Celtis Africana
''Celtis africana'', the white stinkwood, is a deciduous tree in the family Cannabaceae. Its habit ranges from a tall tree in forest to a medium-sized tree in bushveld and open country, and a shrub on rocky soil. It occurs in Yemen and over large parts of Africa south of the Sahara. It is a common tree in the south and east of southern Africa, where the odour given off by freshly-cut green timber is similar to that of ''Ocotea bullata'' or Black Stinkwood. Description Habit Growing as an individual tree in the open and under favourable conditions, ''Celtis africana'' becomes a tree of medium height, typically up to 12 m or so. It then usually forms a dense, hemispherical canopy. The bole of a mature tree then is thick and buttressed, often forked fairly near the ground. In forest it may grow up to 25 m tall, with a single, clean bole, though such large specimens usually are more or less buttressed too. In an exposed, rocky position it may be a bonsai-like small shrub. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicolaas Laurens Burman
Nicolaas Laurens Burman (27 December 1734 – 11 September 1793) was a Dutch botanist. He was the son of Johannes Burman (1707–1780). He succeeded his father to the chair of botany at the Athenaeum Illustre of Amsterdam., and at the Hortus Botanicus (Amsterdam), Hortus Botanicus. He continued the correspondence with Carl Linnaeus, joining him at the University of Uppsala in 1760. He is the author of numerous works including ''Specimen botanicum de geraniis'' (1759) and ''Flora Indica'' (1768) which was later completed by Johann Gerhard Koenig (1728–1785).

Drupe
In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pit'', ''stone'', or '' pyrena'') of hardened endocarp with a seed (''kernel'') inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, lignified stone is derived from the ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a different definition of ''berry''. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes. Flowering plants that produce drupes include coffee, jujube, mango, oli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chorister Robin-chat
The chorister robin-chat (''Cossypha dichroa'') (previously known as the chorister robin) is a species of bird in the family Muscicapidae. It is found in South Africa and Eswatini. Its distribution stretches from the southern Western Cape through the Eastern Cape, KwaZulu-Natal, Swaziland and Mpumalanga to northern Limpopo. Its natural habitat is evergreen forests, especially in the mist belt region. This is a large robin-chat, about 20 cm in length. The chorister robin-chat is identified by its dark upperparts (the ear coverts and lores are slightly darker than the rest of the face, head, neck and back) and yellow-orange underparts. It has no white eye stripe. Juveniles have a sooty, mottled tawny-buff above and below and its tail is red-orange with a dark centre. The chorister robin-chat is generally solitary. This robin-chat skulks in dense foliage in the forest canopy. In winter it may forage on ground, but usually gleans insects from leaves. It also follows other fauna ...

Cape Robin-chat
The Cape robin-chat (''Cossypha caffra'') is a small passerine bird of the Old World flycatcher family Muscicapidae. It has a disjunct range from South Sudan to South Africa. The locally familiar and confiding species has colonized and benefited from a range of man-altered habitats, including city suburbs and farmstead woodlots. It is an accomplished songster like other robin-chats, but is rather less colourful than most, and frequents either drier settings or higher altitudes. It forages in the proximity of cover, in the open or in fairly well-lit environments. Its distribution resembles that of the karoo–olive complex of thrushes, but it prefers the bracken- briar fringes of Afromontane forest, and does not enter far into forest proper. It is altitudinally segregated from the red-capped robin-chat, and is less of a skulker. Range and movements The Cape robin-chat occurs from South Sudan (mainly Imatong Mts, above 1,600 m) southwards to Uganda, the DRC (1,800 m – 3 ...

Karoo Thrush
The Karoo thrush (''Turdus smithi''), also known as Smith's thrush, is a member of the thrush family in Africa. It has traditionally been considered a subspecies of the olive thrush (with which it is known to hybridize), but is increasingly treated as a separate species. The specific name honours the Scottish military surgeon and zoologist Sir Andrew Smith. Description This medium-sized bird has a length of about 24 cm. It has a wing length between 117 and 131 mm, a culmen length between 20 and 24 mm and a tarsus length between 30.0 and 34.5 mm. It can reach a mass of at least 86 g. It differs from the olive thrush by its longer, entirely yellow bill, its longer wings, and its greyer flanks. Range It occurs in South Africa, where it is present in Little Namaqualand, the Karoo and Northern Cape, Free State, Gauteng, Limpopo, Mpumalanga and parts of the North West Province.

Crested Barbet
The crested barbet (''Trachyphonus vaillantii'') ('trachys'=rough, 'phone'=voice, sound') is a sub-Saharan bird in the Lybiidae family. Its specific name commemorates François Levaillant, a famed French naturalist. Description With its thick bill and very colourful plumage the crested barbet is unmistakable. This small bird has a speckled yellow and red face with a small black crest. The belly is yellow with red speckles, wings are black with white specks and it has a broad black band on its neck. Yellow head and body with black and white feathers, red markings on end of body, its colour blends well in the bush. They have a distinct trill. Diet The crested barbet feeds on insects, other birds' eggs and fruits and sometimes mice. Breeding They nest in a hole in a tree or a log in a suburban garden. They are monogamous and territorial during breeding. Territory size varies according to their habitat. One to five eggs are laid at daily intervals between September and December. ...

Colius
''Colius'' is a genus of mousebirds in the family Coliidae. The four species are widely distributed in Africa. Two other African mousebirds are placed in the genus ''Urocolius''. The genus ''Colius'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the white-backed mousebird (''Colius colius'') as the type species. The genus contains the following four species: A fossil species, ''Colius hendeyi'', was described from Early Pliocene remains found at Langebaanweg in South Africa. Some Miocene taxa from France were previously assigned to ''Colius''. Of these, only the Middle Miocene ''"Colius" palustris'' might plausibly belong there,Mlíkovský (2002) but it is more often separated in ''Necrornis''. In younger lineages like Passeriformes, extant genera (e.g. '' Menura'' and ''Orthonyx'') were around by then, though it must be remembered that simply because two taxa are of same taxonomic rank they do not need to be of the same age. All that can be sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple-crested Turaco
The purple-crested turaco (''Gallirex porphyreolophus'') or, in South Africa, the purple-crested loerie, is a species of bird in the clade Turaco with an unresolved phylogenetic placement. Initial analyses placed the purple-crested turaco in the family Musophagidae'','' but studies have indicated that these birds do not belong to this family and have been placed in the clade of Turacos with an unresolved phylogeny. It is the National Bird of the Kingdom of Eswatini, and the crimson flight feathers of this and related turaco species are important in the ceremonial regalia of the Swazi royal family. Description This bird has a purple coloured crest above a green head, a red ring around their eyes, and a black bill. The neck and chest are green and brown. The rest of the body is purple, with red flight feathers. Purple-crested turacos are considered to be large frugivores that are known to carry cycad seeds from various plant species long distances from feeding to nesting sites. Af ...

Knysna Lourie
The Knysna turaco (''Tauraco corythaix''), or, in South Africa, Knysna loerie, is a large turaco, one of a group of African musophagidae birds. It is a resident breeder in the mature evergreen forests of southern and eastern South Africa, and Swaziland. It was formerly sometimes considered to be a subspecies of the green turaco of West Africa. The Livingstone's and Schalow's turacos were once considered subspecies. This species lays two eggs in a shallow platform nest made from sticks and placed in a tree or clump of creepers. Within its range, this is an unmistakable bird, although often inconspicuous in the treetops. It is 40–42 cm long, including a long tail. The small but thick orange-red bill and a white line just under the eye contrast with the mainly green plumage. It has a tall green crest, which is tipped with white. The eye is brown and the eye-ring deep red. In flight, Knysna turaco shows conspicuous crimson primary flight feathers. Sexes are similar, but juven ...

Cape Parrot
The Cape parrot (''Poicephalus robustus'') or Levaillant's parrot is a large, temperate forest dwelling parrot of the genus ''Poicephalus'' endemic to South Africa. It was formerly grouped as a subspecies along with the savanna-dwelling brown-necked parrot (''Poicephalus fuscicollis'') and grey-headed parrot (''P. f. suahelicus''), but is now considered a distinct species. Taxonomy The Cape parrot was described in 1781 by the English ornithologist John Latham under the English name, the "robust parrot". When in 1788 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's ''Systema Naturae'', he included the Cape parrot with a short description, coined the binomial name ''Psittacus robustus'' and cited Latham's work. The type locality is South Africa. The Cape parrot is now placed with nine other species in the genus ''Poicephalus'' that was introduced by the English naturalist William John Swainson in 1837. The genus name is from the Ancient Greek ''p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
