Lesser Coucal
Centropus bengalensis
This slightly smaller-sized and shorter-billed coucal has a very long hind claw, the longest within the genus. The overall plumage, as in many other coucals, is of a blackish bird with a long tail and rufous wings. They have two plumages, a breeding plumage in which the head and upper back are glossy with dark shafts to the feather and a duller non-breeding plumage in which the feather shafts on the head and back are whitish. The wing coverts also have pale shafts showing as whitish streaks on the brown feathers. The central upper tail coverts are barred and very long.
