"The care which the mother takes of her young," says Audubon, "cannot be exceeded. She leads them gently in a close flock in shallow waters, where, by diving, they procure food, and at times, when the young are fatigued and at some distance from the shore, she sinks her body in the water and receives them on her back, where they remain several minutes. At the approach of their merciless enemy, the Black-backed Gull, the mother beats the water with her wings, as if intending to raise the spray around her, and, on her uttering a peculiar sound, the young dive in all directions, while she endeavours to entice the marauder to follow her, by feigning lameness, or she leaps out of the water and attacks her enemy, often so vigorously that, exhausted and disappointed, he is glad to fly off, on which she alights near the rocks, among which she expects to find her brood, and calls them to her side. Now and then I saw two females which had formed an attachment for each other, as if for the purpose of more effectually contributing to the safety of their young, and it was very seldom that I saw these prudent mothers assailed by the Gulls." We must not omit to mention that the eagerness of these birds for brooding is so great, that, when robbed of their eggs, they have frequently been known to steal the eggs or even the young of others of their species. In its natural state the Eider Duck subsists upon small fish, molluscs, crustaceans, and fish spawn, but when kept confined will eat grain. The flight of this species, which is steady and rapid, is usually carried on near the surface of the water; it dives with facility, and is capable of remaining submerged for a considerable time. THE KING EIDER. The KING EIDER (_Somateria spectabilis_) has the bill, the sides of which are elevated, arched and ridged, surrounded by a fine black band; a similar band runs from the base of the under mandible down each side of the neck. The upper head is grey, the cheeks are sea-green, the neck, back, and sides of the rump white, the front of the breast is light flesh-red; the scapulars, lower part of back, wings, tail, and belly, are white, and the rest of the feathers black; tertials, as in the preceding species, deflected. The eye is brown, beak red, and foot reddish. The female is distinguishable from that of the True Eider by her light reddish brown plumage, and by the structure of the base of the bill.
