Formicariidae

Formicariidae, the antthrushes, is a family of small suboscine passerine birds of subtropical and tropical Central and South America, forest birds that specialize in feeding on insects at or near the ground. As currently defined the family comprises 12 species in two genera, Formicarius with six species and Chamaeza with six species, after molecular phylogenetic research found the family as previously delimited to be highly paraphyletic and led to the antpittas being reclassified into the separate families Grallariidae and Conopophagidae. Antthrushes are relatively small, 10 to 20 centimeters long, with long powerful legs that give them a distinctive upright posture and an essentially vestigial tail, mostly colored in shades of rusty brown, black and white. They lay two or three eggs in a nest in a tree, with both sexes incubating.
