The sunbirds and spiderhunters make up a family, Nectariniidae, of passerine birds.

They are small, slender passerines from the Old World, with long, usually decurved bills; some species have long tail; many are brightly coloured, most with some iridescence, particularly in the male. They live from Africa to Australia, across Madagascar, Egypt, Iran, Yemen, southern China, the Indian subcontinent, the Indochinese peninsulas, the Philippines, southeast Asia to the nearby Pacific islands, just reaching northern Australia. The number of species is greater in equatorial and tropical areas.
