Antarctic petrels breed in the IBA

Important Bird Area

Stewart Buttress is part of the 665 ha Coalseam Cliffs and Mount Faraway Important Bird Area (IBA), designated as such by BirdLife International because it supports a colony of about 10,000 breeding pairs of Antarctic petrels. The birds nest in a scree-filled hollow between two 60 m high dolerite cliffs. Other birds recorded as breeding in the vicinity include snow petrels and south polar skuas.[1]
