Part 24
The common sheldrake is a bird that, once seen, cannot be easily forgotten, its strange guinea-pig arrangement of three colours--black, white, and red--making it one of the most strikingly conspicuous fowls in this country. On account of its handsome and singular colouring it is much persecuted, and as a breeding species is becoming increasingly rare with us. It inhabits sandy sea-coasts, and is only seen as a rare straggler on inland waters. It feeds close to the shore where the sea is shallow, and is partial to coasts where wide stretches of sand, mixed with rocks, are uncovered at low water. It feeds, both in the water and on the flats, on marine insects and molluscs, and breeds in the sandhills along the coast. The nesting-hole is in most cases a deserted rabbit-burrow, but it also burrows for itself, and is known as the ‘burrow-duck’ on many parts of the coast. The hole is six to twelve feet in length, ending in a chamber lined with dry grass and moss. Seven to twelve creamy white eggs are laid, sometimes a larger number. The eggs are enveloped in a quantity of down, which the bird plucks from her own body. It is said that the male takes no part in incubation, but remains near the burrow on guard, and gives timely warning of danger, and when the young are hatched and taken to the sea, assists in rearing and protecting them.
The sheldrake has a harsh cry, but in the breeding season the drake utters a soft, tremulous, whistling note.
Wigeon.
Mareca penelope.
[Illustration: FIG. 79.--WIGEON. ⅐ natural size.]
Bill dull blue; forehead and crown cream-white; chin, neck, and throat chestnut; the cheeks and hind neck minutely spotted with deep green; breast white; under parts grey, the flanks pencilled with dark grey; mantle vermiculated grey; shoulder white, with a terminal bar of black, followed by a green speculum tipped with black below; wing- and tail-feathers dark brown; legs and feet dark brown. Length, eighteen inches. _Female_: above, mottled greyish brown; shoulder whitish; speculum greyish green; under parts mottled buffish white. The drake assumes female plumage in July.

Next to the mallard, the wigeon is the most familiar freshwater duck in the British Islands. Its abundance, handsome plumage, peculiar voice, and interesting habits, to say nothing of its excellence as an article of food, contribute to make it well known. It is a visitor in winter in very large numbers to our coasts, and seeks its food both on the tidal flats and on inland waters throughout the country, but is always most abundant in the vicinity of the sea. In April and May it migrates to higher latitudes: in Scotland it is partly a resident species, and breeds in many localities; and, in less numbers, it also remains to breed in Ireland. The wigeon differs a good deal from other ducks in its feeding habits: it feeds both by day and night, in the water and on land. On land it is, like the goose, a grass-eater, and in Lapland is known from this habit as the ‘grass-duck.’ In disposition it is one of the shyest and wariest; and at the same time the most gregarious, among the waterfowl, and often unites in immense flocks. It is also very loquacious: its loud, prolonged whistle in two syllables, strongly accented on the first, is described by Seebohm as being ‘very wild and weird, as it startles the ear on the margin of a mountain tarn or moorland lake--a solitary cry, very high in key, not unmusical in tone, but loud and piercing.’ It is called ‘whew duck’ in some localities, from its whistling cry.
The nest is placed amidst coarse grass or heather, and is deeply lined with down. The eggs are seven to ten in number, and cream-coloured.
* * * * *
A few specimens of the American wigeon (_Mareca americana_) have been obtained in various parts of Great Britain.
Pintail.
Dafila acuta.
Head and neck bronze-brown, black on the nape; a white stripe down the neck on each side, extending to the white breast and under parts; back and flanks mottled grey; greater wing-coverts buff; speculum green margined with black and white; tail black, the two middle feathers greatly prolonged; under tail-coverts black; bill, legs, and feet slaty grey. Length, twenty-eight inches. _Female_: mottled brown above and greyish white below; speculum green. In July the male assumes the female dress, and retains it until October.
* * * * *
The pintail, although not so handsomely coloured as the shoveler, mallard, wigeon, and teal, is the most elegant of the freshwater ducks, being slim and graceful in form, with the two slender middle feathers of the tail greatly elongated. Sea-pheasant is one of its local names, but the same name is sometimes given to the long-tailed duck (_Harelda glacialis_) on the north-east coast. The pintail is a winter visitor only to the British Islands, appearing in October, and is most common on the south coast. It is found in small flocks, and prefers shallow waters with muddy bottoms, and feeds on aquatic weeds, insects, and crustaceans. It is always most abundant near the shore, but is also met with on inland waters. It has a rapid flight, and is a comparatively silent bird by day; its cry by night is a low quack, and in spring, during courtship, the drake utters soft and inward notes, which he accompanies with some curious gestures and antics. The pintail breeds freely in a semi-domestic state, and lays seven to ten eggs, pale buffish green in colour.

Mallard, or Wild Duck.
Anas boscas.
Bill yellowish; head and neck glossy green, followed by a white ring; hind neck and breast deep chestnut; across the secondaries a greenish purple speculum, bordered above and below with white: rump, upper tail-coverts, and the four middle curled tail-feathers black; the rest of the tail-feathers grey; flanks and belly greyish white; under tail-coverts velvet-black; legs and feet orange-red. Length, two feet. _Female_: smaller; bill greenish; crown dark brown; general plumage mottled brown and buff; speculum green.

The mallard is the most common and best-known freshwater duck in Britain, and is a resident species, breeding in suitable localities throughout the country; but the birds that breed and remain all the year are few in number compared to the migrants that come to us in winter from more northern regions. In the domestic state the mallard is, next to the fowl, the most abundant and familiar bird we possess. The tame duck differs from the mallard only in its heavier body and shorter wings, and in being polygamous instead of monogamous in its habits. The tendency to vary in colour is a result of domestication in all species. It was from observing the annual change in the plumage of the domestic drake that the discovery was made that ducks differ from other birds in the manner of their moult. The period of the moult does not coincide in the drake and duck; and this discrepancy in the sexes has caused ducks to differ in their breeding habits from all other birds. Thus, in most birds, male and female share the labours of incubation, and of rearing and protecting the young; and the moult, which is always a period of danger, during which the bird is obliged to go into hiding, takes place some time after the young are able to shift for themselves--in other words, the family tie is broken after it has ceased to be necessary; and the female of the mallard, and of other ducks, moult in this way. Not so the male. He is smitten by the change after the eggs are all laid and incubation begun; with the result that the marriage tie is dissolved just at the period when his help is most needed. This is one of the strangest things in bird history; for up to the time when the physical change begins the drake is not less loving and solicitous than any other male bird, and if by chance the moulting period is delayed, he continues to guard the nest and share the labours of incubation; so that we may say, without straining a metaphor, that the drake is forcibly torn away from his marital duties, just as the late-breeding swift or swallow is sometimes forced by an overpowering migratory instinct to abandon its helpless young in the nest. The action of the swift in leaving its helpless young to perish of starvation in the nest is painful to contemplate, since we are accustomed to look on the parental affection as the most powerful of all; and in this case there is a conflict between this emotion and another--the desire for another climate; and the last conquers, and the young are forsaken. In the drake it is not a case of a conflict between two emotions or two instincts, but of a physical change, which kills or makes nugatory the instinct and emotion; for it is certain that the moulting period in all species that, like the duck, change their whole plumage in a short time, is not only a period of danger, but of suffering. When the change comes the bird acts like the ‘stricken deer,’ and like animals afflicted with some fatal disease: he goes apart, and remains in hiding until his new plumage has grown, and with renewed health his social instincts are restored. It is only in the case of the male duck that this change from health and strength to sickness and impotence falls in the midst of the breeding season.
[Illustration: MALLARDS. PEREGRINE FALCON. HERON. COOT.]
Another extraordinary fact about the moulting of the drake is that, in moulting, he puts on the dress of the female. The moult is complete, but only after the whole of the small feathers have been changed are the wing- and tail-feathers shed, and as these are all shed at once, the bird is for some time incapable of flight. But while in this incapable condition he is no longer a drake in appearance--a bird of rich and conspicuous colouring--but has a dull mottled brown like the duck. This annual ‘eclipse,’ as Waterton called it, lasts for three or four months; and then there is a second, autumnal moult, of the body-feathers only, in which the rich colours of the male sex are recovered.
The duck, in the meantime, moults only once in the year.
A slight difference has been noted between the resident mallard that breeds in the British Islands and the mallard from the north that visits us in winter, the native bird being heavier.
Gadwell.
Chaulelasmus streperus.
Beak lead-colour; head and upper neck light brown with darker mottlings; back marked with crescents of light grey on a dark ground; median wing-coverts chestnut; greater coverts blackish; primaries brown; secondaries brown and black, the outer webs forming a white speculum; rump and upper tail-coverts bluish black; tail-feathers dark brown with pale edges; lower neck dark grey, each feather with a pale grey margin; breast and belly white; flanks and vent grey; under tail-coverts bluish black; legs and feet orange. Length, twenty-one inches. _Female_: head and upper neck light brown mottled with dark; lower hind neck and upper parts brown; speculum and under parts white.
* * * * *
[Illustration: FIG. 81.--GADWELL. ¹⁄₁₀ Natural Size.]
The gadwell most nearly resembles the mallard, but is not so richly coloured, and is smaller in size. It is a widely distributed species, ranging over a greater portion of the northern hemisphere. In the British Islands it is a winter visitor in small numbers, very few pairs remaining to breed, except in one locality in Norfolk, where it has been strictly protected for the last forty years, with the result that it breeds regularly, and is abundant. Elsewhere it is the rarest of the British freshwater ducks. The wings are long and sharply pointed, and the flight exceedingly rapid. When flying it frequently utters its cry, which resembles that of the mallard, but is shriller in tone. Like the mallard, it is a night feeder; during the daylight hours it usually remains concealed in the closest cover. Its nest, lined with dry grass and a quantity of down, is placed on the ground at some distance from the waterside. Eight to twelve buffish white eggs are laid.
Garganey.
Querquedula circia.
[Illustration: FIG. 82.--GARGANEY. ¹⁄₁₁ natural size.]
Bill black; forehead, crown, nape, and back dark brown; from the eye a white stripe extending to the back of the neck; cheeks and neck light brown with short hair-like lines of white; scapulars black, with central white stripe; wing-coverts bluish grey; speculum green between two bars of white; primaries and tail dull brown; chin black; breast pale brown with dark crescentic bands; belly white; flanks with transverse black lines; under tail-coverts black and white; legs and feet greyish brown. Length, sixteen inches. _Female_: mottled brown; stripe over the eye yellowish white; speculum dull metallic green between two white bars.
* * * * *
The garganey, or summer teal, or cricket teal, as it is sometimes called, on account of the low, jarring note of the male in the pairing season, differs considerably from its nearest relation, the common teal, both in its larger size and its colouring, which a little resembles that of the shoveler. It is an early spring visitor to the British Islands, rare in England, and still rarer in Scotland and Ireland. It remains to breed in suitable localities in this country, and is perhaps most common in the district of the Broads in Norfolk. It flies swiftly, and utters on the wing a sharp, quacking cry, sometimes repeated twice. Its feeding habits are similar to those of the teal, but it is not esteemed a good bird for the table. The nest is made among the coarse grass and herbage in swampy ground; eight or nine creamy white eggs are laid sometimes a larger number.
Teal.
Querquedula crecca.
Bill blackish; crown, cheeks, neck, and throat chestnut; round and behind the eye an elongated patch of glossy green margined with buff; upper parts and flanks delicately marked with black and white; speculum black, green, and purple, tipped with yellowish white; rump and tail-coverts black; tail-feathers brown; front of neck spotted with black on a buff ground; breast and belly white; legs and feet brownish grey. Length, fourteen inches and a half. _Female_: mottled brown; little or no purple on the speculum. The female dress is assumed by the drake in July, and is kept until October.

The handsome and natty little teal is the smallest of our ducks, its weight being only one third that of the mallard. In appearance it is a small wigeon, but whereas the wigeon is the wildest of our wild ducks in disposition, the teal is the tamest. It is chiefly a winter visitor to this country, and from September until spring is found throughout the British Islands. A considerable number of pairs remain to breed in suitable localities throughout England, and more numerously in Scotland and Ireland. The nest is placed on the ground on the borders of a marsh or bog, and sometimes at a distance from water, among heather or herbage; it is made of dry grass and leaves, and, later on, down from the bird is added. The eggs are creamy-white or pale buff in colour, with a tinge of green, and eight or ten in number, sometimes as many as fifteen. The teal feeds chiefly by night, on aquatic plants, insects, slugs, and small crustaceans. Its call-note is a short, sharp quack, and in the pairing-time the drake emits a low, jarring note. The drake does not moult so early as most ducks, and remains longer with the female during the breeding season, leaving her only when the young are partly grown.
* * * * *
Two American species of teal--the blue-winged teal (_Querquedula discors_) and the green-winged teal (_Q. carolinensis_)--have been obtained in Great Britain, one specimen of each.
[Illustration: PLATE X. TEAL (MALE AND FEMALE). ⅓ NAT. SIZE.]
Shoveler.
Spatula clypeata.
Bill lead-colour, very broad at the tip; head and upper neck green; lower neck and scapulars white; middle of the back dark brown; shoulders pale blue; greater wing-coverts white; secondaries dark brown with a green speculum; primaries, rump, upper and under tail-coverts, and tail-feathers, blackish; breast and belly rich chestnut; flanks freckled with dark brown on a paler ground; vent white; legs and feet reddish orange. Length, twenty inches. _Female_: brown with dark and light mottlings. In summer, the male in moulting assumes the colours of the female.
* * * * *
The shoveler is the handsomest of the British freshwater ducks, and the most singular in appearance, on account of the great breadth of its spoon-like bill. Its plumage also, although beautiful, strikes one as somewhat singular; for it is rare to find pale and delicate hues, like those on the wings and upper parts of this duck, together with a deep, rich colouring, as on the head, upper neck, and under parts. The pale blue and pure white contrast beautifully with the deep green and chestnut-brown. Another most interesting point in the shoveler’s history is its distribution. There is but one shoveler duck in the northern hemisphere, over which it has an immense range, including Europe, North Africa, Asia, and North America from Alaska to Panama. But in the southern hemisphere there are four other species, occupying respectively the four following widely separated regions--South America, South Africa, Australia, and New Zealand.
The shoveler is a winter visitor to the British Islands; it also breeds sparingly in some localities in the Midlands, in East Anglia, and the northern counties; also in the Hebrides, and in one or two spots in Ireland. It is a very early breeder, placing its nest, lined with dry grass and down, on the ground, usually near the water, and it lays eight to fourteen eggs, pale greenish buff in colour.
In the breeding season it utters a low quack, but at other times is a silent bird.
Tufted Duck.
Fuligula cristata.
[Illustration: FIG. 83.--TUFTED DUCK. ¹⁄₁₁ natural size.]
Black, the head and neck with purplish gloss; speculum, flanks, and belly white; bill pale blue; irides brilliant yellow; legs and feet dark blue. Length, seventeen inches. _Female_: dark brown; under parts brownish grey. Male changes colour in May.

Of sea or diving ducks (including the mergansers) no fewer than twenty species, referable to nine genera, have been described as ‘British.’ Of this number nine species are irregular visitants or stragglers, and may be dismissed with a mention of their names: Red-crested pochard (_Fuligula rufina_), white-eyed duck (_Nyroca ferruginea_), Barrow’s goldeneye (_Clangula islandica_), buffel-headed duck (_C. albeola_), harlequin duck (_Cosmonetta histrionica_), Steller’s duck (_Heniconetta Stelleri_); king eider (_Somateria spectabilis_); surf-scoter (_Œdemia perspicillata_), and hooded merganser (_Mergus cucullatus_).
Of the eleven species, referable to six genera, that breed in, or regularly visit, these islands, and may properly be described as British birds, three are mergansers, the least duck-like of the ducks in their curiously modified beaks and grebe-like habits. Of the other eight species, four only are, strictly speaking, sea-ducks, being (on our coasts) exclusively marine in their habits. These are the eider, the long-tailed duck, the common scoter, and the velvet scoter. The tufted duck, pochard, and goldeneye, are marine and freshwater ducks. The scaup is more of a sea-duck than these three, and may be said to be intermediate in its habits between the two groups.
These eight diving ducks are all interesting, and some of them very handsome birds in their richly coloured and conspicuous plumage. They have stout, heavy-looking figures, and are clumsy walkers on land; but in the water they are as much at home as grebes and guillemots, and are also strong on the wing. But they are not so familiar to us as the mallard, wigeon, and teal, as comparatively few persons have the opportunity of observing them. Mr. Abel Chapman, in his valuable work, ‘Bird Life on the Border,’ says that these ducks are only well known to those ‘who are enthusiastic enough to follow the regular sport of wildfowling afloat, and who alone enjoy the opportunity of becoming acquainted with these wild creatures in their bleak and desolate haunts.’
The tufted duck is a winter visitor to our coasts, also a resident throughout the year, and a regular breeder in various localities in England, Scotland, and Ireland. In winter it is both a sea- and freshwater duck; in the breeding season it is exclusively an inhabitant of inland waters, with a preference for small ponds with weedy bottoms. It pairs in March, and male and female thereafter keep company until incubation begins, when the marriage tie is dissolved, as is the case with most ducks. It feeds chiefly by night, and is inactive by day, floating lazily on the water, dozing, or preening its feathers. At sunset it leaves the pool where it has passed the day, to seek its feeding-grounds. Its food consists of weeds growing at the bottom, for which it dives, and, tearing them up, brings them to the surface, to be eaten at leisure.
The nest is placed among the rushes at the waterside, or in the centre of a tuft of aquatic grass, and is composed of dry sedges and grass, to which down is added as incubation progresses. Eight or ten eggs are laid, sometimes more, greenish buff in colour.
When rising from the water it utters a grating cry. In winter it is gregarious, and is often seen associating with the scaup, pochard, and goldeneye.
Scaup.
Fuligula marila.
Head, neck, upper breast, and back glossy black; mantle finely vermiculated with greyish brown and white; speculum white, terminated with greenish black; rump, wing- and tail-feathers brown; belly white; bill pale blue; irides straw-yellow; legs and feet dull blue. Length, eighteen inches. _Female_: brown; a broad white band round the base of the bill; upper breast and mantle vermiculated with grey; belly dull white.
* * * * *
The scaup is common with us in winter, and found on most parts of the coast, but never remains to breed. It does not come inland, like the tufted duck and goldeneye, but is met with in estuaries and the mouths of tidal rivers. In its breeding-haunts in the extreme north of Europe it penetrates to lakes and rivers at a considerable distance from the sea. It feeds on shellfish, crustaceans, aquatic insects, also on vegetable food, which it obtains by diving. It is gregarious at all times, and in the breeding season is seen in small flocks, feeding or floating idly on the water. It rises heavily, and flies rapidly, with violently-beating wings. Seebohm, who observed it in its summer haunts, says of its language: ‘Of all the cries of ducks that have come under my notice, I think that of the scaup is the most discordant. None of them are very musical, perhaps; but if you imagine a man with an exceptionally harsh, hoarse voice, screaming out the word _scaup_ at the top of his voice, some idea of the note of this duck may be formed.’
The scaup makes its nest near the water, and lays from six to nine eggs, of a pale greenish grey colour.
Pochard.
Fuligula ferina.
Head and neck chestnut-red; breast and upper back black; mantle finely freckled with black and white; speculum inconspicuous and grey; under parts greyish white; tail-coverts black: bill black with a blue band across the middle; irides red; legs and feet bluish grey. Length, nineteen and a half inches. _Female_: dull brown; chin white.
