The purple sunbird (Cinnyris asiaticus) is a small bird in the sunbird family found mainly in South and Southeast Asia. In many parts of India it is quite common. Like other sunbirds they feed mainly on nectar, although they will also take insects, especially when feeding young. The males can appear all black in harsh sunlight but the purple iridescence is visible on closer observation or under good light conditions. Females are olive above and yellowish below.Compared to Purple-rumped sunbird, the purple sunbird is more alert and less friendly. They often fly away at the sight of people.
