The antbirds are a large passerine bird family, the Thamnophilidae. They are found in subtropical and tropical Central and South America, from Mexico to Argentina. There are more than 200 species called antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds.
They are related to the antthrushes and antpittas (family Formicariidae), the tapaculos, the gnateaters and the ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes.
Antbirds are generally small birds with rounded wings and strong legs. They have mostly dull grey, white, brown and rufous plumage. The two sexes have somewhat different pattern and colouring. Some species communicate warnings to rivals by exposing white feather patches on their backs or shoulders. Most have heavy bills, which in many species are hooked at the tip.
Most species live in forests, although a few are found in other habitats. They eat mostly insects and other arthropods. Small vertebrates are occasionally taken. Most species feed in the understory and midstory of the forest, although a few feed in the canopy and a few on the ground.
Antbirds are monogamous, mate for life, and defend territories. They usually lay two eggs in a nest. Both parents share the tasks of incubating eggs and raising the nestlings. After fledging, each parent cares exclusively for one chick.
