Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...

Birds Of South Asia
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. Bi ...

Birds Of The Himalayas
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur (''Semnopithecus schistaceus'') Lowland forests On the Indo-Gangetic plain at the base of the mountains, an alluvial plain drained by the Indus and Ganges-Brahmaputra river systems, vegetation varies from west to east with rainfall. The deserts and xeric shrublands, xeric Northwestern thorn scrub forests occupy the plains of Punjab, Pakistan, Pakistani and the Punjab, India, Indian Punjab. Further east lie the Upper Gangetic Plains moist deciduous forests of Uttarakhand and Uttar Pradesh and the Lower Gangetic Plains moist deciduous forests of Bi ...

Drongos
The drongos are a family, Dicruridae, of passerine birds of the Old World tropics. The 30 species in the family are placed in a single genus, ''Dicrurus''. Drongos are mostly black or dark grey, short-legged birds, with an upright stance when perched. They have forked tails and some have elaborate tail decorations. They feed on insects and small birds, which they catch in flight or on the ground. Some species are accomplished mimics and have a variety of alarm calls, to which other birds and animals often respond. They are known to utter hoax alarm calls that scare other animals off food, which the drongo then claims. Taxonomy The genus ''Dicrurus'' was introduced by French ornithologist Louis Pierre Vieillot for the drongos in 1816. The type species was subsequently designated as the balicassiao (''Dicrurus balicassius'') by English zoologist George Robert Gray in 1841. The name of the genus combines the Ancient Greek words ''dikros'' "forked" and ''oura'' "tail". "Drongo" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Common Iora
The common iora (''Aegithina tiphia'') is a small passerine bird found across the tropical Indian subcontinent and Southeast Asia, with populations showing plumage variations, some of which are designated as subspecies. A species found in scrub and forest, it is easily detected from its loud whistles and the bright colours. During the breeding season, males display by fluffing up their feathers and spiral in the air appearing like a green, black, yellow, and white ball. Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the common iora in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Green Indian Fly-Catcher". Edwards based his hand-coloured etching on a specimen that had been sent from Bengal to the silk-pattern designer and naturalist Joseph Dandridge in London. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawking (birds)
Hawking is a feeding strategy in birds involving catching flying insects in the air. The term usually refers to a technique of sallying out from a perch to snatch an insect and then returning to the same or a different perch, though it also applies to birds that spend almost their entire lives on the wing. This technique is called "flycatching" and some birds known for it are several families of "flycatchers": Old World flycatchers, monarch flycatchers, and tyrant flycatchers. Other birds, such as swifts, swallows, and nightjars, also take insects on the wing in continuous aerial feeding. The term "hawking" comes from the similarity of this behavior to the way hawks take prey in flight, although, whereas raptors may catch prey with their feet, hawking is the behavior of catching insects in the bill. Many birds have a combined strategy of both hawking insects and gleaning them from foliage. Flycatching The various methods of taking insects have been categorized as: gleaning (per ...

Robert Cecil Beavan
Captain Robert Cecil Beavan (1841 – 3 February 1870), corresponding member of the Zoological Society of London, served in India with the Bengal Staff Corps for 10 years. During his short life he collected specimens of birds and eggs at various locations. He contributed notes to the Ibis journal as wells as the Proceedings of the Zoological Society of London. He also collaborated with Allan Octavian Hume. His collection of eggs and birds went into the Natural History Museum through the Tweeddale and Godman-Salvin collections. In 1864 Beavan worked at Barrackpore and the winter of that year was spent in the Maunbhoom District, an area studied earlier by Samuel Tickell and Edward Blyth. His notes on this period were published in ''The Ibis'' (1865) entitled "Notes on various Indian Birds". While still in service he collected in the Andaman Islands and with additional information from Colonel Robert Christopher Tytler, wrote "The Avifauna of the Andaman Islands" in the ''Ibis ...

Charles Vaurie
Charles Vaurie (7 July 1906, Beaulieu-sur-Dordogne, France – 13 May 1975, Reading, Pennsylvania) was a French-born American ornithologist. He was born in France, but moved to Trenton, New Jersey as a youth. He studied at New York University and then qualified as a dentist at the University of Pennsylvania in 1928. An interest in painting birds developed, and after marrying his entomologist wife, Patricia Wilson, in 1934, the two shared numerous field trips. Vaurie became associated with the American Museum of Natural History and by 1946 he was a Research Associate. He went on to produce more than 150 ornithological publications. His most important work was a systematic review of Palearctic birds. By 1956, he was a full-time ornithologist at AMNH, and rose to Curator by 1967. At the time of his death he was a member of the Standing Committee on Ornithological Nomenclature of the International Ornithological Congress.
