Doves
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geotrygon
''Geotrygon'' is a bird genus in the pigeon and dove family (Columbidae). Its members are called quail-doves, and all live in the Neotropics. The species of this genus have ranges from southern Mexico and Central America to the West Indies and South America. Quail-doves are ground-dwelling birds that live, nest, and feed in dense forests. They are remarkable for their purple to brown coloration with light-and-dark facial markings. The genus ''Geotrygon'' was introduced in 1847 by English naturalist Philip Henry Gosse. The name combines the Ancient Greek ''geō-'' meaning "ground-" and ''trygōn'' meaning "turtledove". The type species was subsequently designated as the crested quail-dove (''Geotrygon versicolor''). The genus contains nine species: * Grey-fronted quail-dove, ''G. caniceps'' * Key West quail-dove, ''G. chrysia'' * † Puerto Rican quail-dove, ''Geotrygon larva'' - prehistoric * White-fronted quail-dove or Hispaniolan quail-dove, ''G. leucometopius'' * Ruddy qu ...

Domestic Pigeon
The domestic pigeon (''Columba livia domestica'' or ''Columba livia'' ''forma'' ''domestica'') is a pigeon subspecies that was derived from the rock dove (also called the rock pigeon). The rock pigeon is the world's oldest domesticated bird. Mesopotamian cuneiform tablets mention the domestication of pigeons more than 5,000 years ago, as do Egyptian hieroglyphics. Research suggests that domestication of pigeons occurred as early as 10,000 years ago. Pigeons have made contributions of considerable importance to humanity, especially in times of war. In war the homing ability of pigeons has been put to use by making them messengers. So-called war pigeons have carried many vital messages and some have been decorated for their services. Medals such as the Croix de Guerre, awarded to Cher Ami, and the Dickin Medal awarded to the pigeons G.I. Joe and Paddy, amongst 32 others, have been awarded to pigeons for their services in saving human lives. Despite this, city pigeons today ...

Feral Pigeon
Feral pigeons (''Columba livia domestica'' or ''Columba livia forma urbana''), also called city doves, city pigeons, or street pigeons,Nagy, Kelsi, and Johnson, Phillip David. ''Trash animals: how we live with natures filthy, feral, invasive, and unwanted species''. Minneapolis (Minn.), University of Minnesota Press, 2013.Blechman, Andrew D. ''Pigeons: The Fascinating Saga of the World’s Most Revered and Reviled Bird'', St Lucia, Qld., University of Queensland Press, 2007. are descendants of domestic pigeons (''Columba livia domestica'') that have returned to the wild. The domestic pigeon was originally bred from the wild rock dove, which naturally inhabits sea-cliffs and mountains. Rock, domestic, and feral pigeons are all the same species and will readily interbreed. Feral pigeons find the ledges of buildings to be a substitute for sea cliffs, have become adapted to urban life, and are abundant in towns and cities throughout much of the world.

Sandgrouse
Sandgrouse is the common name for Pteroclidae , a family of sixteen species of bird, members of the order Pterocliformes . They are traditionally placed in two genera. The two central Asian species are classified as '' Syrrhaptes'' and the other fourteen species, from Africa and Asia, are placed in the genus '' Pterocles''. They are ground dwelling birds restricted to treeless, open country, such as plains, savannahs, and semi-deserts. They are distributed across northern, southern, and eastern Africa, Madagascar, the Middle East, and India through central Asia. The ranges of the black-bellied sandgrouse and the pin-tailed sandgrouse even extend into the Iberian Peninsula and France, and Pallas's sandgrouse occasionally breaks out in large numbers from its normal range in Asia. Description Sandgrouse have small, pigeon-like heads and necks and sturdy compact bodies. They range in size from in length and from in weight. The adults are sexually dimorphic with the males being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crop Milk
Crop milk is a secretion from the lining of the crop of parent birds that is regurgitated to young birds. It is found among all pigeons and doves where it is referred to as pigeon milk. An analog to crop milk is also secreted from the esophagus of flamingos and the male emperor penguin. Description Crop milk bears little physical resemblance to mammalian milk. Crop milk is a semi-solid substance somewhat like pale yellow cottage cheese. It is extremely high in protein and fat, containing higher levels than cow or human milk. A 1939 study of pigeon crop milk showed, however, that the substance did not contain carbohydrates. It has also been shown to contain anti-oxidants and immune-enhancing factors which contribute to milk immunity. Like mammalian milk, crop milk contains IgA antibodies. It also contains some bacteria. Unlike mammalian milk, which is an emulsion, pigeon crop milk consists of a suspension of protein-rich and fat-rich cells that proliferate and detach fro ...

Pink-necked Green Pigeon
The pink-necked green pigeon (''Treron vernans'') is a species of bird of the pigeon and dove family, Columbidae. It is a common species of Southeast Asia, found from Myanmar and Vietnam south through to the major islands of Indonesia and the Philippines (where it is called "punay"). It is a medium-sized pigeon with predominantly green plumage; only the male has the pink neck that gives the species its name. The species lives in a wide range of forested and human-modified habitats and is particularly found in open habitats. Its diet is dominated by fruit, in particular figs. Pairs lay two eggs in a flimsy twig nest in a tree, shrub, or hedge, and work together to incubate the eggs and raise the chicks. The species is thought to be an important disperser of fruit seeds. The species has adapted well to human changes to the environment, and can be found in crowded cities as long as fruiting trees are present. Taxonomy Carl Linnaeus described the pink-necked green pigeon as ''Colu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Realm
The Australasian realm is a biogeographic realm that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccan islands (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas. The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the Oceanian r ...

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 passe ...

William Elford Leach
William Elford Leach FRS (2 February 1791 – 25 August 1836) was an English zoologist and marine biologist. Life and work Elford Leach was born at Hoe Gate, Plymouth, the son of an attorney. At the age of twelve he began a medical apprenticeship at the Devonshire and Exeter Hospital, studying anatomy and chemistry. By this time he was already collecting marine animals from Plymouth Sound and along the Devon coast. At seventeen he began studying medicine at St Bartholomew's Hospital in London, finishing his training at the University of Edinburgh before graduating MD from the University of St Andrews (where he had never studied). From 1813 Leach concentrated on his zoological interests and was employed as an 'Assistant Librarian' (what would later be called Assistant Keeper) in the Natural History Department of the British Museum, where he had responsibility for the zoological collections. Here he threw himself into the task of reorganising and modernising these col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Museum
The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is among the largest and most comprehensive in existence. It documents the story of human culture from its beginnings to the present.Among the national museums in London, sculpture and decorative and applied art are in the Victoria and Albert Museum; the British Museum houses earlier art, non-Western art, prints and drawings. The National Gallery holds the national collection of Western European art to about 1900, while art of the 20th century on is at Tate Modern. Tate Britain holds British Art from 1500 onwards. Books, manuscripts and many works on paper are in the British Library. There are significant overlaps between the coverage of the various collections. The British Museum was the first public national museum to cover all fields of knowledge. The museum was established in 1753, largely b ...
