The greatest variety of species is found in Africa, where the group probably arose. While hummingbirds hover to feed, sunbirds land and perch on flower stalks. Sunbirds are tropical nectar-sipping birds belonging to the family Nectariniidae. Sunbirds and spiderhunters make up the family Nectariniidae of passerine birds.

Sunbirds live in tropical forests, inland wetlands, savannas, and scrubland in Africa, southern Asia, the Middle East, and northern Australia. Males often have brilliant iridescent plumage, while females tend to be duller or different colors than males. There are a few negative interactions, for example the scarlet-chested sunbird is considered a pest in cocoa plantations as it spreads parasitic mistletoes.[3]. Although sunbirds are stunningly beautiful, they are not typically captured for the pet trade because of their specific nutritional needs.
