180. Olor columbianus. 54 in.

Nostril situated at a greater distance from the eye than it is from the end of the bill; a small yellow spot on the bare space in front of the eye; plumage entirely white; bill and legs black. This is the swan that is found on the Atlantic coast, and is most abundant in the Miss. Valley. It is rare north of Chesapeake Bay, but it is abundant from there southward, in winter. They make a beautiful sight against the blue sky, their immense white wings slowly fanning the air and their long necks extended.

Notes. - A peculiar, flageolet-like "Who, who, who." (Elliott).

Nest. - A mass of weeds, grass and feathers on the ground; 3 to 6 greenish buff eggs (4.00 x 2.75).

Range. - Breeds within the Arctic Circle; winters south to the Gulf of Mexico; rare north of Va. on the Atlantic.
