Double-banded Sandgrouse
The double-banded sandgrouse (''Pterocles bicinctus'') is a species of predominantly terrestrial, or ground-dwelling (though not flightless), bird in the family Pteroclidae. It is found in arid parts of southern Africa. Subspecies There are three subspecies: ''P. b. ansorgei'' is found in the southwest of Angola; ''P. b. bicinctus'' is found in Namibia, Botswana and the northwest of Cape Province, South Africa; ''P. b. multicolor'' is found in Zambia, Malawi, Mozambique and Transvaal. These sandgrouse have been observed in and around the Okavango Delta in Botswana. Description A moderately-sized, quail-like bird with a plump body, the double-banded sandgrouse has a small, almost pigeon-like head with a long pair of wings and tail. The general colour of the plumage is light brown, with darker mottling and rows of whitish specks; the male is distinguished by having a conspicuous black-and-white band on his forehead, with a chestnut-coloured throat that is delineated by anot ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch patrician, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), illustrated by Pauline Rifer de Courcelles, Pauline Knip. He wrote ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna jap ...

Pigeon
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 small heads, relatively short necks and slender bills that in some species feature fleshy ceres. They feed largely on plant matter, feeding on seeds ( granivory), fruit ( frugivory), and foliage ( folivory). In colloquial English, the smaller species tend to be called "doves", and the larger ones "pigeons", although the distinction is not consistent, and there is no scientific separation between them. Historically, the common names for these birds involve a great deal of variation. The bird most commonly referred to as "pigeon" is the domestic pigeon, descendant of the wild rock dove, which is a common inhabitant of cities as the feral pigeon. Columbidae contains 51 genera divided into 353 species. The family occurs worldwide, often in close proximity to humans, but the greatest diversity is in the Indomalayan and Australasi ...

Datura Innoxia
''Datura innoxia'' (often spelled ''inoxia''), known as pricklyburr, recurved thorn-apple, downy thorn-apple, Indian-apple, lovache, moonflower, nacazcul, toloatzin, toloaxihuitl, tolguache or toloache, is a species of flowering plant in the family Solanaceae. It is more rarely called sacred datura, a common name which is applied more often to the closely related ''Datura wrightii''. It is native to the Southwestern United States, Central and South America, and introduced in Africa, Asia, Australia and Europe. The scientific name is often cited as ''D. innoxia''. When English botanist Philip Miller first described the species in 1768, he misspelled the Latin word ''innoxia'' (inoffensive) when naming it ''D. inoxia''. The name ''Datura meteloides'' was for some time erroneously applied to some members of the species, but that name has now been abandoned. Description ''Datura innoxia'' is a tuberous-rooted subshrub that typically reaches a height of 0.6 to 1.5 metres. Its stems ...

Cyperus
''Cyperus'' is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Description They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to deep. The species vary greatly in size, with small species only tall, while others can reach in height. Common names include ''papyrus sedges'', ''flatsedges'', ''nutsedges'', ''umbrella-sedges'', ''galingales'', and ''zozoro'' (from Malagasy). The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Ecology ''Cyperus'' species are eaten by the larvae of some Lepidoptera species, including ''Chedra microstigma''. They also provide ...

Tephrosia
''Tephrosia'' is a genus of flowering plants in the family Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions. The generic name is derived from the Greek word τεφρος (''tephros''), meaning "ash-colored," referring to the greyish tint given to the leaves by their dense trichomes. Hoarypea is a common name for plants in this genus, along with goat's rue and devil's shoestring. Uses Many species in the genus are poisonous, particularly to fish, for their high concentration of rotenone. The black seeds of ''Tephrosia'' species have historically been used by indigenous cultures as fish toxins.Hugh Scott, ''In the High Yemen'', London 1942, p. 238, note C.NTFlora Northern Territory Flora online:''Flora of the Darwin Region: Fabaceae.''Retrieved 10 June 2018 In the last century, several ''Tephrosia'' species have been studied in connection with the use of rotenone as an insecticide and pesticide. ...

Requienia (plant)
''Requienia'' is a genus of flowering plants in the family Fabaceae. It includes two species of herbs native to Botswana, Caprivi Strip, Namibia, and Zambia, and the Cape Provinces, Free State and Northern Provinces of South Africa. They grow on sand in dry tropical wooded grassland, shrubland, and bushland in the southern Zambezian region and the Kalahari and Highveld regions. The genus name of ''Requienia'' is in honour of Esprit Requien (1788–1851), who was a French naturalist, who made contributions in the fields of conchology, palaeontology and especially botany.

Acacia
''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from Koine Greek (), a term used in antiquity to describe a preparation extracted from '' Vachellia nilotica'', the original type species. Several species of ''Acacia'' have been introduced to various parts of the world, and two million hectares of commercial plantations have been established. Description Plants in the genus ''Acacia'' are shrubs or trees with bipinnate leaves, the mature leaves sometimes reduced to phyllodes or rarely absent.

Pterocles Bicinctus -Northern Cape, South Africa -male-8
''Pterocles '' is a genus of near passerine birds in the sandgrouse family. It includes all the species in the family except for two central Asian species in ''Syrrhaptes''. These sandgrouse have small, pigeon-like heads and necks, but sturdy compact bodies. They have long pointed wings and sometimes tails. Their legs are feathered down to the toes, but unlike species of the genus ''Syrrhaptes'' the toes are not feathered. ''Pterocles'' species have a fast direct flight, and flocks fly to watering holes at dawn and dusk. Two to three eggs are laid directly on the ground. They are buff or greenish with cryptic markings. All species are resident. Taxonomy The genus ''Pterocles'' was introduced in 1815 by the Dutch zoologist Coenraad Jacob Temminck. The type species was subsequently designated by the English zoologist George Robert Gray as the pin-tailed sandgrouse. The genus name combines the Ancient Greek ''pteron'' meaning "wing" with ''-klēs'' meaning "notable" or "splendid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namaqua Sandgrouse
The Namaqua sandgrouse (''Pterocles namaqua''), is a species of ground-dwelling bird in the sandgrouse family. It is found in arid regions of south-western Africa. Taxonomy The Namaqua sandgrouse was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the grouse like birds in the genus '' Tetrao'' and coined the binomial name ''Tetrao namaqua''. Gmelin based his description on the "Namaqua grous" that had been described in 1783 by the English ornithologist John Latham in his ''A General Synopsis of Birds''. The Namaqua sandgrouse is now placed with 13 other species in genus '' Pterocles'' that was introduced in 1815 by the Dutch zoologist Coenraad Jacob Temminck. The genus name combines the Ancient Greek ''pteron'' meaning "wing" with ''-klēs'' meaning "notable" or "splendid".

Burchell's Sandgrouse
Burchell's sandgrouse (''Pterocles burchelli'') is a species of bird in the family Pteroclidae. It is found in arid and semi-arid regions of southern Africa. The name of this bird commemorates the English naturalist William John Burchell. Description Burchell's sandgrouse is a plump bird about the size of a pigeon with a small head and short legs. The body is light brown, mottled with darker shades and white speckles. In males, the eye is surrounded by bare yellow skin and the cheeks and throat are pale grey. The male grows to about long and the female is a little smaller. Burchell's sandgrouse is limited by water availability, like many species residing in desert environments. Adult sandgrouse increase gular fluttering and panting for evaporative cooling when approaching the upper critical limit of their thermal neutral zone around 43.8°C. Another adaptation that adult Burchell's sandgrouse have developed is the transport of water in body feathers from a water source back t ...

Mopane
''Colophospermum mopane'', commonly called mopane, mopani, butterfly tree, turpentine tree, or balsam tree, is a tree in the legume family (Fabaceae), that grows in hot, dry, low-lying areas, in elevation, in 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 kidney-shaped/nearly semi-circular legume, seed pod make it easy to identify. Though hard and dense and difficult to work with, it is valued timber in all sorts of construction due to its termite tolerance. Together with Acacia erioloba, camel thorn and Combretum imberbe, leadwood, one of the three regionally important firewood trees, due to the enduring heat, and these woods are also some of the preferred use culinarily for braai. Range and habitat The mopane is found on low-lying ground from (Mozambique) to (Zimbabwe). Mopane ecoregions Native to Southern Africa, its habitat is divided crudely into ...
