Sunbird drinking nectar from typical bird-pollinated flower. As nectar is a primary food source for sunbirds, they are important pollinators in African ecosystems. Sunbird-pollinated flowers are typically long, tubular, and red-to-orange in colour, showing convergent evolution with many hummingbird-pollinated flowers in the Americas. [10]

They vary from the other sunbirds in the nature of their nest, which is suspended underneath a large leaf, usually a banana leaf but sometimes a palm frond or even a branch. The style of nest can be quite variable, a simple cup in the case of the streaked spiderhunter , an elongated tube for the yellow-eared spiderhunter and a bottle shape for ...
Nectarivorous – those who feed on flower nectar (e.g. hummingbirds, sunbirds) Folivorous – those who feed on leaves, petals and other plant material ( turacos , mousebirds ) This sixth diet type is usually in association with one of the above, as very few birds are solely folivorous.
The name Hedydipna comes from the Greek hēdudeipnos, meaning "dainty-supping" or "sweet-eating" — a reference to the nectar sipping habits of these species. [3] These sunbirds are largely restricted to Africa and western islands in the Indian Ocean, though the Nile Valley sunbird is found as far east as Yemen.
