The U.S. Fish and Wildlife Service will remove 21 species from the nation's endangered species list because they are considered extinct, but the much-debated ivory-billed woodpecker won a temporary reprieve, the agency announced Monday.

The list also includes the Bachman's warbler, once found in the Southeast. Controversy lingers, however, about the ivory-billed woodpecker. Many ornithologists remain unconvinced it survives, but others believe the bird is still found in remote swamps between Arkansas and Mississippi. Read more at the link in our bio.
