This is a male olive-backed sunbird (Cinnyris jugularis), also known as the yellow-bellied sunbird. 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 as seen here. This picture was just taken outside my room window and it was quite difficult to picture them as they can't keep still due to their fast flight with their short wings. They take the nectar from this golden penda tree by hovering and classified as passerine birds which feed largely on nectar. It has been raining here for the past few days and you could see the droplets of rainwater on the leaves, flower and even on this tiny little bird ! I especially like the colour of the bird. Amazing to see nature's wonder !
