Ant Thrushes: Formicariidae

In 2003, four species of antbirds were considered Critically Endangered, facing an extremely high risk of extinction, or dying out, in the wild. These were the fringe-backed fire-eye, the Rio de Janeiro antwren, the Alagoas antwren, and the Rondonia bushbird. Sixteen other species were considered Endangered, facing a very high risk of extinction, and eleven species were classified as Vulnerable, facing a high risk of extinction. The main reason these birds are at risk for extinction is loss of habitat due to human activities such as farming, mining, and development.
