White-spectacled Bulbul
The white-spectacled bulbul (''Pycnonotus xanthopygos'') is a member of the bulbul family. It is in length with a wingspan of . These birds live in fruit plantations, gardens, and cities. It is the most common member of the bulbul family in Israel and Lebanon. In Turkey, it is mainly found in the coastal Mediterranean region, but its range extends from Patara/Gelemiş near Kaş in the west to Türkoğlu in the east. Breeding populations are found from Central and Southern Turkey to Western Syria, Lebanon, Western Jordan, Israel, Sinai and western, central and southern Arabia. Both sexes are similar; juveniles have a browner hood and less obvious eye-rings than the adults. The nest – a small cup of thin twigs, grass stems, leaves and moss – is generally located in bushes and lined with hair, shredded bark and small roots. Taxonomy and systematics The white-spectacled bulbul was originally described in the genus ''Ixos''. The white-spectacled bulbul is considered to belong to ...

Friedrich Wilhelm Hemprich
Wilhelm Friedrich Hemprich (24 June 1796 – 30 June 1825) was a German naturalist and explorer. Hemprich was born in Glatz (Kłodzko), Prussian Silesia, and studied medicine at Breslau and Berlin. It was in Berlin that he became friends with Christian Gottfried Ehrenberg, the two men sharing an interest in natural history. Hemprich lectured at Berlin University on comparative physiology, and wrote ''Grundriss der Naturgeschichte'' (Compendium of Natural History) (1820). In his spare time he studied reptiles and amphibians at the zoological museum under Hinrich Lichtenstein. In 1820 Hemprich and Ehrenberg were invited to serve as naturalists on a primarily archeological expedition to Egypt, led by Prussian General von Minutoli. The two naturalists were sponsored by the Berlin Academy. In March 1821 they separated from the main party and travelled up the river Nile to Dongola, the capital of Nubia. They spent the next two years studying the natural history of that part of Egypt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
African Red-eyed Bulbul
The African red-eyed bulbul or black-fronted bulbul (''Pycnonotus nigricans'') is a species of songbird in the family Pycnonotidae. It is found in south-western Africa. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, and riverine scrub. It feeds on fruit (including Ficus), flowers, nectar, and insects. Description The African red-eyed bulbul ranges from 19 to 21 centimeters (7-8 inches) in length and weighs 30-48 grams (1-1.7 ounces). Its call is a series of loud fluty notes, usually given only by the male. Taxonomy and systematics The African red-eyed bulbul was originally described in the genus ''Turdus''. The African red-eyed bulbul is considered to belong to a superspecies along with the Himalayan bulbul, white-eared bulbul, white-spectacled bulbul, Cape bulbul, and the common bulbul. The alternate name of 'red-eyed bulbul' is also used by the Asian red-eyed bulbul. Subspecies Two subspecies are recognized: * ''P. n. nigricans'' – (Viei ...

Birds Described In 1833
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furt ...

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 31 species: Former species In previous circumscriptions the genus ''Pycnonotus'' was considerably larger. Recent taxonomic revisions have seen many species transferred to other genera. In 2010, eighteen former ''Pycnonotus'' species were reclassified into different genera, either directly from ''Pycnonotus'' or from the genus ''Andropadus'', to which they had already been transferred by some authorities. These changes were as follows: * one species was transferred to genus Stelgidillas. ** Slender-billed greenbul ( former ''Pycnonotus gracilirostri'' or ''Pycnonotus gracilirostris'') * ...

Cream-vented Bulbul
The cream-vented bulbul (''Pycnonotus simplex'') is a member of the bulbul family of passerine birds. It is found in south-eastern Asia from the Malay Peninsula to Borneo. Its natural habitat is subtropical or tropical moist lowland forests. Its breast might sometimes look a little yellow. Taxonomy and systematics Alternate names for the cream-vented bulbul include the white-eyed brown bulbul and white-eyed bulbul. The latter alternate name is also shared with the white-spectacled bulbul. Subspecies Four subspecies are recognized: * ''P. s. simplex'' - René-Primevère Lesson, Lesson, 1839: Found from Malay Peninsula to Sumatra and nearby islands. * ''P. s. perplexus'' - Chasen & Kloss, 1929: Found on Borneo and nearby islands. White-eyed populations of bulbuls on Borneo formerly thought to belong to this species are now considered a distinct species, the cream-eyed bulbul (''P. pseudosimplex''). * ''P. s. prillwitzi'' - Ernst Hartert, Hartert, 1902: Originally described as a s ...

Common Bulbul
The common bulbul (''Pycnonotus barbatus'') is a member of the bulbul family of passerine birds. It is widespread throughout most of Africa except for the very arid areas. Ten subspecies are recognised based on the geographical variation in plumage. Some of these were formerly considered as separate species: Dodson's bulbul, the Somali bulbul and the dark-capped bulbul. Taxonomy and systematics The common bulbul was formally described and illustrated in 1789 by the French botanist René Desfontaines from a specimen collected near Algiers in Algeria. He placed it with the thrushes in the genus ''Turdus'' and coined the binomial name ''Turdus barbatus''. The common bulbul is now one of 31 species placed in the genus ''Pycnonotus'' that was introduced in 1826 by the German zoologist Friedrich Boie. The genus name combines the Ancient Greek πυκνος/''puknos'' meaning "thick" or "compact" with -νωτος/''-nōtos'' meaning "-backed". The specific epithet ''barbatus'' is Latin mea ...

Cape Bulbul
The Cape bulbul (''Pycnonotus capensis'') is a member of the bulbul family of passerine birds. It is an endemic resident breeder in coastal bush, open forest, gardens and fynbos in western and southern South Africa. This species nests mainly in the southern spring from September to November. The nest is a thick-walled cup concealed by foliage in a small tree or shrub. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Cape bulbul in his ''Ornithologie'' based on a specimen collected from the Cape of Good Hope in South Africa. He used the French name ''Le merle brun du Cap de Bonne Espérance'' and the Latin ''Merula Fusca Capitis Bonae Spei''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 17 ...

White-eared Bulbul
The white-eared bulbul (''Pycnonotus leucotis'') is a member of the bulbul family. It is found in south-western Asia from India to the Arabian peninsula. Taxonomy and systematics The white-eared bulbul was originally described in the genus ''Ixos''. The white-eared bulbul is considered to belong to a superspecies along with the Himalayan bulbul, white-spectacled bulbul, African red-eyed bulbul, Cape bulbul, and the common bulbul. Formerly, some authorities considered the white-eared bulbul to be a subspecies of the Himalayan Bulbul. Subspecies Two subspecies are recognized: * Arabian white-cheeked bulbul (''P. l. mesopotamia'') - Ticehurst, 1918: Found in north-eastern Arabia, southern Iraq and south-western Iran * ''P. l. leucotis'' - (Gould, 1836): Found in southern Iran, southern Afghanistan, Pakistan and north-western India Description and vocalisations The white-eared bulbul is rotund in appearance, and has a brownish-grey body.

Christian Gottfried Ehrenberg
Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German Natural history, naturalist, zoologist, Botany, botanist, comparative anatomist, geologist, and microscopy, microscopist. He is considered to be one of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Humboldt University of Berlin, Berlin and became a friend of the famous List of explorers, explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile, Nile valley and the northern coasts of the Red Sea, where he made a special ...

Superspecies
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 (or more) 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. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant varieties), which may be a complex ranking but it is not a species complex. In most cases, a species complex is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
