In the Arctic regions, in Iceland, and on the rocky coasts of Norway and Sweden, Eider Ducks are very numerous. In Labrador, Audubon informs us, they begin to form their nests about the end of May or the beginning of June. 'For this purpose some resort to islands scantily furnished with grass; others choose a site beneath the spreading boughs of stunted firs, and, in such places, five, six, or even eight are sometimes found beneath a single bush; many are placed on the sheltered shelvings of rocks a few feet above high-water mark. The nest, which is sunk as much as possible into the ground, is formed of sea-weeds, mosses, and dried twigs, so matted and interlaced as to give an appearance of neatness to the central cavity, which rarely exceeds seven inches in diameter. In the beginning of June the eggs are deposited, the male attending upon the female the whole time. The eggs, which are regularly placed on the moss and weeds of the nest without any down, are generally from five to seven. When the full complement of eggs has been laid the female begins to pluck some down from the lower part of the body; this operation is daily continued for some time, until the roots of the feathers, as far forward as she can reach, are quite bare. This down she disposes beneath and around the eggs. When she leaves the nest to go in search of food, she places it over her eggs to keep up their warmth.'

Sir W. J. Hooker, in his interesting Journal of a Tour in Iceland, describes the nests as he saw them in the little island of Akaroe, where, as on other uninhabited islands, the Eider Ducks breed in great numbers. "On our landing on the rocky island, we found the Eider fowls sitting upon their nests, which were rudely formed of their own down, generally among the old and half-decayed sea-weed, that the storms had cast high up on the beach, but sometimes only among the bare rocks. It was difficult to make these birds leave their nests, and so little inclined were many of them to do it, that they even permitted us to handle them, whilst they were sitting, without their appearing to be at all alarmed. Under each of them were two or four eggs; the latter is the number they lay, but from many of them two had been taken for food by the natives, who prefer those which have young ones in them. June 24th." A few days later (June 27,) he visited the island of Vidöe, the residence of the ex-governor, where, he says, 'we were shown the immense number of Eider Ducks which lived on Vidöe, and which were now sitting on eggs or young ones, exhibiting a most interesting scene. The ex-governor made us go and coax some of the old birds, who did not on that account disturb themselves. Almost every little hollow place between the rocks is occupied with the nests of these birds, which are so numerous that we were obliged to walk with the greatest caution, to avoid trampling upon them; but, besides this, the ex-governor has a number of holes cut in the smooth and sloping side of a hill in two rows, and in every one of these, also, there is a nest. No Norfolk housewife is half so solicitous after her poultry as the ex-governor after his Eider Ducks, which by their down and eggs afford him a considerable revenue; since the former sells for three rix-dollars (twelve shillings) a pound. Cats and dogs are, at this season of the year, all banished from the island, so that nothing may disturb these birds.' I need scarcely add that the Eider down of commerce is taken from these nests, not in a pure state but mixed with fragments of plants. Pennant says that if the nest and eggs be taken 'the Duck lays again, and repeats the plucking of her breast, if she is robbed after that, she will still lay, but the drakes must supply the down, as her stock is now exhausted; if her eggs are taken a third time, she wholly deserts the place. The quantity of down found in one nest weighs about three-quarters of an ounce, and may be compressed into a ball two inches in diameter, but on being shaken out will fill a large hat.

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
ŒDEMIA 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.
