Bradypterus

Bradypterus is a genus of small insectivorous songbirds ("warblers") in the newly recognized grass warbler family (Locustellidae). They were formerly placed in the Sylviidae, which at that time was a wastebin taxon for the warbler-like Sylvioidea. The range of this genus extends through the warm regions from Africa around the Indian Ocean and far into Asia.

The locustellid bush warblers are related to the grass warblers of Locustella and Megalurus, but share lifestyle and related adaptations and apomorphies with bush warblers in the family Cettiidae. These belong to an older lineage of Sylvioidea. Both "bush warbler" genera are smallish birds well adapted to climbing among shrubbery. They are markedly long-tailed birds, at first glance somewhat reminiscent of wrens.

These are quite terrestrial birds, which live in densely vegetated habitats like thick forest and reedbeds. The will walk away from disturbance rather than flush. The plumage similarities and skulking lifestyle makes these birds hard to see and identify.

Locustellid bush warblers tend towards greyish browns above and buffish or light grey tones below. They have little patterning apart from the ubiquitous supercilium. Altogether, they appear much like the plainer species among Acrocephalus marsh-warblers in coloration. Cettiid bush warblers tend to be somewhat more compact, with less pointed tails, but are otherwise very similar.

Species

This genus has been recently revised. The Sri Lanka bush warbler is sometimes placed in this genus but is now placed in its own monotypic genus (Elaphrornis). Several other former members of this genus (e.g. the Chinese bush warbler) are now placed in Locustella. Victorin's warbler is no longer a member of this genus or even the family Locustellidae, but is now placed in its own monotypic genus Cryptillas in the African warbler family Macrosphenidae.

The genus contains 12 species:[1]
