The common sunbird-asity or sunbird asity (Neodrepanis coruscans) is a species of bird in the family Philepittidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist lowland forests.
The genus Neodrepanis is characterised by a tiny body with a short tail, a fine, strongly decurved bill and, during the breeding season, strong sexual dichromatism. Males in breeding plumage are brilliant blue and black above and variably bright yellow below, with extraordinary blue and green facial caruncles. Females, males in non-breeding plumage and immatures are dull blue-green above, lack caruncles and are variably yellowish below; some female-plumaged birds (at least for Common Sunbird Asity) have a half-sized caruncle and may be immature males. In winter, males are often seen with traces of breeding plumage coloration.
Male common sunbird-asities are duller than yellow-bellied in almost all respects. The former have brilliant royal blue-fringed back crown, nape, mantle and scapular feathers, and narrow but fairly conspicuous yellow fringes to the secondaries and greater and median wing coverts. Their underparts are dull, deep yellow, with strong olive-brown streaking in the centre of the breast; the flanks, belly and undertail coverts are unstreaked and somewhat brighter. The caruncle is almost square and turquoise-blue, rather greener around the eye. It extends only a short distance in front of the eye, and is not connected to the area of blue (basally) and green (distally) bare skin that overlies the basal quarter of the bill. [2]
The asities are a family of birds, Philepittidae, that are endemic to Madagascar. The asities consist of four species in two genera. The Neodrepanis species are known as sunbird-asities and were formerly known as false sunbirds.
The blue-winged warbler is a fairly common New World warbler, 11.5 cm (4.5 in) long and weighing 8.5 g (0.30 oz). It breeds in eastern North America in southern Ontario and the eastern United States. Its range is extending northwards, where it is replacing the very closely related golden-winged warbler.
The souimanga sunbird is a small passerine bird of the sunbird family, Nectariniidae. It is native to the islands of the western Indian Ocean where it occurs on Madagascar, the Aldabra Group and the Glorioso Islands.
The yellow-bellied sunbird-asity is a small species of passerine bird from the asity family. The male has black upper parts with a bluish sheen and yellow underparts, and is sometimes known simply as the yellow-bellied asity. It is found only in montane rainforests of Madagascar where it feeds on nectar that it sips from flowers, defending a good nectar source from other nectar-feeding birds. It is listed by the International Union for Conservation of Nature as "vulnerable" due to the diminution and fragmentation of its forest habitat.
Mrs. Gould's sunbird is a sunbird species native to forests and shrublands from the southern foothills of the Himalayas to Southeast Asia.
The fire-capped tit is a small, 10 cm (3.9 in) long, weighing about 7 g (0.25 oz) bird species assigned to the family Paridae, that breeds in the temperate forest bordering the Himalayas to the south, in the Hengduan Shan and Nujiang Shan on the Myanmar-China border, the Micah Shan and Daba Shan on the Northern Sichuan border. It winters down hill and further south. Further to the east, birds tend to be smaller and the plumage becomes gradually darker.
The shining sunbird is a species of bird in the family Nectariniidae.
Moreau's sunbird is a species of bird in the family Nectariniidae. It is endemic to Kilolo District of Morogoro Region in Tanzania where its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss and the International Union for Conservation of Nature has assessed it as being "near-threatened".
The nelicourvi weaver is a species of bird in the family Ploceidae. It is endemic to Madagascar. Together with its closest relative, the sakalava weaver, it is sometimes placed in a separate genus Nelicurvius. A slender, sparrow-like bird, it is 15 cm (5.9 in) long and weighing 20–28 g (0.71–0.99 oz). Breeding males have a black bill and head, brown eyes, yellow collar, grey belly, chestnut-brown lower tail coverts, olive back, and blackish flight feathers edged greenish. Non-breeding males have mottled grey and green heads. In the breeding female the front of the head is yellow and the back olive green, with a broad yellow eyebrow. It builds solitary, roofed, retort-shaped nests, hanging by a rope from a branch, vine or bamboo stem, in an open space. It primarily feeds on insects, looking on its own or in very small groups, often together with long-billed bernieria. Its natural habitat is subtropical or tropical moist lowland and mountain forests. The conservation status of Nelicourvi weaver is least concern according to the IUCN Red List.
The emerald tanager is a species of bird in the tanager family Thraupidae. It is found in Colombia, Costa Rica, Ecuador, and Panama. Described by the English ornithologists PL Sclater and Osbert Salvin in 1869, it is a medium-sized species that has a length of 10.6–13 cm (4.2–5.1 in) and a mass of 18–20.5 g (0.63–0.72 oz). It can be identified by its bright green plumage, with black streaking on the back and wings, and a black auricular patch and beak. It also has yellow on the crown and rump. The species shows slight sexual dimorphism, with the females being duller and having yellow-green in place of yellow on the head.
The blue-banded toucanet is a near-passerine bird in the toucan family Ramphastidae. It is found in Bolivia and Peru.
The Kerguelen shag is a species of cormorant endemic to the Kerguelen Islands in the southern Indian Ocean, one of the most isolated places on Earth. Many authorities consider it a subspecies of the imperial shag.
