The snowy sheathbill (Chionis albus), also known as the greater sheathbill, pale-faced sheathbill, and paddy, is one of two species of sheathbill. It is usually found on the ground. It is the only land bird native to the Antarctic continent.
A snowy sheathbill is about 380–410 mm (15–16 in) long, with a wingspan of 760–800 mm (30–31 in). It is pure white except for its pink, warty face; its Latin name translates to "snow white".
The snowy sheathbill does not have webbed feet. It finds its food on the land. It is an omnivore, a scavenger, and a kleptoparasite. It steals krill and fish from penguins and sometimes eats their eggs and down-covered chicks. It also eats carrion, animal feces, and, where available, human waste. It has been known to eat tapeworms that have been living in a chinstrap penguin's intestine.
