Herring Gulls, which are usually the most numerous birds in such places, are white with light, blue-grey backs and black outer wing feathers. Immature birds are dark greyish brown. Flocks of Old Squaw ducks, a long-tailed species which summers in the Arctic, may be seen swimming and diving in the icy water. The males are conspicuous with their white heads and necks marked with a dusky spot on each side. The females are less strikingly marked, but are usually associated with the males. Two other species of ducks may be noted quite commonly, the Merganser and the Golden-eye. The general colouration of the males of these two species may appear very similar at a distance, both being patterned with black and white, but the Merganser's dark head is unmarked and his bill is narrow, while the Golden-eye has a _ rounded white spot at the base of his typical broad duck bill on both sides of his proportionately large head. The females of these species, although both coloured with grey and brown, are not likely to be confused. L. L. S. Aids to Bird Study. "Birds of Eastern Canada", by P. A.
