3a. The list has comprehensive items and annotations. 3b. The list is well-sourced to reliable sources, and the UPSD tool isn't indicating any actual problems (but this isn't a source review). 3c. The list meets requirements as a stand-alone list, it isn't a content fork, it doesn't largely duplicate another article (that I can find), and it ...
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.
Sunbirds are generally small birds with long, thin, down-curved bills and brightly coloured, iridescent plumages. [2] They display marked sexual dimorphism, and males are much more visually striking than females, who are usually dull green, brown, or grey. The spiderhunters (Arachnothera) are larger than other sunbirds and show less sexual ...
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 ...
Cyanomitra is a genus of African sunbirds. Its members are sometimes included in Nectarinia. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings.

The collared sunbird is a common breeder across most of sub-Saharan Africa. Two or three eggs are laid in a suspended nest in a tree. It is a seasonal bird migrant within its range. Collared sunbirds are tiny, only 9–10 cm (3.5–3.9 in) long. They have short thin down-curved bills and brush-tipped tubular tongues, both adaptations to nectar ...
