, they adapt themselves to circumstances, and after spending the day on the banks or tide-line, flight inland at dusk. On the coast the uncovered banks are their usual nocturnal haunts, and inland the gaggles sleep in some open country or quiet water ; at daybreak they go off to feed, flying in ordered lines or in chevron formation. If forced to remain in the estuar)- or on the shore during the day they are unsettled and restless, skeins repeatedly taking short flights to ■if 2 P/. 2. Grey Lag-Goose. Bean-Goose. B2. GREY LAG-GOOSE. 3 reconnoitre. Grain, grass, clover, and other vegetable substances are their regular food ; in many places they can find sufficient grass on the saltings without risking trips to the cultivated land. Migratory Grey Lags reach us from mid-September onwards, and remain until April or May. Certain localities attract the bird, which is more plentiful on the west than east coast ; even in the west and in Ireland it is local. The call in flight is loud and sharp, a deep sonorous ackh, ackh, almost exactly the note of the domestic goose, of which it is probably the most direct ancestor ; when the birds settle, the clonking clamour resembles that of other greys. During the breeding season the pair con- verse in familiar language, the contented undertones of the farm- yard. On land it walks with ease and dignity, without the waddle of the overfed domestic bird ; it swims lightly, and if threatened during the moult, when through the simultaneous loss of the flight feathers the bird is helpless, it dives with skill. In flight the slow, measured beats betoken strength, and the speed attained has astonished many an inexperienced sportsman. The nest is large, placed in thick heather, rushes, or other vegetation. Little or no lining is provided when, in mid-April, the four to six yellowish-white eggs are laid, but the goose con- stantly adds down until the eggs are concealed. The average size, according to the Rev. F. C. R. Jourdain, is 3*4 ins. by 2*3 ins. The sitting goose (Plate 3) is shy and nervous, turning her head from side to side, her neck feathers dividing in sinuous creases ; she is on the alert to sight or scent danger, as Miss E. L. Turner found when photographing the bird figured. The down-clad yellowish-brown and yellow goslings are usually hatched in May ; their under surface is at first a wonderlul golden yellow. The head and neck of the adult bird is light brown, the upper parts, greyish brown, darkest on the wings and scapulars ; the shoulders, lower back, and rump are blue-grey. The ashy- grey tail is tipped and bordered with white, and the upper and 4 THE BIRDS OF THE BRITISH ISLES. lower tail-coverts are pure white. The breast is suffused with brown, and the belly is dull white with a few dark blotches and bars. There are often some white feathers at the base of the bill. The sexes are alike and there is no marked seasonal change. The white-nailed bill and the legs are flesh-coloured, the irides dark brown. The immature bird is darker and lacks the spots and bars on the under parts and the white above the bill, whilst the bill is yellow or orange and the legs are piler. Mr. Abel Chapman found great variation in the colour of legs and bill in both old and young ; it ranged from almost white to yellow and, exceptionally, orange. The gander is the bigger bird, but the size varies greatly, and all measurements of this and other species must be treated as averages. Length, 30-34 ins. Wing, 18 ins. Tarsus, 3*3 ins. Bean-Goose. Anser fahalis Latham. The Bean-Goose (Plate 2) is a rather uncommon winter visitor to most parts of Great Britain and Ireland, though locally it is numerous. It breeds far north in Europe and Siberia, and occurs in winter throughout Europe and in many parts of Asia. Bean-geese with much yellow in the bill have been separated as A. arveiisis, but there is great variety in the soft parts of all grey geese. The back bill crossed by an orange band, and the orange legs serve to identify the typical Bean ; the legs of the Pink- foot, which has a somewhat similar bill, are flesh-coloured. The general colour, especially on the shoulders and rump, is darker than that of the Grey Lag ; on the wing its head and neck look very dark, darker even than the Pink-foot, and the white upper tail-covcrts show up against the brown rump. To my ears the call, honk^ honk, is softer and more bell-like than the note of the Pink-foot. The flight is strong and direct, the wing-beats slow ; on the water the bird looks large but rather WHITE-FRONTED GOOSE. 5 slender, and its weak bill long ; as in other greys, 'iihe feathers on the nape and back of the neck stand out in a mane. When the bird is feeding the neck is not curved as in the swans, but has a sharp kink or angle ; this is noticeable in any greys, when with neck stretched and beak open one bird attacks another in play or anger. Immigrant Beans arrive in September and October, and some linger until April or later. They share the field-feeding habit with the Grey Lag, and both near the coast and inland the bird is a hanger-on at the harvest. The upper parts of the mature bird are greyish brown, darker than in the Grey Lag, but the shoulders are sometimes grey, though never so blue. The pattern or barring on the wings and scapulars, due to the pale and often white edgings of the feathers contrasting with the brown, is more distinct than in the previous species. One March-killed male examined was almost as grey as a Grey Lag, but the rump was distinctly brown. The under parts are pale brown on the breast, passing to dirty white, often showing obscure bars. The bill is black at base and tip, including the nail, crossed by an orange or deep yellow band, the size and shape of which varies individu- ally. The legs are orange or pinkish yellow, the irides dark brown. There are sometimes white feathers at the base of the bill. The goose is smaller than the gander ; the young bird is darker except on the rufous-tinged neck. Length, 31-34 ins. Wing, 17*5-19 ins. Tarsus, 3 ins. White-fronted Goose. Anser albifrojis (Scop.). The White-fronted Goose (Plate 4) is a winter visitor, often numerous, especially on the west coast and in Ireland. Its northern breeding area extends from Greenland and Iceland to northern Siberia, including most Arctic islands ; in winter it reaches southern Europe, northern India, and north Africa. 6 THE BIRDS OF THE BRITISH ISLES. The North American bird, often described as a sub-species, winters so far south as the Gulf of Mexico. The White-fronted Goose, at any rate when mature, is easy to identify ; it is smaller than the Grey Lag and the white at the base of the bill is a broad and conspicuous band. The beak is orange with a white nail, distinguishing it from the Bean and Pink-foot, and the legs are darker than those of the Grey Lag ; the only species with which it can be confused is the smaller and darker Lesser White-fronted Goose. There are broad dark bars on the breast and belly, and the note, from which it gets its name of " Laughing Goose," is distinct, louder and harsher than the metallic cry of the Pink-foot. W^hen the two are flying together the White-fronted is easily picked out by its frontlet and dark flanks. Immature birds, however, have less white on the forehead, and in some, young females probably, there are no bars ; the nail maybe not white but brown, though never black. The habits are similar to those of other greys ; it feeds on grass and clover, but is perhaps more of a marsh than cornfield species, and may be seen in estuaries moving with the tide, flighting to the marshes and fields at high tide and returning with the ebb. It arrives and departs at the same seasons as other greys, and is not infrequent in inland marshes and river valleys ; the bird is most abundant in December and January. The plumage is ashy brown with pale edges to the feathers of the back, and the under parts are crossed by dark brown or black bars and blotches ; the flanks are dark brown, the under tail-coverts white. The legs and bill are orange, the nail white, the irides dark brown. Length, 27-28 ins. Wing, 16-17 ins. Tarsus, 2'6 ins. Lesser White-fronted Goose. Anser erythropus (Linn.). This small goose was added to the British list by Alfred Chapman, who shot one in September, 1886, near Holy Island. j^^ . '^.^ -J^ 2 PL 4. White-fronted Goose. Pink-footed Goose. B 6. PINK-FOOTED GOOSE. 7 Others have since been reported, but the exact status of the species is uncertain. The range of the bird is restricted ; it is known to breed in Lapland and Novaia Zemha and in eastern Siberia, and winters rather further north than the last species. It is smaller, darker, and has a shorter bill than the other, and sometimes has a greater extent of frontal white ; the validity of the species has, however, been questioned, and it might, with some reason, be treated as a small race of A. albifrons. Chapman's bird was immature ; the breast was "warm reddish brown " and the belly grey dappled with black. The bill was pink, the legs yellow-ochre. Length, 20-24 ins. Wing, 15-5 ins. Tarsus, 2*5 ins. Pink-footed Goose. Afiser brachyrhyncJms Baillon. The Pink-footed Goose (Plate 4), a winter visitor, is in many parts the best known of our grey geese ; though most numerous on the east coast it is locally abundant in the west, but only a straggler to Ireland. It breeds in Iceland and Spitzbergen and perhaps in other islands, and winters in western Europe. As the specific name implies, the bird may be recognised by its short bill, black at base and tip and with an intermediate pink rather than orange band, usually smaller than that on the bill of the Bean. The legs are flesh-coloured or pink. Although a brownish bird it looks very light in sunlight, this being partly due to the blue-grey shoulders and greyish back, darker than those of the Grey Lag. The Pink-foot is gregarious; the gaggles are frequently huge. The skeins fly in lines, V's, or double chevron formation ; the birds call constantly as they fly ; their metallic voices carry for great distances. The quality varies, some are harsh, others shrill and musical. When following the tide the birds alight on the uncovered banks and stand alert with necks uplifted. 8 TEIE BIRDS OF THE BRITISH ISLES. When satisfied that they are secure, they rest or preen their plumage, but when driven off by the tide immediately begin to call and rise with a mighty rush of wings and babel of voices. Many birds reach the west coast about the third week in September, but the skeins come in gradually and it is usually the end of October before the winter flocks are complete. Emigration begins in March, and most have left before the end of April. As soon as they arrive the birds visit the fields, gleaning in the stubbles in the early morning and at dusk, but when forced by circumstances to avoid the cultivated land they crop the grass on the saltings : they are always shy and nervous, and the approach of a man sends them off "honking" to the banks. The Pink-footed Goose was long confused with the much larger Bean, but in the majority of examples the colour of the bill is noticeably darker than the legs. Ridgway's "vinaceous pink " was the shade of the bill of most birds that I have examined. In one bird the pale pink legs were distinctly tinged with vermilion. The head and neck are seal brown, the upper parts greyish brown, darkest on the wings and scapulars, and with bars formed by the pale feather tips ; the rump is brown. The breast is brown, the belly suffused with grey shading to pure white. The irides are dark brown. The young bird is darker. Length, 27-28 ins. Wing, 16*5-1 7*5 ins. Tarsus, 2*8 ins. Snow-Goose. Chen hyperborcus (Pallas). As a winter visitor from the Arctic of eastern Asia and western America the Snow-Goose (Plate 10) has been reported so frequently as to claim a place in our avifauna, though it is always rare and uncertain. Two forms occur in America, the Lesser C. h. hypcrboreus being the western race, and the Greater Snow-Goose, C. h. nivalis (Forster), breeding in Green- SNOW -GOOSE. 9 land, yet it is curious that the latter, which migrates south along the Atlantic seaboard so far as Florida, has only once been known to visit us — an example obtained in Ireland in 1886. The smaller bird ranges south in winter to the western States and Mexico, and has been met with in various parts of Europe ; it is therefore probable, especially as Gatke knew the bird in Heligoland, that the autumnal movements of the species are westward and that our visitors do not reach us via Greenland. The Snow-Goose, white with black wings, is conspicuous and unlike any other wild goose ; its black flight feathers prevent confusion with the swans, and the only other large white bird that in any way resembles it is the Gannet, whose short neck, cigar-shaped body, and easy sailing flight are distinctive. No wildfowler would be misled, and though there are more reports of birds seen than obtained, records by such observers as Sir R. Payne-Gallwey, H. A. Macpherson, and Mr. G. Bolam leave no doubt in the mind. Furthermore, in severe winters, flocks have been observed in different parts practically at the same time. The bird has been seen or shot on both the east and west coasts of England and in Ireland. The flight is strong, and Macpherson noticed it as "leisurely " ; the voice is described as harsh. The visits have usually been during exceptionally hard weather, but a bird was seen in the Solway on August 22nd, 1S84. The adult bird is white with black primaries. The legs and bill are red, the latter with a whitish nail ; the irides are dark brown. The young bird is brownish grey, darkest on the upper surface ; its bill is almost black, and its legs plumbeous tinged with reddish yellow (Dresser). Length, 25-28 ins. Wing, 15-17 ins.

The Brents and Barnacles are collectively known as " black geese " to distinguish them from the " grey "' group. They are more maritime in their habits than the grain-eating greys and feed largely on Zostera and other marine plants. Two, if not three geographical races of Brent have been recorded as winter visitors to our islands, and the B.O.U. Committee, though rejecting the Black-bellied Pacific B. nigricans (Lawrence), with a complete or almost complete white collar, as having been recorded on insufficient evidence, retain the dark B. b. bertiicla and the Pale-breasted American B. b.glaiico- gaster (Brehm), which the editors of the " Hand-List" now consider as varieties, since, as shown by M. Alpheraky, they nest in the same area. The Brent (Plate 7) is, on the wing, a small dark goose, stumpy and almost duck-like. The small white patches on its neck, and the white tail-coverts and abdomen show con- spicuously in contrast with the black head and neck and general dusky plumage ; the white stern is specially notice- able, for the coverts above and below almost screen the dark tail. The bird is very gregarious ; huge packs visit the east coast and Ireland, and it is met with in smaller numbers all round our shores. October is the usual time of arrival, though a few come in September; Mr. Abel Chapman considers the 17th of the latter month exceptionally early for Northumberland, and says that the numbers are seldom large until after Christmas. In two consecutive years the first reached the Yorkshire coast on October 6th and September nth, but in the former case one bird only, some days before I saw others. Most leave in March or April, but stragglers may remain until May or even later. The Brent feeds by day, but it rarely leaves the shore, finding its vegetable, and occasionally /^^f^f^l* f^^l^ € ::^^ 2 /'/. 7. Brent Goose. Barnacle-Goose. B II. BARNACLE-GOOSE. II animal food — molluscs and worms — on or In the ooze of tidal estuaries. Naturally its movements are largely regulated by the tide, and it occasionally feeds in the dusk. The birds, in long lines, follow the receding water, their angled necks bent as they gobble the sea-grass, or are slowly driven back by the flood, still feeding ; in shallow water they swim and dip their heads to drag up the weed, or upend like ducks, their white sterns alone visible. The Brent walks gracefully, can run fast, and flies with considerable speed. A disturbed pack flies hither and thither, taking ordered formation only when travelling for a distance. The flight call is loud and metallic, a double note frequently repeated. At high tide the birds swim in the open, avoiding the shore, but return as soon as the banks are exposed. Adult Brents have the head, neck, upper breast, and back slate-black, a small white patch, in which black is often mingled, on either side of the neck. This patch varies in size, and occasionally meets in front, forming a more or less complete ring. The lower neck is slate-grey, the sides of the rump and upper tail-coverts white. In the dark-breasted form the under parts below the breast are slate-brown, showing distinct whitish bars on the flanks ; in the paler form the lower breast is brown and the rest white or suffused with grey. The bill and legs are almost black, the irides dark brown. Immature birds are browner, and the neck spot is hardly visible. Length, 22 ins. Wing, 135 ins. Tarsus, 2 ins. Barnacle-Goose. Branta kucopsis (Bechst.). The Barnacle-Goose (Plate 7) nests in Greenland, Spitz- bergen, and probably elsewhere in the Arctic, and in winter is common in northern European seas, and occasionally reaches the Mediterranean and Azores. It is more frequent in the Hebrides than the Brent, and is plentiful on the west coast of 12 THE BIRDS OF THE BRITISH ISLES. Scotland and the north of Ireland ; in the Solway it is less numerous than formerly, and though it used to visit the Cheshire Dee in some numbers it is now only a rare straggler. Its winter quarters are more northerly than those of the Brent. The Barnacle, though a marine feeder, is less strictly addicted to salt water than the Brent, for it will feed on marshes and cultivated land bordering bays and inlets. Larger and paler than the last species, its black crown and neck and white face are its noticeable features ; its under surface is greyish white. The first Barnacles arrive towards the end of September, but the bird is stldom numerous until late October ; they leave in March and April, but emigration is often delayed in the north. It is a nocturnal feeder, at any rate on the pastures ; during the day it rests on flats or marshes, but I have disturbed birds which were apparently feeding by day, and the flocks will visit the edge of the saltings to graze. Dr. Patten de- scribes the voice as low and " pl-easing to the ear," though it has been likened to a "coughing grunt," and a gaggle can raise a clanging clamour of sharp yelping cries. Not only is the bird easy on its feet, but it can run swiftly, scampering across the flats with outstretched neck after a companion in anger or play. The flight is powerful and often at a height ; indeed, it is likely that it is at times above the range of vision. When in April, 1913, eighteen birds were killed by lightning in the Solway, Mr. Portal records that none was seen or heard until their bodies crashed to the ground. The name is not derived from its food, though, like the Brent, it will eat molluscs and crustaceans, but from the ancient myth that the ship- barnacles gave birth to gee-e. The white face and forehead of the Barnacle is set off by its black cap and neck, and there is a black mark from the bill through the eye. The upper back and breast are black, the lower back and rump brown, but the upper parts generally are lavender-grey barred with black and white. The under parts CANADA GOOSE. I 3 are white, as are the sides of the rump and upper tail-coverts ; on the flanks are faint grey bars. The bill and legs are black, the irides dark brown. The blacks in the old bird are replaced by brown in the young, and the whites are suffused with buff and spotted ; the barring on the flanks is often more distinct. Length, 25 ins. Wing, 16 ins. Tarsus, 2'2 ins. Canada Goose. Branta canadensis (Linn.). The Canada Goose (Plate 5) is usually denied a place in the British avifauna on the ground that when it has been recorded it must have ** escaped from captivity or from ornamental waters.' The bird, which has several well-marked forms, is a native of North America, migrating so far south as the Gulf of Mexico. Our bird is referable to the large eastern race. Though there is no actual proof that the Canada Goose ever reaches us as a migrant, birds which have appeared in the Hebrides may have been truly wild. Yarrell included it as British because it has been known as an introduced species for more than two centuries. hideed it is, at any rate in certain areas, so firmly established as a free-living and not domestic bird, that its claim seems to be as sound as that of the Mute Swan, the reintroduced Capercaillie, the Little Owl, and the Pheasant. The Canada differs from the smaller Barnacle in the pattern and extent of the white on the face and the smaller amount of black on breast and neck. The upper parts are brown, not grey. In many parts of our islands the bird is merely a straggler, always treated with suspicion, but in East Anglia, Lancashire, and Cheshire, and a few other areas, it lives a wild life, nesting on the borders of broads, meres, or pools, and living gregariously during the greater part of the year. In Cheshire no one claims them, no one attempts to capture and mark them ; flocks of a score to two hundred birds wander from mere to mere. 14 THE BIRDS OF THE BRITISH ISLES. The nest, usually close to water, is a large structure of reeds or other waterside plants, thickly lined with down. I have found from four to seven eggs. The gander swims on guard, though often at a distance, but the clanging alarm of the goose will bring him at once ; then both will swim near the nest honking and extending their necks in sinuous curves, en- deavouring to terrify the intruder. The whitish eggs are usually laid early in April. The normal migratory instinct appears to have been lost, but the birds are wanderers during the winter, and the numbers to be met with in any particular haunt vary greatly. When the young are on the wing in July, the Cheshire birds, in flocks, flight nightly towards the hills, returning to the meres in the early morning, but whether the object is to roost on the reservoirs or to feed at night on the moors I have failed to discover. Normally the birds feed by day on the borders of the meres, cropping the grass, and they also visit cultivated fields. These passing flocks of " wild geese " are frequently noticed in the first half of July, but seldom later, though the birds move freely during autumn and winter. The note is a resounding ho)ik, honk^ sounded if the feeding birds are approached, and as they walk towards the safety of the water ; they take wing if followed. The face to behind the ear-coverts, and the chin and throat, are black, and the sides of the face are white, a marked cravat in contrast to the black neck. The upper parts are brown, pale feathtr-edgings forming bars ; the Hght brown flanks and belly are faintly barred. The legs and bill are black, the irides brown. Length, \z ins. Wing, 19*5 ins.

Half a dozen or so of the reported occurrences of the bird in England are supposed to be due to genuine migration, but others are either errors or may be due to wandering from private waters. The showy bird appears on mural paintings in Egypt. This goose is sociable and a vegetarian ; it has been shot when consorting with both Brents and Barnacles. The upper parts are black, and the sides of the face and neck and the breast are rich chestnut bordered with white. There is a large white patch at the base of the bill, separated from the cheeks by a black line which passes through the eye from the crown to the chin. The belly is black, the flanks and tail-coverts are white. The short bill, legs, and irides are dark brown. The immature bird has less rufous on the face. Length, 21 ins. Wing, I4'5 ins. Tarsus, 2 ins. Whooper Swan. Cyg?ms cygnus (Linn.). Three swans are on the British list, but two only, both winter visitors, can be counted as really wild. The Whooper, or Hooper (Plate 9), breeds in northern Europe and Asia and ill Iceland, and winters in Europe, central Asia, and occasionally north Africa. It is frequent in Scotland and occurs round our coasts, though much rarer in Ireland than the smaller Bewick's Swan. Size, when there is no chance for comparison, is insufficient as a means of identification in the field, and there is little difference between the Whooper and Mute. The best character is the beak. In the Mute this is black at the base, where there is also a prominent knob or tubercle ; the rest, except for a black line along the cutting edge, is orange ; the black reaches to the eye. In both Whooper and Bewick's the pattern is reversed and the lemon-yellow extends from the «ye to the nostril ; in the former, however, the patch is larger and l6 THE BIRDS OF THE BRITISH ISLES. more angular, a wedge passing forward into the black tip beyond and below the nostril. A curious optical illusion is caused by the pattern of the Whooper's bill ; when the bird is some distance away the black tip appears to overhang. The Whooper seldom arrives before November, for it is, as a rule, a severe weather visitor, the conditions in its northern haunts rather than those prevaiHng here regulating its appear- ance. Its stay depends largely upon its reception ; undisturbed birds sometimes linger until June. It is perhaps a more frequent visitor to inland waters than its smaller congener. I have watched it on meres when Mute Swans were present, but have not seen it consort wiih them, but on the Eden at Carlisle a single bird came for several years in succession, and finally brought a family or companions to swim and feed with the Corporation herd of Mutes. Mr. L. E. Hope records that the visitors arrived at varying dates from November to February, and the latest stay of the original bird was until May 8th ; when the numbers had risen to seven and eight the birds left in March and April. I saw these birds with the Mutes actually in the town at the end of December (Plate 6). On the water the shy bird carries its neck stiffly erect, its bill at right angles as it turns its head sharply from side to side ; its wings rest flat upon its back and are not arched as in the Mute. From behind the wings show like two smooth cushions ; the short pointed tail is carried horizontally. When the head is lowered to feed, the neck has a goose-like angle and not the graceful curve of the Mute. Like other swans the bird upends, submerging the head and fore parts, paddling slowly to hold itself in position ; its wing tips are slightly raised. The food, aquatic weeds, molluscs and other animals, is mostly obtained from the bottom. When the bird rises, head to wind, it flogs the water for some distance. Once under way it flies with great speed and power, its neck extended, the swish of its long wings producing a whistling sound quite distinct BEWICK'S SWAN. 1 7 from tte throb of the flying Mute. It is, I believe, from this and not its call that the bird gets its name, "Whistling Swan." The ordinary name is derived from the note, a distinctive character. The call is variously described as a " deep-toned whistle," a trumpet, bugle, or bass trombone sound ; surely it must vary. My own notes say — " a clanging wu-iick or luoo-iick, the ending sharply rising." On its breeding ground in Iceland Mr. Jourdain heard a nasal, goose-like cry of alarm, and "a low but musical song of about seven distinct notes." All the swans are white when mature ; their bills vary as described above. The legs are blackish, the irides brown. The male is the larger bird. The young is pale brown, palest beneath ; the bill is flesh-coloured ; the legs at first are fleshy, but gradually darken. Length, 60 ins. Wing, 25 ins. Tarsus, 4'3 ins. Bewick's Swan. Cygnus hewicki Yarrell. Bewick's Swan (Plate 9) breeds further north in Arctic Europe and Asia than the Whooper, and in winter, though it is found in various parts of the two continents, its range is more northerly. Tt is a winter visitor to our islands, most numerous in Scotland and the north and west of Ireland. Although much smaller than the Whooper, the shape and size of the yellow patch on the basal portion of the short bill of Bewick's Swan is the best mark for identification. This patch is somewhat rounded in front and does not extend so far as the nostril. The colour of the patch is variously described as yellow, deep yellow, lemon-yellow, and orange in both this species and the Whooper, but in living examples that I have seen, usually, at any rate, has been lemon-yellow. Possibly these birds were young, for the shade certainly deepens with age, but I suspect that in some cases the writers have been misled by the dark colour of a dry skin. One distinction between the two wild swans, not always clearly shown in Series II. C l8 THE BIRDS OF THE BRITISH ISLES. fij^uies and seldom mentioned, is that there is one patch in the Whooper and two in Bewick's ; that is to say, the black on the bill of the Whooper only reaches part way up the culmen, whereas in this bird it extends to the forehead. This black line bordered on either side by yellow is very noticeable when the bird faces the observer. In the Whooper a band of colour crosses the base of the bill. In general habits, food, flight, and appearance Bewick's resembles the larger bird, with which it was long confused, but on the average its visits are shorter. There are records of its arrival in October, and Dr. Eagle Clarke gives November as its usual month for Scotland, but as a rule it is in December, January, and February that we see it ; it seldom remains until March. It is more gregarious than the Whooper ; herds of two or three hundred are not unusual, and in Ireland it is said to be often present in thousands. It frequents salt-water lochs and inlets, and though it occasionally wanders inland is on the whole more maritime than the Whooper. Its flight call is quite distinct, a sharp, repeated, barking note, loud and metallic ; a puntsman I knew described a herd as yelping 'just like a lot of poodle puppies." Mr. H. W. Robinson records that at night, on one of the Inner Hebrides, he re- peatedly heard the " song," which "consists of the full octave, and both ascends and descends " ; once he heard it in the daytime. Many writers slate that wild swans sometimes show a reddish or ochreous tinge on the head and neck, and Mr. W. P. Pycraft has seen a dark copper hue. Years ago, however, Stevenson pointed out that this is due to peroxide of iron staining the plumage when the bird is feeding in certain waters. Mr. Jourdain saw a Whooper deeply stained after feeding in a peat bog, and I have seen Mutes deep red on the head and neck on a pool where the weed and mud is thickly covered with iron deposit. •^^^"i -W" "W^
