The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes the canaries, siskins, redpolls, serins, grosbeaks and euphonias, as well as the morphologically divergent Hawaiian honeycreepers.
Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller number of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.
The American teal or green-winged teal is a common and widespread duck that breeds in the northern areas of North America except on the Aleutian Islands. It was considered conspecific with the Eurasian teal for some time, but has since been split into its own species. The American Ornithological Society continues to debate this determination; however, nearly all other authorities consider it distinct based on behavioral, morphological, and molecular evidence. The scientific name is from Latin Anas, "duck" and carolinensis, "of Carolina".
The Sudan golden sparrow is a small species of bird in the sparrow family found in sub-Saharan Africa. It is a famous cage bird, and in aviculture, it is known as the golden song sparrow. The Arabian golden sparrow and this species are sometimes considered one species, as the "golden sparrow".
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use.
The long-tailed paradise whydah or eastern paradise whydah is from the family Viduidae of the order Passeriformes. They are small passerines with short, stubby bills found across Sub-Saharan Africa. They are mostly granivorous and feed on seeds that have ripen and fall on the ground. The ability to distinguish between males and females is quite difficult unless it is breeding season. During this time, the males molt into breeding plumage where they have one distinctive feature which is their long tail. It can grow up to three times longer than its own body or even more. Usually, the whydahs look like ordinary sparrows with short tails during the non-breeding season. In addition, hybridization can occur with these paradise whydahs. Males are able to mimic songs where females can use that to discover their mate. However, there are some cases where females don't use songs to choose their mate but they use either male characteristics like plumages or they can have a shortage of options with song mimicry. Paradise whydahs are brood parasites. They won't destroy the eggs that are originally there but will lay their own eggs in other songbirds nest. Overall, these whydahs are considered least concerned based on the IUCN Red List of threatened species.
The true koels, Eudynamys, are a genus of cuckoos from Asia, Australia and the Pacific. They are large sexually dimorphic cuckoos that eat fruits and insects and have loud distinctive calls. They are brood parasites, laying their eggs in the nests of other species.
Pelusios is a genus of African side-necked turtles. With 17 described species, it is one of the most diverse genera of the turtle order (Testudines).
Coccyzus is a genus of cuckoos which occur in the Americas. The genus name is from Ancient Greek kokkuzo, which means to call like a common cuckoo. The genus includes the lizard cuckoos that were formerly included in the genus Saurothera.
The streaky-headed seedeater or streaky-headed canary is a small passerine bird in the finch family. It is an unobtrusive but widespread species in suitable habitats of southern Africa. Its presence in an area is revealed foremost by its callnotes.
The black-chinned quailfinch also known as the red-billed quailfinch, is a common subspecies of estrildid finch found in central Africa. It has an estimated global extent of occurrence of 450,000 km2. It is found in Angola, Burundi, the Republic of Congo, the Democratic Republic of the Congo, Equatorial Guinea, Gabon, Rwanda, Tanzania and Zambia. The IUCN has classified the species as being of least concern. Some taxonomists consider it to be conspecific with the other species of quailfinch.
The black-faced quailfinch, is a common subspecies of estrildid finch found in western and central of Africa. Some taxonomists consider it to be conspecific with the African quailfinch, others consider all three species to be conspecific.
The locust finch or locustfinch is a species of waxbill found in south-central and south-eastern Africa. It is the only species in the genus Paludipasser. It is sometimes placed in the genus Ortygospiza.
The black cuckoo is a species of cuckoo in the family Cuculidae. The species is distributed widely across sub-Saharan Africa. There are two subspecies. This cuckoo has a very wide range and is quite common so it is classified as a least-concern species by the International Union for Conservation of Nature.
The thick-billed cuckoo is a species of cuckoo in the family Cuculidae. It is monotypic within the genus Pachycoccyx. It can easily be distinguished from other brood parasitic cuckoo species by its very thick bill, which is shaped in a rather hawk-like fashion.
The cuckoo-finch, also known as the parasitic weaver or cuckoo weaver, is a small passerine bird now placed in the family Viduidae with the indigobirds and whydahs. It occurs in grassland in Africa south of the Sahara. The male is mainly yellow and green while the female is buff with dark streaks. They lay their eggs in the nests of other birds.
The Cameroon indigobird is a species of bird in the family Viduidae. It is considered by some authors to be a subspecies of the variable indigobird. They range from Sierra Leone to east Cameroon, north east Zaire and South Sudan.
The quailfinch indigobird is a small songbird. It is a resident breeding bird in The Gambia, Nigeria and Cameroon. It occurs in isolated localities, especially on river flood plains.
The forest robin or orange-breasted forest robin is a species of bird from Central and West Africa. It is monotypic in the genus Stiphrornis. It has been placed in the family Turdidae, but is now generally placed in Muscicapidae in the group popularly known as chats. Most taxonomists consider it a single species, but some reviews have recommended recognizing 5 species. It has a total length of around 12 cm, has dark upperparts, and a throat and chest that, depending on the subspecies, is yellow-orange or deep orange.
The African quailfinch, spectacled quailfinch, or white-chinned quailfinch, is a common species of estrildid finch found in eastern and southern Africa. Some taxonomists consider it to be conspecific with the black-faced quailfinch and the black-chinned quailfinch, others consider all three species to be conspecific.
