Asian fairy-bluebird- Male

The iris is crimson and eyelids pinkish; the bill, legs and claws are black, and mouth a flesh- colour. Marked sexual dimorphism is evident. The male is a shining ultramarine-blue with lilac reflections on its upper plumage, lesser wing coverts, and under tail coverts, while the sides of its head and the whole lower plumage are deep black; greater wing-coverts, quills, and tail black, and some of the coverts tipped with blue, and the middle tail-feathers glossed with blue.
