Horned Puffin (Fratercula corniculata) is an auk, similar in appearance to the Atlantic Puffin; this bird's bill is yellow at the base and red at the tip. It is a pelagic seabird that feeds primarily by diving for fish. It nests in colonies, often with other auks. The yellow bill plate grows before the breeding season and is shed later. They have a small fleshy black "horn" above their eyes. They have a white face with a dark line extending from the back of the eye and red feet.
