Sunbirds are the old-world equivalent of hummingbirds and there area a great number of species of them across Asia, Australasia, the Middle East and Africa. The Olive-backed Sunbird is the only one in Australia (it also occurs in China, the Philippines and Malaysia), where it lives in the tropical north. It is a very small bird, at a maximum of 12 cm, and feeds on nectar from flowers. Both sexes have yellow underparts with an olive back and a long, curved black bill. The male also has an iridescent black throat. This particular bird is on the species' distinctive nest, which hangs from tree branches.
