Cinnyris venustus (Variable sunbird)

Synonyms: Nectarinia venusta

Wikipedia Abstract

The variable sunbird (or yellow-bellied sunbird), Cinnyris venustus (formerly Nectarinia venusta), is a sunbird. The sunbirds are a group of small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed most of the time. Variable sunbirds are small, only 10 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations to their nectar feeding.
