Atlantic petrel  (Pterodroma incerta)

The Atlantic petrel is a seabird predominantly restricted to the South Atlantic, ranging from the east coast of South America to the west coast of Africa (2). Until recently, a breeding population existed on Tristan da Cunha, but this is now believed to be extinct. Today, Gough Island is the only location where this species still breeds, with an estimated population of around 1.8 million pairs (2).

This bird nests in colonies on islands, but is otherwise pelagic (2). Nesting occurs in burrows dug in peaty soils in fern-bush vegetation from 50 to 300 metres above sea level on Gough, and at higher elevations on Tristan (2).
