British Sea Birds

VELVET SCOTER

Although this species, the Fuligula fusca of ornithology, is a regular winter visitor to the seas off the British coasts, it nowhere approaches in numbers the preceding species. It may be readily distinguished from the Common Scoter by its very conspicuous white wing bar, and less observable white spot under the eye; otherwise it closely resembles it in general colouration. The Velvet Scoters that visit our seas are generally observed mixed with the gatherings of the Common Scoter. The habits of the two species are much alike in some respects, very different in others. Thus it exhibits the same skill in diving for food, and obtains it under very similar conditions; its flight is equally rapid and well sustained; it seldom visits the land, and is, when on it, just as clumsy and waddling in its gait; its food is similar; its migrations take place at much the same periods. On the other hand, the Velvet Scoter is not such a strictly maritime species, being frequently found on inland waters, and even, during winter, is partial to wandering up tidal rivers and visiting lakes. Its breeding-places are also, as a rule, much farther from the sea, and the nest is not unfrequently found at long distances from any water at all. Odd pairs of this Scoter are occasionally met with in our area during the summer, and it has been suggested that the species even breeds within the British limits; no direct evidence, however, is forthcoming.

This Scoter is a late breeder, its eggs not being laid before the end of June, or even early in July. Although migrating in flocks, the birds appear to separate into pairs as soon as the summer quarters are reached. The duck and drake keep close company as usual, until the eggs are laid, after which the latter leaves his mate to bring up the brood alone. The Velvet Scoter breeds in the Arctic and sub-Arctic regions of Europe and Asia, from the Atlantic to the Pacific, and winters in temperate latitudes. The breeding-places are chiefly situated on the tundras, amongst scrub or coarse vegetation, near the rivers and lakes. The scanty nest of dry grass and dead leaves is often made under some bush, and, before incubation commences, is lined with down from the body of the female. The eight or nine eggs are greyish-buff in colour, smooth, and with little gloss. As soon as the young are capable of flight, a movement south is made.

SCAUP DUCK

This Duck, the Anas marila of Linnæus, or Fuligula marila of modern naturalists, derives its trivial name from its habit of frequenting the “mussel-scaups,” or “mussel-scalps,” and is tolerably abundant round the British coasts during winter. The adult male is distinguished by having the head and neck black, shot with metallic-green and purple, and the back and scapulars vermiculated with white and black. The general colour of the female is brown, shading into grayish-white on the belly, whilst a broad white band extends round the base of the bill. Scaup Ducks begin to arrive off our more northern coasts in September, but not until a month later in the south. They begin to leave us again in March, and the migration continues through the whole of April into May, the bird thus being one of the last Ducks to retire north in spring. Although by no means unfrequently met with on inland waters during migration and in winter, the Scaup Duck is, for the most part, a dweller on the sea, resorting, by preference, to bays, estuaries, and the mouths of large rivers, especially where a considerable amount of mud is left bare at low water. It is gregarious at this season, often congregating into large flocks, and not unfrequently associates with other Sea Ducks, notably with Wigeon and Pintail. It is a most expert and ready diver, spends most of its time upon the water, and appears always to prefer to dive, rather than to fly, in avoiding pursuit. If compelled to take wing, it rises with much splashing: but, when once fairly in the air, is capable of rapid flight, the quickly-beating pinions making a whistling or rustling sound. The food of the Scaup Duck consists largely of molluscs, but crustaceans and marine plants are also eaten by this species. When thus diving for food, the bird often remains below for a minute at a time. It feeds much at night, and passes pretty regularly from its usual haunts by day to its feeding-places. The note of this Duck is a most harsh and discordant scaup, but during flight or courtship a hoarse and grating kurr is uttered.

The Scaup Duck arrives at its Arctic breeding-grounds with the break-up of the ice. The bird may probably pair for life, as the sexes keep close company all the year. Even at its breeding-grounds it is a social bird, many pairs nesting in a small area, and collecting at certain spots to feed. Its breeding-grounds are on the Arctic tundras, near the rush-and-grass-fringed lakes, amidst the thickets of birches, junipers, and willows. The nest is placed under a bush, or amongst herbage on a bank, and is merely a hollow lined with dry grass and sedge and dead leaves. To this, however, the usual lining of down is added. The eggs, from six to nine in number, are greenish-gray, and of smooth texture. The female, as usual, takes sole charge of the young. The Scaup Duck inhabits, during summer, the Arctic regions of Europe, Asia, and America, drawing southwards in winter almost to the tropics.

TUFTED DUCK

This species, the Anas fuligula of Linnæus, and the Fuligula cristata of most modern ornithologists, is a fairly common winter visitor to the British coasts. It is not so exclusively a marine species as some of the other diving Ducks, being often met with on inland waters during that season. The Tufted Duck derives its name from the bushy crest or tuft of feathers growing from the top of the head, and drooping down over the back of the neck on the male. The head, neck, and crest are glossy black, shot with purple and green; the upper parts, the breast and the under tail coverts, are black; the remainder of the underparts and the alar speculum are white. In the female, the black is replaced by dark brown, and the white with brownish-gray: the white speculum remains. Many Tufted Ducks breed, and are apparently resident in our islands in certain inland districts; but the majority of the birds that occur round the coasts are migrants from the north. This Duck begins to arrive off the British coasts towards the end of October, and continues to do so into November. It remains in our area until the following spring, passing north in March and April. Its principal haunts are the more low-lying coasts, especially in the vicinity of estuaries and mud-banks. It is gregarious enough at this season, some of the flocks consisting of many thousands of birds. In its habits generally, it very closely resembles the Scaup Duck, a species whose company it often keeps. It swims in much the same low manner, dives with equally marvellous adeptness, and shows the same propensity for keeping well out to sea during the day, coming shorewards and into shallower water at night to feed. It rises from the sea in the same apparently laboured way, striking the water with its feet – the splashing thus made by a flock of birds being audible for a long distance. Its alarm note during winter is a harsh kurr, but the bird is not a very noisy one. The food of this Duck consists of molluscs, small fish, and the roots, stems, leaves, and buds of various water plants – all of which is obtained by diving, the bird sometimes remaining beneath the surface for as long as a minute.

The Tufted Duck retires to inland waters for the summer, its favourite resorts being meres, lakes, and marshy grounds full of small ponds. A partiality is also shown for small pools on heaths, or fairly well-timbered ground. This Duck probably pairs for life; in the breeding season it is certainly social, many males consorting together, and many females making their nests within a small area. The nest is usually made in a tussock of sedge, beneath a bush, or amongst rushes and coarse grass, and is a mere hollow lined with a little dry vegetation, and an abundance of down from the female. The eggs are usually from eight to ten in number, and greenish-buff. They are laid, according to locality, from April to June. The female alone brings up the young. Outside our islands, the Tufted Duck breeds in the Arctic or temperate parts of Europe and Asia, visiting the southern portions of those continents, as well as North Africa, during winter.

POCHARD

This handsome Duck, the Anas ferina of Linnæus, and the Nyroca or Fuligula ferina of modern writers, is another winter visitor to the British Islands, where, however, it breeds locally, and in somewhat limited numbers, thus coming within the category of our resident species. In some districts the male of this Duck is known as the “Red-headed Poker,” the female as the “Dunbird” or “Dunker.” The colours of this Duck are very distinctive. The head and neck of the male are rich chestnut; the back scapulars and flanks are white, finely-pencilled or vermiculated with black; the gorget and tail coverts are black; the under-surface grayish-white; the quills brown. The female has the head and neck reddish-brown, the chin white, and the remainder of the plumage much browner and more dingy than in her mate. The Pochard is by no means exclusively a marine Duck; in fact, this species appears to be as much attached to fresh-waters as to the sea. Unfortunately, there is one thing about most of these Sea Ducks which does much to detract from their interest, and that is, they cannot readily be observed from the shore, and appear upon our seas at a season when the elements render the coast least attractive. Most of these Ducks lie well off the land, where the wild-fowler alone is tempted to follow them; or if approaching the shore more closely, it is generally during rough tempestuous weather, when all but the enthusiastic naturalist and the gunner prefer to remain warm and comfortable at home. The Pochard is no exception in this respect. It arrives along our coasts in October, and remains with us until the following March. It is thoroughly aquatic in its habits, rarely visiting the land, feeding both by day and by night (chiefly the latter), and often flying for considerable distances, about dusk, to waters where food is abundant. Although its flight, at first, is slow and laboured, it soon becomes very rapid, and the quickly-beating wings make a rustling sound very characteristic of this species. The Pochard is another expert diver, and by this means obtains most of its food, visiting the bottom and bringing up masses of weeds to eat them on the surface. On the coast its food largely consists of crustaceans and molluscs, as well as marine plants. The note of this species is a loud and harsh kurr.

The haunts of the Pochard in summer are large and open sheets of water, surrounded by a luxuriant growth of sedge, rush, iris, and similar plants, or situated on higher ground clothed with heath, gorse, and coarse grass. It is a social bird during the breeding period, several females often nesting close together. The nest is always made near fresh water, and in many cases absolutely floats on rafts of fallen and rotting vegetation several yards from the bank, or rests in some tussock surrounded by shallow water. A bed of iris, or a crown of rushes, is another favourite spot. It is made of dry grass and fragments of any aquatic vegetation obtainable, and lined with down from the female’s body. The eggs – usually from eight to twelve, sometimes more – are brownish-gray. As is usual among Ducks, the female alone brings up the numerous family. This Duck is widely distributed over many parts of Europe, Northern Asia, and North America, the birds of the latter continent being regarded by some ornithologists as a distinct species.

GOLDEN-EYE

Misled by the variations of colour, due to age, sex, or season, in this species, Linnæus described different examples of it under the names of Anas clangula and A. glaucion; whilst even in our own day the females and immature birds are known as “Morillons,” and regarded as distinct from the much-rarer adult males or “Golden-Eyes,” which are locally termed “Rattle wings” or “Whistlers” from the noise produced by the wings during flight. The Golden-Eye forms the type of the well-marked genus Clangula of Fleming and of Boie, and is known to most modern ornithologists as C. glaucion. The male is a singularly striking and beautiful bird, with the general colour of the upper parts black, shot with metallic-green tints on the head, which is adorned with a small, yet distinct, drooping crest; with a large white patch at the base of the bill under each eye, and with the drooping, elongated scapulars, and the underparts, white. The female is much less conspicuous, the black being replaced by dark brown, the elongated scapulars are wanting, and the spot under the eyes only faintly indicated. The white double alar speculum is, however, very strongly marked in both sexes. The Golden-Eye is certainly more addicted to fresh-water than the sea, and in most cases only quits these inland lakes and ponds, when continued frost compels it to do so. It then prefers such coasts as are low-lying, especially delighting in estuaries. It usually arrives in the British Islands in October, and remains in them until the following April or May. It is not so gregarious as some of the other Ducks, and generally assembles in parties rather than in flocks, the larger gatherings being caused by exceptional circumstances. Its habits very closely resemble those of allied birds. It is seldom seen on the land, and there walks with the waddling gait peculiar to most Ducks; on the water, however, it is active and graceful enough, swimming well, and diving with great celerity, usually seeking by this means to escape from danger. The note of this Duck is a low croaking kurr, uttered both when the bird is flying and when at rest. Its food consists of crustaceans, molluscs, small fishes, and various water plants and weeds. Most of this is obtained by diving; and whilst a flock of birds is feeding, several individuals keep watch, all never diving together.

The evidence for this Duck having bred in Scotland, is neither reliable nor conclusive. The Golden-eye breeds throughout the Arctic and sub-Arctic regions of Europe, Asia, and America, up to the limits of the growth of trees: its winter range extends to the tropics. It retires to its northern summer haunts with the first signs of spring. The favourite breeding resorts of this Duck are tracts of more open forest country, where the woods are full of swamps and lakes, and the timber contains plenty of holes. The nest is usually made in a hollow tree, in a hole in the trunk, or in a hollow branch, sometimes as many as thirty feet from the ground; whilst the partiality of the bird for a tree near a waterfall, or running stream, has been noticed by more than one observer. The nest consists entirely of the down plucked from the female’s body. The ten or twelve eggs are laid in May or June, and are bright green in colour. The nest-hole is never made by the Duck itself. The peasants of Northern Scandinavia place hollow logs in suitable places on the tree-trunks, which the Golden-Eyes appear readily to avail themselves of, and from which the eggs and down are systematically taken. The young are conveyed to the ground, one by one, pressed between the female’s bill and her breast. The male is not known to assist in the task of incubation, but may possibly do so.

LONG-TAILED DUCK

This beautiful and remarkably elegant species, the Anas glacialis of Linnæus, and the Fuligula or Harelda glacialis of modern writers, is another winter visitor to the British seas. It is only of somewhat rare occurrence in our southern waters, but northwards, off the Scotch coasts, it becomes more frequent, and in certain localities – notably the Hebrides, and the Orkneys and Shetlands – even abundant. In the latter islands it is locally known as the “Calloo”; in other parts of Scotland the clear, gabbling cry of this Duck has been freely translated into the words “coal-an’-can’le-licht.” To many American gunners the bird is known as “Old Squaw,” from its oft-repeated cries. The male bird is singularly graceful in appearance, his long, black central tail feathers projecting five inches beyond the remaining white ones. The head and neck are white, but on either side, below the ears, is a dark brown circular patch; the gorget and the upper parts generally are black, against which, however, the long, elongated white scapulars are very conspicuous; the underparts, below the gorget, are white. The female is much less showy, the black parts in the male being dark brown in this sex, and the white parts are suffused with brown; the elongated scapulars are wanting. During exceptionally severe weather the Long-tailed Duck sometimes approaches our coasts in unusual numbers, and in districts where it is generally a scarce bird. This Duck is a late migrant, seldom reaching even our most northerly coasts before November. It returns north in April. It is strictly marine in its haunts during winter, often wandering long distances from land, and approaching the shore usually under pressure of stormy weather. Then it shows a decided preference for rock-bound coasts, frequenting the creeks and inlets which afford a considerable amount of shelter. The Long-tailed Duck is gregarious at this season, like most of its kind, although the flocks are seldom or never so large as the gatherings of Scoters and others. Its flight is remarkably quick, the long tail making the bird look extremely elegant. It is also an expert diver, disappearing as quick as thought, and often going for long distances beneath the surface, like a Grebe or a Shag. It obtains most of its food by diving, and, like the Eider, often comes shorewards with the tide. It feeds in deeper water, too, than many of its allies, as much of its prey is captured, not at the bottom, but floating in the sea. This food consists of small molluscs, crustaceans, minute marine animals, insects, and water plants, and weeds. Its note may be described as a loud cal-loo-oo.

The Long-tailed Duck breeds in the Arctic regions of Europe, Asia, and North America, above the limits of forest growth, and, possibly, as far north as land exists. During summer, it frequents inland pools and lakes; odd pairs taking possession of the former, many pairs congregating on the latter. The birds arrive in the Arctic regions with the break-up of the ice, congregating in the pools amongst the floes. The nest is usually placed in some sheltered nook, amongst birch and willow scrub, in long grass, or on the drifted rubbish by the banks of the subsided rivers. It is little more than a hollow, lined with down. In this, during June or early July, from seven to twelve buffish-green eggs are laid by the female. It is a most remarkable fact that the drake of this species assists the duck in bringing up the young, but not, so far as I can learn, in incubating the eggs. During the whole breeding season this Duck is remarkably tame, loth to take wing, and swimming out into the centre of the lake for safety, if threatened by danger. The winter migrations of this Duck are not very extended, the Mediterranean Basin, perhaps, marking the extreme southern limits.

MERGANSERS

The Mergansers are a well-defined little group of fish-eating Ducks, forming the sub-family Merginæ. They are characterised by their slender, narrow bill, furnished on both upper and lower mandible with saw-like lamellæ or denticulations. The head is always more or less crested; in most other respects they resemble the Diving Ducks, all the species seeking for their food by diving. The sexes differ in colour of plumage, but not, perhaps, to such a marked extent as in some other divisions of the Anatidæ. Six species of Mergansers are known to science, of which four are included in the British list – one as a rare visitor from North America. Of the remaining two species, one inhabits South America, the other the Auckland Islands. The young, as usual, are hatched covered with down, and able soon to follow the female to the water. In their moulting and progress to maturity they resemble preceding species.

RED-BREASTED MERGANSER

This handsome sea-bird, the Mergus serrator of Linnæus and most modern ornithologists, is unfortunately a winter visitor only to English waters. In Scotland and Ireland, however, it is one of the most familiar coast birds all the year round. The Red-breasted Merganser cannot readily be confused with any other Duck. The crested head and upper neck are black, shot with green and purple, the lower neck and upper breast are buff, streaked with black, the feathers on the sides of the breast having broad black margins, the flanks are strongly vermiculated with black, the back is black, vermiculated with gray on the lower portions, the inner scapulars are black, the outer ones white, the speculum is white, barred with black, and the underparts (except the flanks) are white. The female has the head and neck reddish-brown, and the upper parts brown, the black-bordered feathers on the sides of the breast are absent. Although found in many inland districts, the favourite resorts of the Red-breasted Merganser are wild, rocky coasts, such as contain plenty of quiet bays and creeks, and lochs studded with islands. Waters where the bottom is sandy or rocky, are preferred to those in which it is composed of mud. Many birds of this species visit our coasts for the winter from more northern haunts, whilst some of those dwelling in Scottish waters draw southwards at that season. This Merganser is more or less gregarious, and may be met with in flocks out at sea, or during rough weather sheltering nearer the land in lochs. Early in spring, and onwards through the summer, the Red-breasted Merganser lives closely in pairs, flying and feeding in company. I have noticed that this bird visits certain spots to feed very regularly, according to the state of the tide; almost to the minute I could depend upon certain pairs passing certain spots on their way to these feeding-grounds. I know of few prettier sights than the actions of a pair of Mergansers in some quiet, deep sea loch in early summer. The birds swim side by side close inshore below the rocks, first one diving, and then another, rarely, if ever, both descending at the same time when feeding; but when engaged in courtship, the drake will pursue the duck, and splash about in the water in a most uproarious way, often diving after her in the eagerness of his chase. The bird swims well, if rather low in the water, and dives head foremost with a leap just like the Shag. The food of this species consists largely of fish, but crustaceans, crabs especially, and molluscs are also devoured. Most of this food is obtained whilst diving, each capture being brought to the surface to be swallowed, the bird drinking after doing so, and not unfrequently rising three parts out of the water and flapping its wings. The note is a guttural kurr, heard chiefly during flight. The bird flies well and rapidly when once free from the water, but often flaps along the surface for several yards before that is accomplished.

The Red-breasted Merganser breeds in May, the eggs being laid during the latter half of that month, and the first half of June. Although not gregarious during this period, it is, at any rate, social, for several pairs may be found nesting very close together, if keeping somewhat to themselves. An island is always preferred to the mainland. The nest is placed under a rock or bank, in a rabbit burrow, or amongst dense heather and gorse at no great distance from the water. In many cases the eggs are laid upon the bare ground, in others a few dry vegetable fragments are collected into a slight hollow, but a plentiful bed of down gradually accumulates around them. From eight to twelve olive-gray eggs are laid, upon which the female alone sits. The male, however, is in attendance on the water near by, and the duck joins him there during the short periods that she leaves her charge to feed and to bathe. If alarmed, the hen bird slips off very quietly. When the young are hatched the drake retires to moult, and the female brings them up unaided. Outside our islands this Merganser is widely distributed over the northern parts of Europe, Asia, and America, drawing southwards in winter.

GOOSANDER

As this beautiful Duck, the Mergus merganser of ornithologists, not only occurs in some numbers in British waters as a winter visitor, but breeds sparingly within our limits, it has some claim to be included in the present volume, although it cannot be regarded as a very striking feature in coast bird life. It is also far less exclusively marine than the preceding species. The Goosander is an even more handsome bird than the Red-breasted Merganser, and is the largest species in the present sub-family. The colours of the male are arranged in a most effective and strongly-contrasted way. The head and neck are dark metallic-green, the breast is a delicate and beautiful pink, the upper parts and the wings are black and white, the under parts below the breast white. The female has the head reddish-brown, the upper parts grayish-brown or pale chestnut, the lower buffish-white. In its habits and in the haunts it frequents, the Goosander very closely resembles its smaller ally. When, in winter, frequenting the coast it delights in the bays and fjords, but occasionally wanders to less precipitous shores, notably estuaries and the mouths of tidal rivers. It is a remarkably agile bird in the water, swimming and diving with equal ease, but on the land its movements are ungainly, the bird wriggling along with its breast almost touching the ground, in a very Diver-like manner. In diving, it often descends to a great depth. Although not often seen much on shore, it possesses the Cormorant-like habit of basking on some rock jutting from the water, sitting with its body upright and wings half expanded. Its food consists of fish, crabs, molluscs, and aquatic insects. Most of this is obtained whilst the bird is diving.
