Lesser Coucal

The lesser coucal is a cuckoo of marshy land with grass and tree cover, with a wide range that overlaps with several similar species. It is separated by its smaller size, less prominent bill, pale shaft streaks on the head and back feathers, a much longer claw on the hind toe and a distinct call. It is one of the few coucals with seasonal plumage differences, but the sexes cannot be told apart in the field. Six subspecies are recognised (Wikipedia, general species account).
