Biogeographically, Christmas Island is an oceanic island, with breeding and visiting species originating from several sources including South-East Asia, Australia, the Palaearctic, pelagic, and other undetermined sources. The Island has a high degree of endemism and this is expressed in the avifauna through 11 endemic taxa among the 23 breeding species. One hundred and forty-nine species of birds have been recorded from the Island, of which 14 are breeding landbirds, nine are breeding seabirds, 18 are visitors and 108 are vagrant species. It also includes reviews of the history of the Island’s ornithology, its avian biogeography, the taxonomy of selected endemic taxa, population estimates of resident species, and current and past threats to its birds.
