In biology, phenetics, also known as taximetrics, is an attempt to classify organisms based on overall similarity, usually with respect to morphology or other observable traits, regardless of their phylogeny or evolutionary relation. It is related closely to numerical taxonomy which is concerned with the use of numerical methods for taxonomic classification. Many people contributed to the development of phenetics, but the most influential were Peter Sneath and Robert R. Sokal. Their books are still primary references for this sub-discipline, although now out of print.
A passerine is any bird of the order Passeriformes which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes, which facilitates perching.
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin oscen, "songbird". The Passeriformes contains 5,000 or so species found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song.
The Sibley–Ahlquist taxonomy is a bird taxonomy proposed by Charles Sibley and Jon E. Ahlquist. It is based on DNA–DNA hybridization studies conducted in the late 1970s and throughout the 1980s.
The parrotbills are a family, Paradoxornithidae, of passerine birds that are primarily native to East, Southeast and South Asia, with a single species in western North America, though feral populations exist elsewhere. They are generally small birds that inhabit reedbeds, forests and similar habitats. The traditional parrotbills feed mainly on seeds, e.g. of grasses, to which their robust bill, as the name implies, is well-adapted. Members of the family are usually non-migratory.
The Tyranni (suboscines) are a suborder of passerine birds that includes more than 1,000 species, the large majority of which are South American. It is named after the type genus Tyrannus. These have a different anatomy of the syrinx musculature than the oscines, hence the common name of suboscines.
The white-eyes are a family, Zosteropidae, of small passerine birds native to tropical, subtropical and temperate Sub-Saharan Africa, southern and eastern Asia, and Australasia. White-eyes inhabit most tropical islands in the Indian Ocean, the western Pacific Ocean, and the Gulf of Guinea. Discounting some widespread members of the genus Zosterops, most species are endemic to single islands or archipelagos. The silvereye, Zosterops lateralis, naturally colonised New Zealand, where it is known as the "wax-eye" or tauhou ("stranger"), from 1855. The silvereye has also been introduced to the Society Islands in French Polynesia, while the Japanese white-eye has been introduced to Hawaii.
Meliphagoidea is a superfamily of passerine birds. They contain a vast diversity of small to mid-sized songbirds widespread in the Austropacific region. The Australian Continent has the largest richness in genera and species.
Passerida is, under the Sibley-Ahlquist taxonomy, one of two parvorders contained within the suborder Passeri. While more recent research suggests that its sister parvorder, Corvida, is not a monophyletic grouping, the Passerida as a distinct clade are widely accepted.
The "Passerae" were a proposed "parvclass" of birds in the Sibley-Ahlquist taxonomy. This taxon is a variation on the theme of "near passerines", birds that were - and often still are - believed to be close relatives of the passerines. This proposed taxon was roundly rejected by subsequent cladistic analyses.
Grallina is a genus of passerine bird native to Australia and New Guinea. It is a member of a group of birds termed monarch flycatchers.
The golden monarch is a species of passerine bird in the family Monarchidae found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forest. The golden monarch displays marked sexual dimorphism, the male a striking golden colour with black mask, wings and tail, the female a golden or golden-olive colour. Both bear a characteristic 'teardrop' white pattern below the eye.
The azure-crested flycatcher or the blue-crested flycatcher, is a species of bird in the monarch flycatcher family Monarchidae. It is endemic to Fiji, where it is found on Taveuni.
The smoky robin is a species of bird in the family Petroicidae endemic to West Papua, Indonesia. Its natural habitat is subtropical or tropical moist montane forests.
The slaty robin, also known as the blue-grey robin, is a species of bird in the family Petroicidae, present in the New Guinea Highlands and sparsely in the island's northern areas. Its natural habitat is subtropical or tropical moist montane forests.
The pink robin is a small passerine bird native to southeastern Australia. Its natural habitats are cool temperate forests of far southeastern Australia. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 13.5 cm (5.3 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. The male has a distinctive white forehead spot and pink breast, with grey-black upperparts, wings and tail. The belly is white. The female has grey-brown plumage. The position of the pink robin and its Australian relatives on the passerine family tree is unclear; the Petroicidae are not closely related to either the European or American robins, but appear to be an early offshoot of the Passerida group of songbirds.
The black-sided robin, also known as the pied robin, is a species of bird in the family Petroicidae. It is widespread throughout New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.
The white-browed robin is a species of bird in the family Petroicidae. It is endemic to north-eastern Australia. Its natural habitats are forest, woodland and scrub, often near water. It formerly included the buff-sided robin as a subspecies.
Sylvioidea is a superfamily of passerine birds, one of at least three major clades within the Passerida along with the Muscicapoidea and Passeroidea. It contains about 1300 species including the Old World warblers, Old World babblers, swallows, larks and bulbuls. Members of the clade are found worldwide, but fewer species are present in the Americas.
The ashy robin, also known as the black-cheeked robin, is a species of bird in the family Petroicidae native to New Guinea.
