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. The
males appear all black except in some lighting when the purple
iridescence becomes visible. Females are olive above and yellowish
below.
In indonesia it is called also with Kolibri Ninja (Konin) and has lots of competing classes, lots of bird-keepers both beginners as well as experts in caring for birds already.
