Essential Snowy Sheathbill Information
The snowy sheathbill, also known as the pale-faced sheathbill, is the only native land bird of Antarctica. Found in Antarctica, South Georgia, and the South Orkney Islands, it is a curious and opportunistic scavenger, often spotted at penguin nesting sites (rookeries) where it takes advantage of any food source it can find.
Physical Characteristics
The snowy sheathbill measures about 38 cm (15 inches) in length and is primarily white, with a pale-pink face and a darker beak. Unique to its appearance are the irregular, warty growths between its eyes and beak. Unlike most Antarctic birds, snowy sheathbills don’t have webbed feet, which gives them extra dexterity and allows them to scavenge and move around easily.
Behavior and Diet
Sheathbills are known for their eclectic diet, consuming almost anything they can find. This includes stealing regurgitated fish intended for penguin chicks, as well as penguin eggs and even unattended chicks. They are consummate survivors, also eating carrion, animal droppings, and even human waste if accessible.
Habitat and Interaction
Despite being considered a land bird, the snowy sheathbill is ancestrally related to seabirds, much like gulls. They are curious creatures, often approaching closely and even landing on Zodiacs, kayaks, or sometimes people. However, their habit of frequent guano deposits makes them less welcome on personal items!
