Nectarinia osea (Nectarinia osea)

The sunbirds and spiderhunters are very small 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.
The sunbirds have counterparts in two very distantly related groups: the hummingbirds of the Americas and the honeyeaters of Australia. The resemblances are due to convergent evolution due to the similar nectar-feeding lifestyle. Most sunbird species can take nectar by hovering like a hummingbird, but usually perch to feed.
