Sunbird Chicks - Amazing 12 Days Journey From Nest To Sky 🎧

The sunbirds and spiderhunters make up a family, Nectariniidae, of passerine birds. They are small, slender passerines from the Old World, usually with downward-curved bills. Many are brightly coloured, often with iridescent feathers, particularly in the males. Many species also have especially long tail feathers. Their range extends from Africa to Australia, across Madagascar, Egypt, Iran, Yemen, southern China, the Indian subcontinent, the Indochinese peninsulas, the Philippines, Southeast Asia and the surrounding Pacific islands, and the uppermost part of northern Australia. The number of species is greater in equatorial and tropical regions. There are 132 species in 15 genera. Most sunbirds feed largely on nectar, but will also eat insects and spiders, especially when feeding their young. Flowers that prevent access to their nectar because of their shape (for example, very long and narrow flowers) are simply punctured at the base near the nectaries, from which the birds sip the nectar. Fruit is also part of the diet of some species. Their flight is fast and direct, thanks to their short wings. The sunbirds have counterparts in two very distantly related groups: the hummingbirds of the Americas and the honeyeaters of Australia. The resemblances are due to convergent evolution brought about by a similar nectar-feeding lifestyle.Some sunbird species can take nectar by hovering like a hummingbird, but they usually perch to feed. Several sunbird and sugarbird species breed in winter when most flowers are out, but when it is colder. The Purple Sunbirds in no Tropical or Ecuatorial areas synchronize their breeding activities with the time when the largest number of flowers are available. A sunbird that breed outside of the equatorial regions are mostly seasonal breeders, with the majority of these species breeding in the wet season. This timing reflects the increased availability of insect prey for the growing young. Where species, like the buff-throated sunbird, breed in the dry season, it is thought to be associated with the flowering of favoured food plants. Species of sunbird in the equatorial areas breed throughout the year. They are generally monogamous and often territorial, although a few species of sunbirds have lekking behaviour. The nests of sunbirds are generally purse-shaped, enclosed, suspended from thin branches with generous use of spiderweb. The nests of the spiderhunters are different, both from the sunbirds and in some cases from each other. Some, like the little spiderhunter, are small woven cups attached to the underside of large leaves; that of the yellow-eared spiderhunter is similarly attached but is a long tube. The nests of spiderhunters are inconspicuous, in contrast to those of the other sunbirds which are more visible. In most species the female alone constructs the nest. Up to four eggs are laid. The female builds the nest and incubates the eggs alone, although the male assists in rearing the nestlings.In the spiderhunters both sexes help to incubate the eggs.The nests of sunbirds and spiderhunters are often targeted by brood parasites such as cuckoos and honeyguides.
