Everything about Sunbird totally explained

The sunbirds and spiderhunters are very small passerine birds which feed largely on nectar, although that'll also take insects, especially when feeding young. Flight is fast and direct on their short wings.
   The sunbirds find 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.
   The sunbirds are tropical species, with representatives from Africa to Australasia; the greatest variety of species is in Africa, where the group probably arose. Most species are sedentary or short-distance seasonal migrants.
   Like the hummingbirds, they're strongly sexually dimorphic, with the males usually brilliantly plumaged in metallic colours. Sunbirds have long thin down-curved bills and brush-tipped tubular tongues, both adaptations to their nectar feeding. Up to three eggs are laid in a purse-shaped suspended nest.
