Abstract
Threatened birds are best identified on the basis of specific objective criteria, such as those employed by the International Union for Conservation of Nature. By those criteria, approximately 13% of the world's avifauna is at immediate risk of extinction, and altogether 22% of species give cause for concern. These species occur disproportionately on islands and on the mainland of South America. Habitat loss is the most frequent threat to threatened birds; but numerous additional factors, including alien species and hunting, are implicated in the decline of many bird populations. Conservation actions include site and habitat protection; prohibitions on persecution and trade; and intensive, multifaceted management programs.
