This species of bird is in the family Muscicapidae. It is found in the eastern Himalayas, from Nepal to Bangladesh. It winters in the northern Malay Peninsula.

Their lores, cheeks, and some of the ear-coverts are jet black, contrasting with a deep blue cap on their head and dark blue feathers on the wings and tail with a subtle purplish tinge. Males display a vibrant orange-rufous throat and chin, which extends to the rear flanks and mid-belly, with the lower underparts being whitish. The bill is black, and the legs vary in color from pale flesh-pink to pale pinkish gray or light horn-brown.

Their facial features include a pale buffish eyeing and lores, with dark brown cheeks and a pale rufous-tinged buff chin and throat. The remainder... Wikipedia →
