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 the only land bird (excluding Penguins) native to Antarctica.^[3]

Description

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".^[4]

Range

The snowy sheathbill lives in Antarctica, the Scotia Arc, the South Orkneys, and South Georgia. Snowy sheathbills living very far south migrate north in winter.^[3]

Feeding

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.^[4]
