, ''poonensis'', from the nominate race which occupies most of the species' range. They describe ''poonensis'' as paler and browner above, with a deeper bill, and mostly pale lower mandible, a more mottled throat, breast and flanks (in fresh plumage), less contrastingly white "spectacles" and throat, and perhaps a more rounded wing.

Behaviour

Asian brown flycatcher is a common bird found in open woodland and cultivated areas. It nests in a hole in a tree, laying four eggs which are incubated by the female. The male Asian brown flycatcher sings a simple melodic song during courtship. This bird is parasitised by the chewing louse ''Philopterus davuricae.''

Vagrancy

The Asian brown flycatcher is an extremely rare vagrant to Western Europe. Records have come from Britain, Denmark, and Sweden, and in addition, there are unproven claims from Ireland, the Faroe Islands, and Norway.
