Wagler, Syst. Av. Note to Art. Gracula (1827). Type, C. saularis.
The genus Copsychus contains in India a single species of Robin which is one of our best-known birds over the widest of ranges, known to all Europeans as the Dayal or Magpie-Robin.
The tarsus is stout and non-scutellated; the bill stout and straight and equal to rather more than half the head in length ; the rictal bristles are well developed ; the tail is almost equal in length to the wing, a feature which distinguishes it from all other genera in this subfamily.
The sexes have the same pattern in colour, but the black of the male is replaced by greys and browns in the females.
