Vulnerable A common breeder on Gough Island only, where at least 20,000 pairs occur, but a small remnant population breeds also on Tristan da Cunha I., where the once-common species was one of the few sources of food for the islanders during winter, a reason for its near-extinction there. The Gough population is apparently stable, but the breeding on virtually a single island makes the species highly susceptible to introduced predators, oil-spills, or natural disasters.
