13. Fratercula arctica. 13 inches.

Puffins are grotesque birds, with short legs, stout bodies and very large, thin bills, that of the common Puffin being 2 in. in length and about the same in height; the bill is highly colored with red and yellow, and the feet are red; eyes, white. It will be noticed that the blackish band across the throat does not touch the chin, this distinguishing it from the Horned Puffin of the Pacific coast. Adults in winter shed the greater portion of their bill, lose the little horns that project over the eye, and the face is blackish; they then resemble young birds. They live on rocky shores, the more precipitous the better. They stand erect upon their feet and walk with ease.

Notes. - A low croak.

Nest. - They breed in large colonies on rocky cliffs, laying their single white eggs (2.50 x1.75) in crevices.

Range. - Breeds from Matinicus Rock, Me., northward; winters south casually to Cape Cod. Large-billed Puffin (F. a. naumanni) is found in the Arctic Ocean.
