Eastern Black-headed Batis
The eastern black-headed batis (''Batis minor'') is a passerine bird in the family Platysteiridae from eastern Africa. It was formerly treated as conspecific with the western black-headed batis. Taxonomy The eastern black-headed batis was described by the German ornithologist Carlo von Erlanger in 1901 who considered the taxon as a subspecies of the grey-headed batis (''Batis orientalis'') and introduced the trinomial name ''Batis orientalis minor''. Two subspecies are recognised: * ''B. m. minor'' Erlanger, 1901 – southern Somalia * ''B. m. suahelica'' Neumann, 1907 – southeastern Kenya and eastern Tanzania Description The eastern black-headed batis is in length and weighs . It is a small, stocky, rather restless, flycatcher like bird with a white, black and grey plumage. The forehead, crown and nape are blackish grey with a white supercilium and loral spot, the mask is glossy bluish black and there is a white spot on the nape. The mantle and back are dark grey with a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carlo Von Erlanger
Carlo von Erlanger (5 September 1872 – 4 September 1904) was a German ornithologist and explorer born in Ingelheim am Rhein. He was a cousin to musicologist Rodolphe d'Erlanger (1872-1932). ''(See: Erlanger family tree).'' He studied ornithology at the University of Lausanne, and performed wildlife studies in the Tunisian desert from 1893 to 1897. On his return to Europe he continued his studies at Cambridge and Berlin. In 1900 and 1901 with Oscar Rudolph Neumann, he went to East Africa (what is now Ethiopia and Somalia) and investigated and collected many thousands of insect and avian specimens. Erlanger died in an automobile accident in Salzburg on 4 September 1904, one day shy of his 32nd birthday. Erlanger is credited with naming 40 new ornithological taxa, and has several zoological species named after him, such as: * Erlanger's lark, ''Calandrella erlangeri'' () *'' Ptychadena erlangeri'' (), an Ethiopian frog *''Lamprophis erlangeri'' , an Ethiopian snake * Erlanger’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 passeri ...

Platysteiridae
Platysteiridae is a family of small, stout passerine birds of the African tropics. The family contains the wattle-eyes, batises and shrike-flycatchers. They were previously classed as a subfamily of the Old World flycatchers, Muscicapidae. These insect-eating birds are usually found in open forests or bush. They hunt by flycatching, or by taking prey from the ground like a shrike. The nest is a small, neat cup, placed low in a tree or bush. Distribution and habitat The Platysteiridae are arboreal birds, primarily of the woodlands and forests of sub-Saharan Africa. The family is restricted to mainland Africa and its offshore islands. The shrike-flycatchers and genus ''Dyaphorophyia'' are inhabitants of dense forest, while the rest of the wattle-eyes are found in woodland, and the batises range across all wooded habitats except the densest forests of the Congo Basin. The pririt and pygmy batis survive in very arid environments with some cover, and the white-fronted wattle-eye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
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] |
Western Black-headed Batis
The western black-headed batis (''Batis erlangeri'') or Von Erlanger's batis, is a species of passerine bird in the wattle-eye family Platysteiridae.Louette, M. (2019)"Western Black-headed Batis (''Batis erlangeri'')" In: del Hoyo, J., Elliott, A., Sargatal, J., Christie, D. A. & de Juana, E. (eds.). ''Handbook of the Birds of the World Alive''. Lynx Edicions, Barcelona. Retrieved 26 November 2019. It is found over an extensive area of central Africa. Its natural habitats are subtropical or tropical dry forests and moist savanna. It was formerly treated as conspecific with the eastern black-headed batis (''Batis minor'').

Trinomial Name
In biology, trinomial nomenclature refers to names for taxa below the rank of species. These names have three parts. The usage is different in zoology and botany. In zoology In zoological nomenclature, a trinomen (), trinominal name, or ternary name refers to the name of a subspecies. Examples are ''Gorilla gorilla gorilla'' ( Savage, 1847) for the western lowland gorilla (genus ''Gorilla'', species western gorilla), and ''Bison bison bison'' (Linnaeus, 1758) for the plains bison (genus '' Bison'', species American bison). A trinomen is a name with three parts: generic name, specific name and subspecific name. The first two parts alone form the binomen or species name. All three names are typeset in italics, and only the first letter of the generic name is capitalised. No indicator of rank is included: in zoology, subspecies is the only rank below that of species. For example: "''Buteo jamaicensis borealis'' is one of the subspecies of the red-tailed hawk (''Buteo jamaicensis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juniper
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of West Asia, western, Central Asia, central and South Asia, southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female Conifer cone, seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form Juniper berry, a&n ...

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 ''batis' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
