The Indian robin is sexually dimorphic in plumage with the male being mainly black with a white shoulder patch or stripe whose visible extent can vary with posture. The northern populations have the upper plumage brownish while the southern populations are black above. The males have chestnut undertail coverts and these are visible as the bird usually holds the 6–8 cm long tail raised upright. The females are brownish above, have no white shoulder stripe and are greyish below with the vent a paler shade of chestnut than the males. Birds of the northern populations are larger than those from southern India or Sri Lanka. Juvenile birds are much like females but the throat is mottled.
