Crimson Sunbird

The crimson sunbird is a tiny sunbird, only about 11 cm long, that feeds largely on nectar and also takes insects, especially when feeding its young. The adult male has a crimson breast, maroon back, black malar stripes, yellow rump and olive belly, and in most of the range a long green-blue tail; the female has an olive-green back and yellowish breast.

It has a medium-length thin, down-curved bill and a brush-tipped tubular tongue for nectar feeding, usually perching to feed though able to hover. Flight is fast and direct on short wings. Two or three eggs are laid in a suspended nest in a tree, and the call is chee-cheewee. (Wikipedia, general species account)
