Magpie Starling
The magpie starling (''Speculipastor bicolor'') is a member of the Sturnidae, starling family from eastern Africa. Description The magpie starling is about in length. The white patches at base of primaries are obvious in flight. The male is a shiny blue-black on upperparts, head and upper breast, with mostly white below and bloodred eyes. The female is a dull blackish above with dark grey crown, and a dark grey throat is separated from white belly by a glossy black breast band. Her eyes are red or orange-red. The juvenile (animal), Juvenile is brown with a white belly; eyes brown, becoming orange-red in as the bird matures. Exceptional young birds are entirely white below, including chin and throat. The call is a prolonged soft babbling ''quereeeh quaaa kereek quak-quak, suaaaa, cherak-chik-chak''...mixed higher harsh notes. Distribution and habitat It is a gregarious nomadic pied starling of dry brush and thorn-scrub in northern and eastern Kenya. It is also found in Ethiopia ...

Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and Herpetology, herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum, Berlin, Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893). He also wrote ''Die Vögel der Bismarckinseln'' (1899). He was editor of the ''Journal für Ornithologie'' from 1894 to 1921. A number of birds are named after him, including Reichenow's woodpecker and Reichenow's firefinch. His son Eduard Reichenow was a famous protozoologist. Reichenow is known for his classification of birds into six groups, described, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Primaries
Primary elections or primaries are elections held to determine which candidates will run in an upcoming general election. In a partisan primary, a political party selects a candidate. Depending on the state and/or party, there may be an "open primary", in which all voters are eligible to participate, or a "closed primary", in which only members of a political party can vote. Less common are nonpartisan primaries in which all candidates run regardless of party. The origins of primary elections can be traced to the progressive movement in the United States, which aimed to take the power of candidate nomination from party leaders to the people. However, political parties control the method of nomination of candidates for office in the name of the party. Other methods of selecting candidates include caucuses, internal selection by a party body such as a convention or party congress, direct nomination by the party leader, and nomination meetings. A similar procedure for selecting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Flight
Flight or flying is the motion (physics), motion of an Physical object, object through an atmosphere, or through the vacuum of Outer space, space, without contacting any planetary surface. This can be achieved by generating aerodynamic lift associated with gliding flight, gliding or air propulsion, propulsive thrust, aerostatically using buoyancy, or by ballistics, ballistic movement. Many things can fly, from Flying and gliding animals, animal aviators such as birds, bats and insects, to natural gliders/parachuters such as patagium, patagial animals, anemochorous seeds and ballistospores, to human inventions like aircraft (airplanes, helicopters, airships, balloons, etc.) and rockets which may propel spacecraft and spaceplanes. The engineering aspects of flight are the purview of aerospace engineering which is subdivided into aeronautics, the study of vehicles that travel through the atmosphere, and astronautics, the study of vehicles that travel through space, and ballistics, ...

Breast
The breasts are two prominences located on the upper ventral region of the torso among humans and other primates. Both sexes develop breasts from the same embryology, embryological tissues. The relative size and development of the breasts is a major secondary sex distinction between females and males. There is also considerable Bra size, variation in size between individuals. Permanent Breast development, breast growth during puberty is caused by estrogens in conjunction with the growth hormone. Female humans are the only mammals that permanently develop breasts at puberty; all other mammals develop their mammary tissue during the latter period of pregnancy. In females, the breast serves as the mammary gland, which produces and secretes milk to feed infants. Subcutaneous fat covers and envelops a network of lactiferous duct, ducts that converge on the nipple, and these tissue (biology), tissues give the breast its distinct size and globular shape. At the ends of the ducts are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Juvenile (animal)
A juvenile is an individual organism (especially an animal) that has not yet reached its adult form, sexual maturity or size. Juveniles can look very different from the adult form, particularly in colour, and may not fill the same niche as the adult form. In many organisms the juvenile has a different name from the adult (see List of animal names). Some organisms reach sexual maturity in a short metamorphosis, such as ecdysis in many insects and some other arthropods. For others, the transition from juvenile to fully mature is a more prolonged process—puberty in humans and other species (like higher primates and whales), for example. In such cases, juveniles during this transformation are sometimes called subadults. Many invertebrates cease development upon reaching adulthood. The stages of such invertebrates are larvae or nymphs. In vertebrates and some invertebrates (e.g. spiders), larval forms (e.g. tadpoles) are usually considered a development stage of their own, an ...

Nomadic
Nomads are communities without fixed habitation who regularly move to and from areas. Such groups include hunter-gatherers, pastoral nomads (owning livestock), tinkers and trader nomads. In the twentieth century, the population of nomadic pastoral tribes slowly decreased, reaching an estimated 30–40 million nomads in the world . Nomadic hunting and gathering—following seasonally available wild plants and game—is by far the oldest human subsistence method known. Pastoralists raise herds of domesticated livestock, driving or accompanying them in patterns that normally avoid depleting pastures beyond their ability to recover. Nomadism is also a lifestyle adapted to infertile regions such as steppe, tundra, or ice and sand, where mobility is the most efficient strategy for exploiting scarce resources. For example, many groups living in the tundra are reindeer herders and are semi-nomadic, following forage for their animals. Sometimes also described as "nomadic" are var ...

Starling
Starlings are small to medium-sized passerine (perching) birds known for the often dark, glossy iridescent sheen of their plumage; their complex vocalizations including mimicking; and their distinctive, often elaborate swarming behavior, known as murmuration. All members of the family ''Sturnidae'', commonly called sturnids, are known collectively as starlings. The Sturnidae are named for the genus '' Sturnus'', which in turn comes from the Latin word for starling, ''sturnus''. The family contains 128 species which are divided into 36 genera. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for ...
