Nicobar sparrowhawk

The Nicobar sparrowhawk, Tachyspiza butleri, is a small bird of prey in the family Accipitridae that is found only in the Nicobar Islands of India. Two subspecies are recognised: the nominate form on Car Nicobar in the north of the archipelago, and Tachyspiza butleri obsoleta on Katchal and Camorta in the central islands. It measures about 28 to 34 centimetres in length with a wingspan of 50 to 57 centimetres. A museum specimen once attributed to this species from Great Nicobar was later found to be a misidentified Besra, so the species is not known from that island. It was formerly placed in the genus Accipiter and has since been moved to Tachyspiza. Its natural habitat is subtropical or tropical moist lowland forest, and it is threatened by the loss of that habitat.
