Conopophagidae
10 species
The gnateaters are a bird family, Conopophagidae, consisting of ten small passerine species in two genera, which occur in South and Central America. The family was formerly restricted to the gnateater genus Conopophaga; analysis of mtDNA cytochrome b and NADH dehydrogenase subunit 2 sequences (Rice 2005a,b) indicates that the "antpittas" of the genus Pittasoma also belong in this family. The association between this genus and Conopophaga is also supported by traits in their natural history, morphology, and vocalizations (Rice, 2005a). The members of this family are very closely related to the antbirds and less closely to the antpittas and tapaculos. Due to their remote and dim habitat, gnateaters are a little-studied and poorly known family of birds, though they are often sought after by birdwatchers.
Gnateaters are birds of the forest understory, bamboo stands, and the forest floor. The members of the genus Conopophaga are found in the Amazon and Orinoco basins, east and central Andean slopes, Atlantic Forest, and nearby regions, while the members of the genus Pittasoma are found in the Chocó, and Panama and Costa Rica. Some species live in impenetrable thickets; others live in more open forest. Most are entirely restricted to humid habitats, but several species extend into drier regions in eastern Brazil. While the members of the genus Conopophaga always are found near the forest floor, seldom rising more than 1.5 m above the ground, they also seldom travel or spend much time on the ground (though they do feed there; see diet). The members of the genus Pittasoma are more commonly seen hopping around on the ground.
