Grey petrel  (Procellaria cinerea)

A circumpolar sub-Antarctic species (6) that breeds on islands in the Pacific, Atlantic and Indian Oceans (7). These include Gough Island and the Tristan da Cunha group (St Helena, UK), Prince Edward and Marion islands (South Africa), Crozet, Kerguelen and Amsterdam islands (French Southern Territories), and Campbell and the Antipodes islands (New Zealand) (3). The bird is thought to be extinct on Macquarie Island (Australia) since the 1960s, although there have been recent attempts to recolonise (3). Gough and Antipodes are believed to support the bulk of the current population (3).

The grey petrel is pelagic, returning to nesting islands and coastal cliffs only to breed (1) (3).
