The purple sunbird (Cinnyris asiaticus) is a small sunbird. Like other sunbirds they feed mainly on nectar, although they will also take insects, especially when feeding young. They have a fast and direct flight and can take nectar by hovering like a hummingbird but often perch at the base of flowers - however, they are not related to hummingbirds. The adult breeding male has a plumage that may appear all black (particular in low light) or dark metallic blue or purplish-black - depending on the light conditions. Females are yellow-grey to olive brown above and yellowish below. The purple sunbird is found in India and Sri Lanka.
