Bachman’s Warblers

A recently extinct species, Bachman's warblers nested in the underbrush of forested swamps in the region bounded by Louisiana up to Kentucky and Maryland, and over to the Carolinas and Georgia, migrating to Cuba in winters. None have been seen since the early 1960s in North America and they were listed as endangered in 1967.

The last confirmed sightings were in 1988 and before that in 1961 in South Carolina. The Bachman's Warbler's last stronghold was in I'on Swamp, South Carolina. Habitat destruction was probably the main cause of its disappearance. Its extinction is not yet officially announced, because habitat remaining in Congaree National Park needs to be surveyed.

Furthermore, on January 14, 2002, a bird reminiscent of a female Bachman's Warbler was filmed at Guardalavaca, Cuba. As Vermivora warblers are not known to live more than about 7 years, if the identification is correct it would imply that a breeding population managed to survive undiscovered for decades. The female warbler incubates her eggs while father goes looking out for food.
