Margaret's Batis
Margaret's batis (''Batis margaritae'') or Boulton's batis, is a species of small passerine bird in the wattle-eyes family, Platysteiridae. It is found in south western central Africa. Taxonomy Margaret's batis was described by the American zoologist Wolfrid Rudyerd Boulton in 1934. The binomial and common names honour the American historian and novelist Margaret Leech (1893-1974). Two subspecies are recognised: *''B. m. margaritae'' Boulton, 1934 – Mount Moco in western Angola. *''B. m. kathleenae'' White, C.M.N. 1941 – southern Democratic Republic of Congo in southern Katanga and north western Zambia; possibly also in the extreme east of Angola, in eastern Moxico. Description Margaret's batis is a small, mainly black and white shrike-like bird with a black face mask and reddish eye, in a mainly dark grey head. They have white underparts with a broad black breast band in both sexes, with black wings which are marked in the male with a white wing stripe while the female ...

Wolfrid Rudyerd Boulton
Wolfrid Rudyerd Boulton (April 5, 1901 – January 24, 1983) was an American ornithologist who worked extensively in Africa. Boulton held positions at the American Museum of Natural History and the Carnegie Museum of Natural History and traveled widely on expeditions to Africa. With his first wife, ethnomusicologist Laura Boulton, he made the first recordings of African tropical bird calls. Boulton was recruited into the Office of Strategic Services (OSS) during the Second World War because of his knowledge of Africa and his experience in foreign travel. He was responsible for monitoring the supply of uranium ore from the Belgian Congo for the Manhattan Project. Boulton transferred to the Central Intelligence Agency (CIA) in 1947 and resigned in 1958. Boulton moved to Southern Rhodesia in 1959 with his third wife and established the Atlantica Foundation, a charitable organization to encourage the study of African birds. The foundation received funding from the CIA and Boul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Central Africa
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 Metabolism (, from el, μεταβολή ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run cell ... rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, 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 Flightless bird, loss of ...

Batis (bird)
''Batis'' (pronounced BAT-iss) is a genus of passerine birds in the wattle-eye family. Its species are resident in Africa south of the Sahara. They were previously classed as a subfamily of the Old World flycatcher family, Muscicapidae. They are small stout insect-eating birds, usually found in open forests or bush. The nest is a small neat cup low in a tree or bush. They hunt by flycatching, or by taking prey from the ground like a shrike. ''Batis'' species are strikingly patterned, typically with a grey crown, black eye mask, dark back, and paler underparts, often with a coloured or black breast band and white on the throat which contrasts strongly with the black eye stripe. Male and female plumages usually differ. The song is typically a descending triple whistle. Taxonomy The genus ''Batis'' was introduced by the German zoologist Friedrich Boie in 1833. The type species was subsequently designated as the Cape batis. The name of the genus is from the Ancient Greek ''bati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Congener (biology)
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] |

Shrike
Shrikes () are passerine birds of the family Laniidae. The family is composed of 34 species in four genera. The family name, and that of the largest genus, '' Lanius'', is derived from the Latin word for "butcher", and some shrikes are also known as butcherbirds because of their feeding habits. The common English name shrike is from Old English , alluding to the shrike's shriek-like call. Distribution, migration, and habitat Most shrike species have a Eurasian and African distribution, with just two breeding in North America (the loggerhead and northern shrikes). No members of this family occur in South America or Australia, although one species reaches New Guinea. The shrikes vary in the extent of their ranges, with some species, such as the great grey shrike, ranging across the Northern Hemisphere; to the Newton's fiscal, which is restricted to the island of São Tomé. They inhabit open habitats, especially steppe and savannah. A few species of shrikes are forest dweller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moxico (province)
Moxico (Portuguese spelling) or Moshiko (Bantu spelling) is the largest province of Angola. It has an area of , and covers 18% of the landmass of Angola. The province has a population of 758,568 (2014 census) and a population density of approximately 3.4 residents per km² (8.8/sq mi), making it one of the most sparsely populated areas of Angola. The population of the province is in flux; displaced residents have slowly returned to Moxico since the end of the Angolan Civil War in 2002. The war left Moxico as one of the most landmine-contaminated places in the world. The governor of the province is Gonçalves Manuel Muandumba. Luena is the capital of the Moxico Province, and is located from the Angolan capital of Luanda. History Moxico Province was the scene of much guerrilla fighting during the Angolan Civil War. Its long border with Zambia at the east of the province was a base of operations for UNITA and MPLA. As a result, Moxico Province saw many raids by the military of S ...

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 ...
