White-tailed Shrike
The white-tailed shrike (''Lanioturdus torquatus'') is a small passerine bird from the family wattle-eye, Platysteiridae. It is also known as the chatshrike or ground batis. It occurs only in western Angola and Namibia in thorn scrub. It forages from ground level, where it hops about in large bounds and upright posture, to 25m above ground, scanning for insects. The very short tail, with a small black mark at the tip of the central two feathers, is always carried down, never sticking up. Its range of calls includes loud ringing territorial whistles. This curious bird, which some consider to have close affinities with the batis (bird), batises and others the bushshrikes, was discovered in 1837 by James Edward Alexander in the Naukluft Mountains of Namibia. Waterhouse subsequently described it in 1838, the name ''Lanioturdus'' ('shrike-thrush') reflecting the uncertainty of its classification, and ''torquatus'' denoting 'collared'. The sexes have a similar appearance. It is a comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Robert Waterhouse
George Robert Waterhouse (6 March 1810 – 21 January 1888) was an English natural history, naturalist. He was a keeper at the department of geology and later curator of the Zoological Society of London's museum. Early life George was born in Somers Town to James Edward Waterhouse and Mary Newman. His father was a solicitor's clerk and an amateur entomologist. He was the brother of Frederick George Waterhouse, who also became a zoologist. George went to school at Koekelberg, near Brussels. He returned to England in 1824 and worked as an apprentice to an architect. Part of the work was in designing the garden of Charles Knight in the Vale of Health, Hampstead and the ornamentation for St. Dunstan's Church. Natural history George became interested in entomology through his father and he founded the Entomological Society of London along with Frederick William Hope in 1833 with himself as honorary curator. He became its president in 1849–50. He wrote articles for Knight's ''P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Wattle-eye
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 fav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bushshrike
The bushshrikes are smallish passerine birds. They were formerly classed with the true shrikes in the family Laniidae, but are now considered sufficiently distinctive to be separated from that group as the family Malaconotidae, a name that alludes to their fluffy back and rump feathers. Like their shrike-like relatives, the helmetshrikes, the bushshrikes have arisen in Africa in relatively recent times. The family is endemic to sub-Saharan Africa but completely absent from Madagascar, where the vangas are their closest relatives. They are found in scrub or open woodland, and less often in marshes, Afromontane or tropical forest. They are similar in habits to shrikes, hunting insects and other small prey from a perch on a bush. Although similar in build to the shrikes, these tend to be either colourful species or largely black; some species are quite secretive. Some bushshrikes have flamboyant displays. The male puffbacks puff out the loose feathers on their rump and lower back ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Edward Alexander
General Sir James Edward Alexander (16 October 1803 – 2 April 1885) was a Scottish traveller, author and soldier in the British Army. Alexander was the driving force behind the placement of Cleopatra's Needle on the Thames Embankment. Background Born in Stirling, he was the eldest son of Edward Alexander of Powis, Clackmannanshire, and his second wife Catherine Glas, daughter of John Glas, Provost of Stirling. The family purchased Powis House near Stirling in 1808 from James Mayne (his uncle by marriage) for £26,500. His father, a banker, had to sell Powis House in 1827 on collapse of the Stirling Banking Company. He received his training in Edinburgh, Glasgow, and the Royal Military College, Sandhurst. In 1837, he married Eveline Marie Mitchell, daughter of Col C. C. Mitchell of the Royal Artillery. In 1853, he obtained Westerton House in Bridge of Allan, built in 1803 by Dr John Henderson of the East India Company (a cousin and friend). Here he became an elder of Lo ...

Naukluft Mountains
The Naukluft Mountains (Afrikaans and German: ''Naukluftberge'') are a mountain range in central Namibia. The southern part of the mountain range forms the easternmost part of the Namib-Naukluft National Park. The northern mountains are occupied by privately held farms. They are known for their wildlife, including mountain zebras and leopards. The mountains have many small streams and waterfalls. ''Naukluft'' is the Namibian German rendering of the Afrikaans , meaning "narrow ravine", from ('narrow', cf Dutch ) and ('ravine', cf German ). Geology The Naukluft Mountains are a nappe complex: a stack of rock units which have been transported toward the southeast on a basal thrust fault. The first geological maps and cross-sections of the mountain range were made in the 1930s by Henno Martin and Hermann Korn. The rocks are interbedded sediments, dominated by dolomites, quartzites and shales, deposited in a shallow marine environment in the hinterland of the Damara orogeny betwee ...

Mopane
''Colophospermum mopane'', commonly called mopane, mopani, balsam tree, butterfly tree, or turpentine tree, is a tree in the legume family (Fabaceae), that grows in hot, dry, low-lying areas, in elevation, in the far northern parts of southern Africa. The tree only occurs in Africa and is the only species in genus ''Colophospermum''. Its distinctive butterfly-shaped (bifoliate) leaf and thin seed pod make it easy to identify. In terms of human use it is, together with camel thorn and leadwood, one of the three regionally important firewood trees. Range and habit It is native to Southern Africa, including Southern Angola, Zambia, Southern Malawi, Namibia, Botswana, Zimbabwe, Mozambique and northern South Africa. It grows in alkaline (high lime content) soils which are shallow and not well drained. It also grows in alluvial soils (soil deposited by rivers). Where it occurs, it is often the dominant tree species, frequently forming homogeneous stands. In Northern South Africa and ...

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
