Indian Robin
Copsychus fulicatus
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.

Madagascar Magpie-Robin
Copsychus albospecularis
The Madagascar magpie-robin is around 18 cm (7 in) in length and weighs 21 to 24 g (0.74–0.85 oz). The plumage varies by sex; the male of the nominate subspecies has all-black plumage with a white shoulder patch and the female has a grey-brown crown, back and tail, grey-breast and throat and rufous wings and rump. The males of the other two subspecies have more white of the wings and a white abdomen; the female of C. a. pica is much paler overall.
