Snowy Sheathbill--Anvers Island

This image is of a snowy sheathbill at Anvers Island, Antarctica. Snowy sheathbills are scavengers, acquiring much of their nourishment by stealing food already caught by penguins and shags or by eating human refuse. For this reason, they frequently live close to gentoo and chinstrap penguin or shag colonies. They primarily live around the northern tip of the Antarctic Peninsula. Sheathbills can grow to 40 centimeters (16 inches) in length with a wingspan of 79 centimeters (31 inches).
