9. Gavia arctica. 28 inches.

This loon lives in the Arctic regions and only rarely is found, in winter, in Northern United States. In summer, it can readily be distinguished from the common loon by the gray crown and hind-neck, as well as by different arrangement of the black and white markings. In winter, they are quite similar to the last species but can be recognized by their smaller size, and can be distinguished from the winter plumaged Red-throated Loon by the absence of any white markings on the back. Like the grebes, loons have to run over the surface of the water in order to take flight, and they are practically helpless when on land. Their flight is very rapid, in a straight line, and their neck is carried at full length in front. This species has red eyes, as do all the other loons.

Nest. - The same as the last species, but the two eggs have more of an olive tint and are smaller (3.10 x2.00).

Range. - Arctic America, wintering in Canada and occasionally in Northern United States.
