Cassin's Auklet
Ptychoramphus aleuticus (Pallas, 1811)
Alcidae — Auks
Cassin's Auklet, Ptychoramphus aleuticus, is a seabird of the North Pacific coastal waters of North America and Middle America, breeding on offshore islands from the Aleutian Islands and south Alaska to northern Baja California. It nests in small burrows and is the only species in Ptychoramphus. The bird is a small auk with dark upperparts, paler underparts, a small white mark above the eye, a dark bill with a pale spot, and blue feet. It keeps much the same appearance through the year, and at sea its flight has been likened to a flying tennis ball.
