Hylocitrea
The hylocitrea (''Hylocitrea bonensis''), also known as the yellow-flanked whistler or olive-flanked whistler, is a species of bird that is endemic to montane forests on the Indonesian island of Sulawesi.Boles, W. E. (2007). Yellow-flanked Whistler (Hylocitrea bonensis). pp. 411 in: Del Hoyo, J.; Elliot, A., & Christie D. eds. (2007). ''Handbook of the Birds of the World. Vol. 12. Picathartes to Tits and Chickadees.'' Lynx Edicions, Barcelona. It is monotypic within the genus ''Hylocitrea'', and has traditionally been considered a member of the family Pachycephalidae, but recent genetic evidence suggests it should be placed in a monotypic subfamily of the family Bombycillidae, or even its own family, Hylocitreidae. A 2019 study found it to be a sister group to a clade containing the hypocolius (Hypocoliidae) and the extinct Hawaiian honeyeaters (Mohoidae), with the clade containing all three being a sister group to the silky-flycatchers (Ptiliogonatidae).

Bombycillidae
The waxwings are three species of passerine birds classified in the genus ''Bombycilla''. They are pinkish-brown and pale grey with distinctive smooth plumage in which many body feathers are not individually visible, a black and white eyestripe, a crest, a square-cut tail and pointed wings. Some of the wing feathers have red tips, the resemblance of which to sealing wax gives these birds their common name. According to most authorities, this is the only genus placed in the family Bombycillidae, although sometimes the family is extended to include related taxa that are more usually included in separate families: silky flycatchers (Ptiliogonatidae (e.g. '' Phainoptila'')), ''Hypocolius'' (Hypocoliidae), ''Hylocitrea'' (Hylocitreidae), palmchats (Dulidae) and the Hawai'ian 'honeyeaters' (Mohoidae). There are three species: the Bohemian waxwing (''B. garrulus''), the Japanese waxwing (''B. japonica'') and the cedar waxwing (''B. cedrorum''). Waxwings are not long-distance migrants, ...

Mohoidae
Mohoidae, also known as the Hawaiian honeyeaters, is a family of Hawaiian species of recently extinct, nectarivorous songbirds in the genera '' Moho'' (ōō) and ''Chaetoptila'' (kioea). These now extinct birds form their own family, representing the only complete extinction of an entire avian family in modern times, when the disputed family Turnagridae is regarded as invalid. The last surviving species in the family, the Kauai O'o (''Moho braccatus''), became extinct after 1987. Taxonomy Until recently, these birds were thought to belong to the family Meliphagidae (honeyeaters) due to their very similar appearance and behavior, including many morphological details. However, a 2008 study argued, on the basis of a phylogenetic analysis of DNA from museum specimens, that the genera ''Moho'' and ''Chaetoptila'' are not even closely related to the Meliphagidae but instead belong to a group within the Passerida that includes the waxwings and the palmchat; they appear especially c ...

Grey Hypocolius
The grey hypocolius or simply hypocolius (''Hypocolius ampelinus'') is a small passerine bird species. It is the sole member of the genus ''Hypocolius'' and it is placed in a family of its own, the Hypocoliidae. This slender and long tailed bird is found in the dry semi-desert region of northern Africa, Arabia, Afghanistan, Pakistan, and western India. They fly in flocks and forage mainly on fruits, migrating south in winter. Description The grey hypocolius is a slim bird with a long tail, slight crest and thick, short hook-tipped bill. Its shape and soft, satiny plumage resembles that of the waxwing. Birds are mainly a uniform grey or brownish-grey colour, with males having a black triangular mask around the eyes. They have white-tipped black primary wing feathers and a black terminal band on the tail. Adults are about 19–21 cm in length. The head feathers are raised when the bird is excited. They fly in a straight non-undulating style and when hopping in shrubbery, can ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachycephalidae
The Pachycephalidae are a family of bird species that includes the whistlers, shrikethrushes, and three of the pitohuis, and is part of the ancient Australo-Papuan radiation of songbirds. The family includes 64 species that are separated into five genera. Its members range from small to medium in size, and occupy most of Australasia. Australia and New Guinea are the centre of their diversity and, in the case of the whistlers, the South Pacific islands as far as Tonga and Samoa and parts of Asia as far as India. The exact delimitation of boundaries of the family are uncertain, and one species, the golden whistler, has been the subject of intense taxonomic scrutiny in recent years, with multiple subspecies and species-level revisions. Taxonomy and systematics The family Pachycephalidae was introduced (as the subfamily Pachycephalinae) by the English ornithologist William John Swainson in 1832. The genera ''Pachycare'', ''Hylocitrea'', the crested bellbird and the crested shriket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Described In 1925
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species.

Bombycilloidea
Bombycilloidea is a superfamily of passerine birds that contains ten living species. They are found in North, Central America, most of the Palearctic, the Arabian Peninsula, the islands of Hispaniola and Sulawesi, and formerly the Hawaiian Islands. Taxonomy The superfamily includes only ten extant species. It is sister to a clade containing Muscicapoidea, Certhoidea and Regulidae (both clades are contained within the parvorder Muscicapida), from which it diverged during the mid-late Oligocene, about 25 million years ago. The common ancestor for both clades lived in Eurasia; at some point, the ancestral Bombycilloidea arrived in North America where they rapidly radiated into multiple families. One of these lineages moved back into Eurasia, where it gave rise to several lineages that stayed in Eurasia or colonized Wallacea or Hawaii. Two families, the waxwings (Bombycillidae) and silky-flycatchers (Ptiliogonatidae) contain several species and are widespread throughout the Hola ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Silky-flycatcher
The silky-flycatchers are a small family, Ptiliogonatidae, of passerine birds. The family contains only four species in three genera. They were formerly lumped with waxwings and hypocolius in the family Bombycillidae, and they are listed in that family by the Sibley-Monroe checklist. The family is named for their silky plumage and their aerial flycatching techniques, although they are unrelated to the Old World flycatchers (Muscicapidae) and the tyrant flycatchers (Tyrannidae). They occur mainly in Central America from Panama to Mexico, with one species, the phainopepla, extending northwards into the southwestern US. Most do not engage in long-distance migration (instead wandering widely in search of fruit), but the phainopepla is migratory over the northern part of its range. They are related to waxwings, and like that group have soft silky plumage, usually gray or pale yellow in color. All species, with the exception of the black-and-yellow phainoptila, have small crests. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...
