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.
The exact delineation of sunbird species is somewhat contested and varies from authority to authority: the International Ornithologists' Union (IOU) recognizes 146 species of sunbirds in 16 genera, [1] while other authorities recognise 143–147 species. [4] [5] The largest genera are Cinnyris and Aethopyga, with 53 and 23 species, respectively ...
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.
Leptocoma is a genus of sunbirds found from tropical South Asia to Papua New Guinea. 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 ornate sunbird is 10–11.4 cm (3.9–4.5 in) in length. The male weighs 6.7–11.9 g (0.24–0.42 oz), the female 6–10 g (0.21–0.35 oz). The species is sexual dimorphic. The male of the nominate subspecies is olive above, the remiges are black with green edging and the black tail has a white tip. The throat, side of neck, throat and ...
