Camptostoma is a genus of birds in the tyrant flycatcher family Tyrannidae.

Extant species

The genus contains two species.[2]

Image Scientific name Common Name Distribution
Camptostoma imberbe Northern beardless tyrannulet southeasternmost Arizona and Texas of the United States through Mexico and Central America to northwestern Costa Rica
Camptostoma obsoletum Southern beardless tyrannulet Costa Rica through South America south to Paraguay, Bolivia, and Argentina.

These are very small passerine birds which breed in the tropical and subtropical Americas from the southernmost USA south to Paraguay, Bolivia, and Argentina. The two species are similar, and were once considered conspecific. However, they overlap without interbreeding in central Costa Rica.

These are species of light forests, cultivation and gardens with trees. The domed nest is made of plant fibre or leaves with a side entrance.

They are active birds, feeding in a vireo or warbler-like fashion on insects, spiders and berries.
