Physical Description: This species is 13 cm (5.1 in) long, including the cocked tail. It is similar in shape to the larger spotted flycatcher but relatively longer-tailed. The dark bill is relatively large and broad-based. The adult has grey-brown upperparts, which become greyer as the plumage ages, and whitish underparts with brown-tinged flanks. Young birds have scaly brown upperparts, head, and breast.
Geographical Variation: Although usually treated as monotypic, populations in the Indian subcontinent and the Andaman Islands should be regarded as a separate subspecies, poonensis. This subspecies is paler and browner above, with a deeper bill, 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.
Behavior: 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.
Vagrancy: The Asian Brown Flycatcher is an extremely rare vagrant to Western Europe. Records have come from Britain, Denmark, and Sweden, and there are unproven claims from Ireland, Faeroe, and Norway.
