The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
The genus Perisoreus is a very small genus of jays from the Boreal regions of North America and Eurasia from Scandinavia to the Asian seaboard. An isolated species also occurs in north-western Sichuan of China. They belong to the Passerine order of birds in the family Corvidae. Species of Perisoreus jays are most closely related to the genus Cyanopica.
Ploceidae is a family of small passerine birds, many of which are called weavers, weaverbirds, weaver finches, or bishops. These names come from the nests of intricately woven vegetation created by birds in this family. In most recent classifications, the Ploceidae are a clade that excludes some birds that have historically been placed in the family, such as some of the sparrows, but which includes the monotypic subfamily Amblyospizinae. The family is believed to have originated in the mid-Miocene. All birds of the Ploceidae are native to the Old World, most in Africa south of the Sahara, though a few live in tropical areas of Asia. A few species have been introduced outside their native range.
The black-necked weaver is a resident breeding bird species in much of central Africa from Cameroon in the west to Kenya and southern Somalia in the east.
The pheasant pigeon is a species of large terrestrial pigeon. It is the only species of the monotypic genus Otidiphaps. The pheasant pigeon is found in the primary rainforests of New Guinea and nearby islands. It ranges primarily over hilly and lower mountain areas, but can also be found in lowlands.
The Mauritius fody is a rare species of bird in the weaver family. It is endemic to the island of Mauritius. It is classified by BirdLife International as being endangered. It is also on the United States' Endangered Species List with an endangered status.
Ploceus is a genus of birds in the weaver family, Ploceidae. They are native to the Indomalayan and Afrotropical realms.
The red-headed weaver is a species of bird in the family Ploceidae. It is placed in the monotypic genus Anaplectes and is found throughout the Afrotropics.
Anaplectes is a genus of African birds in the weaver family Ploceidae.
The white-rumped snowfinch is a species of passerine bird in the sparrow family Passeridae. It is the only member of the genus Onychostruthus. It is sometimes placed in the genus Montifringilla.
The bar-winged weaver is a species of bird in the family Ploceidae. It is found in Angola, Democratic Republic of the Congo, and Zambia.
The baglafecht weaver is a species of weaver bird from the family Ploceidae which is found in eastern and central Africa. There are several disjunct populations with distinguishable plumage patterns. Only some races display a discrete non-breeding plumage.
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.
Vieillot's black weaver is a species of bird in the family Ploceidae. It is found in southern Nigeria to Uganda, west Kenya, Angola and the Democratic Republic of the Congo. The common name is after the French ornithologist Louis Pierre Vieillot.
The Sakalava weaver sometimes known as the Sakalava fody is a species of bird in the family Ploceidae. It is endemic to Madagascar. The bird is 15 cm (5.9 in) long and weighs 20–28 g (0.71–0.99 oz).
The olive-naped weaver is a bird species in the family Ploceidae. It is found in West Africa from Senegal and Gambia to Cameroon.
The chestnut-and-black weaver is a species of bird in the family Ploceidae. It is found in West Africa from Sierra Leone to southern Nigeria.
The red-cowled widowbird is a species of bird in the weaver family Ploceidae. Red-cowled widowbirds are found in grasslands and bush clearings in East Africa. They are known for their long tails and brilliant red badges, both which act as sexual ornaments. They are often associated with other widowbird and bishop species. They are polygynous, where males acquisition of territory is an important determinant in their access to mates. Red-cowled widowbirds have a wide range and there is little concern in terms of conservation status.
