The olive-backed sunbird (Cinnyris jugularis), also known as the yellow-bellied sunbird, is a species of sunbird found from Southern Asia to Australia.They are small songbirds, at most 12 cm (4.7 in) long. In most subspecies, the underparts of both male and female are bright yellow, the backs are a dull brown colour. The forehead, throat and upper breast of the adult male is a dark, metallic blue-black.

Took this picture of the bird just outside my window at close range. It was quite difficult to photograph them as they do not keep still !
