The common babbler (Argya caudata ) is a member of the family of Leiothrichidae. They are found in dry open scrub country mainly in India. Two populations are recognized as subspecies and the populations to the west of the Indus river system are now usually treated as a separate species, the Afghan babbler (Turdoides huttoni ). The species is distinctly long-tailed, slim with an overall brown or greyish colour, streaked on the upper plumage and having a distinctive whitish throat.
This small, slim babbler with a long tail is buff to grey above with dark streaks. The underside is unstreaked and paler, the throat being nearly whitish.
The species was originally described as Crateropus caudatus before it was moved to the genus Argya and still later to Turdoides. The species ending was, however, retained in these new combinations but the corrected feminine form caudata matches the Latin gender of the genus Turdoides.
The common babbler group includes eclipes (Hume, 1877) from northern Pakistan to northwestern India and nominate caudata ( Dumont de Sainte Croix, 1823) in southern Pakistan, Nepal, Bangladesh and India (including the Lakshadweep Islands).
