The Malagasy warblers are a newly validated clade of songbirds. They were formally named Bernieridae in 2010. The family consists of ten species of small forest birds and is endemic to Madagascar.

Several of these species are very poorly known and were described by science only very recently. Appert's Tetraka was only described in 1972 and the Cryptic Warbler in 1996. The Appert's Tetraka, along with the Dusky Tetraka are threatened by habitat loss, and are listed as vulnerable.

Unpublished research suggest that there are several cryptic species left to describe in the family.

Most Malagasy warblers live in the humid rainforests in the east of Madagascar, though a few species are found in the drier south west of the island. They feed on insects and will form mixed-species feeding flocks of up to six species while foraging.
