Bornean Bulbul
The Bornean bulbul (''Rubigula montis'') is a member of the bulbul family of passerine birds. It is endemic to the island of Borneo. Taxonomy and systematics The Bornean bulbul was previously placed in genus ''Pycnonotus''. This genus was found to be polyphyletic in recent molecular phylogenetic studies and five bulbul species, including the Bornean bulbul, moved to ''Rubigula''. Until 2008, the Bornean bulbul was considered as conspecific with the black-capped, black-crested, ruby-throated and flame-throated bulbul The flame-throated bulbul (''Rubigula gularis'') is a member of the bulbul family of passerine birds and the state bird of Goa. It is found only in the forests of the Western Ghats in southern India. Formerly included as a subspecies of ''Pycno ...s. Some authorities have considered the Bornean bulbul to be a subspecies of the black-capped bulbul. Description The Bornean bulbul has a black crest, yellow throat, and brownish eyes.

Richard Bowdler Sharpe
Richard Bowdler Sharpe (22 November 1847 – 25 December 1909) was an English zoologist and ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum. He described many new species of bird and also has had species named in his honour by other ornithologists including Sharpe's longclaw (''Macronyx sharpei'') and Sharpe's starling (''Poeoptera sharpii''). Biography Richard was born in London, the first son of Thomas Bowdler Sharpe. His grandfather, Reverend Lancelot Sharpe was Rector of All Hallows Staining. His father was a publisher on Skinner Street and was best known for being the publisher of ''Sharpe's London Magazine'', an illustrated periodical (weekly but monthly from 1847). His care from the age of six was under an aunt, Magdalen Wallace, widow of the headmaster at Gramm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulbul
The bulbuls are members of a family, Pycnonotidae, of medium-sized passerine songbirds, which also includes greenbuls, brownbuls, leafloves, and bristlebills. The family is distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan. A few insular species occur on the tropical islands of the Indian Ocean. There are 160 species in 32 genera. While different species are found in a wide range of habitats, the African species are predominantly found in rainforest, whereas Asian bulbuls are predominantly found in more open areas. Taxonomy The family Pycnonotidae was introduced by the English zoologist George Robert Gray in 1840 as a subfamily Pycnonotinae of the thrush family Turdidae. The Arabic word ''bulbul'' (بلبل) is sometimes used to refer to the "nightingale" as well as the bulbul, but the English word ''bulbul'' refers to the birds discussed in this article.

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Borneo
Borneo (; id, Kalimantan) is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra. The island is politically divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The population in Borneo is 23,053,723 (2020 national censuses). Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. A little more than half of the island is in the Northern Hemisphere, including Brunei and the Malaysian portion, while the Indonesian portion spans the Northern and Southern hemisph ...

Pycnonotus
''Pycnonotus'' is a genus of frugivorous passerine birds in the bulbul family Pycnonotidae. Taxonomy and systematics The genus ''Pycnonotus'' was introduced by the German zoologist Friedrich Boie in 1826 with the Cape bulbul as the type species. The name of the genus combines the Ancient Greek words ''puknos'' "thick" or "compact" and ''-nōtos'' "-backed". The genus contains the following 32 species: * Cream-vented bulbul (''Pycnonotus simplex'') * Olive-winged bulbul (''Pycnonotus plumosus'') * Asian red-eyed bulbul (''Pycnonotus brunneus'') * Straw-headed bulbul (''Pycnonotus zeylanicus'') * Cream-eyed bulbul (''Pycnonotus pseudosimplex'') * Ashy-fronted bulbul (''Pycnonotus cinereifrons'') * White-browed bulbul (''Pycnonotus luteolus'') * Ayeyarwady bulbul (''Pycnonotus blanfordi'') * Streak-eared bulbul (''Pycnonotus conradi'') * Stripe-throated bulbul (''Pycnonotus finlaysoni'') * Flavescent bulbul (''Pycnonotus flavescens'') * Aceh bulbul (''Pycnonotus snouckaerti' ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-capped Bulbul
The black-capped bulbul (''Rubigula melanictera''), or black-headed yellow bulbul, is a member of the bulbul family of passerine birds. It is endemic to Sri Lanka. Taxonomy The black-capped bulbul was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the flycatchers in the genus ''Muscicapa'' and coined the binomial name ''Muscicapa melanictera''. The specific epithet combines the Ancient Greek ''melas'' meaning "black" with ''ikteros'' meaning "jaundice-yellow". Gmelin based his description on the "yellow-breasted fly-catcher" from Sri Lanka that had been described and illustrated in 1776 by the English naturalist Peter Brown. The black-capped bulbul was formerly placed in the genus ''Pycnonotus''. A molecular phylogenetic study of the bulbul family published in 2017 found that ''Pycnonotus'' was polyphyletic. In the revision to the generic classification t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-crested Bulbul
The black-crested bulbul (''Rubigula flaviventris'') is a member of the bulbul family of passerine birds. It is found from the Indian subcontinent to southeast Asia. Taxonomy and systematics The black-crested bulbul was originally described in the genus ''Vanga'' and later moved to genus ''Pycnonotus''. ''Pycnonotus'' was found to be polyphyletic in recent molecular phylogenetic studies and five bulbul species, including the black-crested bulbul, moved to ''Rubigula''. Until 2008, the black-crested bulbul was considered as conspecific with the black-capped, ruby-throated, flame-throated and Bornean bulbuls. Subspecies Eight subspecies are recognized: * Black-crested yellow bulbul (''P. f. flaviventris'') - ( Tickell, 1833): Found from Nepal, northern and eastern India (including Pachmarhi in central India) to southern China and central Myanmar * ''P. f. vantynei'' - Deignan, 1948: Found from eastern and southern Myanmar to southern China and northern Indochina ...

Flame-throated Bulbul
The flame-throated bulbul (''Rubigula gularis'') is a member of the bulbul family of passerine birds and the state bird of Goa. It is found only in the forests of the Western Ghats in southern India. Formerly included as a subspecies of ''Pycnonotus flaviventris'' it has since been elevated to the status of a full species. They are olive-backed with yellow undersides, a triangular orange-red throat and a white iris that stands out against the contrasting black head. They are usually seen foraging in groups in the forest canopy for berries and small insects. They have a call often with two or three tinkling notes that can sound similar to those produced by the red-whiskered bulbul. The species has been referred to in the past by names such as ruby-throated bulbul and black-headed bulbul, but these are ambiguous and could apply to other species such as '' Rubigula flaviventris'' and '' R. dispar''. Taxonomy and systematics The species was described by John Gould in December 1835 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
