Conservation Status

According to the Red List of the World Conservation Union (IUCN), three species are Critically Endangered, facing an extremely high risk of extinction; five are Endangered, facing a very high risk of extinction; seven are Vulnerable, facing a high risk of extinction; and eight are Near Threatened, in danger of becoming threatened with extinction. The U.S. Fish and Wildlife Service lists five endangered species: Bachman's warbler, Barbados yellow warbler, golden-cheeked warbler, Kirtland's warbler, and Semper's warbler. For the most part, a small breeding range and shrinking habitat are the primary threats to these species. When people undertake habitat-preservation efforts, however, the species generally respond favorably.
