Part 45

The young brood take to the water immediately on being hatched. To effect this they are often obliged to travel a considerable distance, and if difficulties present themselves, insurmountable in any other way, the parent bird carries the young in her bill. Once clear of the rocks, they are liable to no further molestation from land robbers. But the sea is not without its dangers, for the rapacious Black-backed Gull frequently attacks them, and, but for the self-devotion and bravery of the mother bird, would commit great havoc among them. At his appearance the young dive in all directions, while the mother counterfeits lameness to distract his attention from them to herself, or springs from the water and attacks the Gull until he is compelled to retire from the contest.

THE BLACK (OR COMMON) SCOTER OEDEMIA NIGRA

General plumage deep black; quills dusky brown on the inner web, glossy grey beneath; disk of the upper mandible orange-yellow; protuberance at the base black; no speculum on the wings. Female--general plumage brown of several shades; bill without the protuberance; nostrils, and a spot towards the tip, yellowish. Length eighteen inches. Eggs pale buff.

This bird is well known along the eastern coast of England under the name of Black Duck. Although a few scattered specimens have been observed from time to time during summer, in most parts it must be considered as a winter visitant only. Being the only entirely black Duck which frequents our shores, it is distinguished among other species by its colour alone. Small parties of these birds may occasionally be seen on different parts of the coast, swimming and diving at a short distance outside the surf, or flying, three or four together, at an elevation of a few feet above the surface of the sea. Large flocks visit the sea between us and Holland at times. They fly rapidly in a straight line, and when diving remain a long time under water. Their food consists of mussels and other shellfish, in quest of which they often ascend the creeks and arms of the sea, but they are rarely seen in fresh water.

The flesh of the Black Duck is said to be oily and fishy; on this account it is in some Roman Catholic countries classed with fish, and allowed to be eaten during Lent. In some parts of the Continent, where it is consequently in demand, fishermen take advantage of its diving propensities, and spread their nets over the mussel banks to which they have observed that these birds resort, and capture them in large numbers. The nest of the Scoter is described as being like that of the Eider Duck, and similarly located. The female also covers her eggs with down from her own breast, but in smaller quantities. A few of this species remain to breed in the north of Scotland.

THE VELVET SCOTER OEDEMIA FÚSCA

General plumage velvet black; below the eyes a white crescent; speculum white; bill orange, protuberance at the base, nostrils and edge of mandibles, black; irides and feet red, the membranes of the latter black. Female smaller; upper plumage sooty brown; under parts light grey, streaked and spotted with dusky brown; between the bill and eye a whitish spot, and another over the ear; bill dusky ash; irides brown; feet dull red. Length twenty-three inches. Eggs buff.

The Velvet Scoter, an inhabitant of the extreme northern regions of Asia and Europe, appears in the British Isles as a winter visitor only, being sometimes seen on the eastern coast of Scotland, in large flocks, but not generally extending its migration to our southern shores except in the severest weather. It may be distinguished from the Common Scoter by its larger size, and yet more strikingly by the conspicuous white bar across the wing.

The habits and food of the Velvet Duck differ in no material respect from those of the Common Scoter, or Black Duck.

THE SURF SCOTER OEDEMIA PERSPICILLATA

A bony protuberance on each side of the bill near the base; no speculum; general plumage black; on the forehead and nape a patch of white; bill yellow, with a square black spot on each side near the base; irides white; feet red, the membranes black. In the female the black is replaced by dark ash-brown, and the white by light grey; bill dark olive; feet brown, with black membranes. Length twenty inches. Eggs white.

Only a few specimens of this bird have been obtained in Europe, and these probably had been driven eastward by storms from North America, where alone they are found in any numbers. In habits and food the Surf Scoter resembles the common species, deriving its name from the pertinacity with which it selects, as its feeding-ground, a sandy beach over which surf rolls. It rarely or never visits the salt marshes.

THE GOOSANDER MERGUS MERGANSER

Head and crest greenish black; back black; speculum (not barred with black), under parts, wing-coverts, outer scapulars, and some of the quills, buff; bill red, the ridge and nail black; feet vermilion. Length twenty-four to twenty-eight inches. Female and young--head and crest reddish brown; breast and flanks pale buff; upper plumage dark ash; bill and feet dull red. Eggs dull white.

The Goosander is a regular winter visitor to the shores of Great Britain and Ireland, frequenting bays and estuaries, but preferring fresh-water rivers and lakes, where it makes great havoc among trout and other fish. It is far more abundant in the north than in the south, and, according to Macgillivray, is sometimes seen even in summer in the Scotch lochs. It has been known to breed in the outer Hebrides, and of late years in several parts of the Highlands, but the general summer residence of this species is much farther to the north, both in the eastern and western hemispheres. The habits of the Goosander and Merganser are so much alike that further detail is unnecessary.

The females and young birds of the Goosander and Merganser are popularly called Dun-divers.

THE RED-BREASTED MERGANSER MERGUS SERRATOR

Head, crest, and neck black, with greenish reflections; a white collar round the neck; breast reddish brown, spotted with black; near the insertion of the wing several white spots, edged with black; speculum white, divided by two transverse black bars; back black; belly white, barred on the flanks and rump with wavy grey lines; bill and irides red; feet orange. Length twenty-two inches. Female smaller; head and crest reddish brown; breast mottled with ash and white; upper plumage and flanks deep ash-colour; speculum with one black bar; bill and feet dull orange; irides brown. Eggs whitish ash.

This large and handsome bird is not uncommon in the estuaries and rivers of Great Britain, but is most frequent in the north. It is resident in Scotland and Ireland. The adult male is less frequently seen than females and young males, which closely resemble one another in size and plumage, both being inferior to the first in brilliancy of colouring. Their food consists of fish, especially sand-eels, and, when they find their way into fresh-water lakes and rivers, of eels and trout, which they capture by diving, and retain with ease by the help of their strong bills notched throughout like a saw.

In birds of the first year the tuft of feathers on the head is barely perceptible, and there is but a slight tinge of red on the lower part of the neck. Most of the Mergansers which resort to our shores during winter visit us from high latitudes; but a few remain to breed in the Scotch and Irish lakes, making their nests of dry herbage and moss mixed with down from their own breasts.

The name Merganser, that is, 'Diving Goose', has reference to the size of the bird and its habit of diving for its food. Its flight is strong and rapid, but differs somewhat from that of the Ducks, the neck being not stretched out to its full length, but slightly folded back. After the young are hatched the male deserts the female and leaves her to bring off her brood without assistance.

THE SMEW MERGUS ALBELLUS

Crest, neck, scapulars, smaller wing-coverts, and all the under parts white; cheeks and back of the head greenish black; two crescent-shaped marks advancing from the shoulders on each side to the breast black; tail ash coloured; bill and feet bluish grey, the membranes black; irides brown. Length seventeen inches. Female smaller; head and cheeks reddish brown; under parts white, clouded on the breast, flanks, and rump, with ash-grey; upper plumage and tail greyish black; wings variegated with black, white, and grey. Eggs whitish.

The birds of this genus, though placed among the Anatidæ, or Duck tribe, are so strongly marked by the conformation of the bill that a simple examination of the head alone will enable the student to distinguish either of the species from the true Ducks already described. On the coast of Norfolk the popular name 'Smee Duck' includes several kinds of Ducks, and I presume the present species; but the bill, in the form of an elongated and almost cylindrical cone, with the edges of both mandibles furnished with saw-like teeth pointed backwards, cannot fail to distinguish the genus Mergus.

The Smew, or Smee, properly so called, is a winter visitor with us, more impatient of cold than the Duck-tribe generally, and consequently frequenting the southern more than the northern parts of the island. In open weather it resorts to our rivers and fresh-water lakes, where it feeds on small fish and other aquatic animals, which it obtains by diving. In severe frosts it either flies farther south or repairs to tidal rivers and harbours. Though not a rare bird, it is sparingly distributed. It is found on many of the continental rivers, even those which are far distant from the sea, but is not often killed, as it is shy of being approached, readily takes wing, flies swiftly, and as a diver is most rapid and expert. It is, however, little sought after, for, in spite of its relationship, its strong fishy flavour prevents it from passing muster as a Duck. Of its nesting little or nothing is known. In the north of Devon it is called, according to Montagu, 'Vare Wigeon', from the supposed resemblance of its head to that of a 'vare' or weasel. I have also heard it called the 'Weasel Duck' in Norfolk, and on the south coast the 'Weasel-headed'.
