Range Description

Atlantisia rogersi is confined to the South Atlantic island of Inaccessible, Tristan da Cunha (St Helena to UK). The population has been variously estimated as 1,200 birds in 1938 (Hagen 1952), 5,000-10,000 birds in 1952 (Elliott 1957) and 1,000-2,000 breeding pairs in 1974 (Richardson 1984). The most accurate survey to date gave an estimate of 8,400 birds(Fraser et al. 1992). It is abundant on the island and may be at carrying capacity given its high population density, delayed maturity, small clutch-size, and lack of major predators or competitors (Fraser et al. 1992, Taylor and van Perlo 1998).
