White-throated Robin-chat
The white-throated robin-chat or white-throated robin (''Cossypha humeralis'') is a species of bird in the family Muscicapidae. It is endemic to Botswana, Eswatini, Mozambique, South Africa, and Zimbabwe. Its natural habitats are dry savannah and subtropical or tropical dry shrubland. Habitat The white-throated robin-chat is found in dry savannah woodland and shrubland. Behaviour The white-throated robin-chat is mainly insectivorous but also eats small vertebrates and some plant material. Its diet includes beetles, termites, ants, crickets, caterpillars, bugs, spiders and millipedes. It also consumes the fruits of the woolly caper-bush (''Capparis tomentosa''), the tassel-berry (''Antidesma venosum''), the sand raisin (''Grewia microthyrsa''), the magic guarrie (''Euclea divinorum'') and the dune guarrie (''Euclea racemosa'').

Andrew Smith (zoologist)
Sir Andrew Smith (3 December 1797 – 11 August 1872) was a British surgeon, explorer, ethnologist and zoologist. He is considered the father of zoology in South Africa having described many species across a wide range of groups in his major work, ''Illustrations of the Zoology of South Africa''. Smith was born in Hawick, Roxburghshire. He qualified in medicine at the University of Edinburgh obtaining an M.D. degree in 1819, having joined the Army Medical Services in 1816. South Africa 1820–1837 In 1820 he was ordered to the Cape Colony and was sent to Grahamstown to supervise the medical care of European soldiers and soldiers of the Cape Corps. He was appointed the Albany district surgeon in 1822 and started the first free dispensary for indigent patients in South Africa. He led a scientific expedition into the interior and was able to indulge in his interests of natural history and anthropology. On several occasions, he was sent by governors on confidential missions to vis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Birds Of Southern 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 rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cossypha
''Cossypha'' are small insectivorous birds, with most species called robin-chats. They were formerly in the thrush family Turdidae, but are now more often treated as part of the Old World flycatcher Muscicapidae. These are African woodland dwelling species, but some have become adapted to sites around human habitation. The name ''Cossypha'' for the genus was introduced by the Irish zoologist Nicholas Aylward Vigors in 1825. The word comes from the Classical Greek ''kossuphos'' for a blackbird or thrush. The genus contains the following species: * Mountain robin-chat, ''Cossypha isabellae'' * Archer's ground robin, ''Cossypha archeri'' * Olive-flanked ground robin, ''Cossypha anomala'' * Cape robin-chat, ''Cossypha caffra'' * White-throated robin-chat, ''Cossypha humeralis'' * Grey-winged robin-chat, ''Cossypha polioptera'' * Blue-shouldered robin-chat, ''Cossypha cyanocampter'' * Rüppell's robin-chat, ''Cossypha semirufa'' * White-browed robin-chat, ''Cossypha heuglini'' ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-chested Cuckoo
The red-chested cuckoo (''Cuculus solitarius'') is a species of cuckoo in the family Cuculidae. It is a medium-sized bird found in Africa south of the Sahara. In Afrikaans, it is known as "Piet-my-vrou", after its call. Description The red-chested cuckoo is a medium-size cuckoo about in length. The male has slate-grey upper parts, pale grey throat and sides of head and dark grey tail tipped with white. The breast is rufous or cinnamon, often with barring, and the belly is creamy-white or pale buff. The female is similar but the colour of the breast is duller and with variable amounts of barring.

Brood Parasite
Brood parasites are animals that rely on others to raise their young. The strategy appears among birds, insects and fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, usually using egg mimicry, with eggs that resemble the host's. The evolutionary strategy relieves the parasitic parents from the investment of rearing young. This benefit comes at the cost of provoking an evolutionary arms race between parasite and host as they coevolve: many hosts have developed strong defenses against brood parasitism, such as recognizing and ejecting parasitic eggs, or abandoning parasitized nests and starting over. It is less obvious why most hosts do care for parasite nestlings, given that for example cuckoo chicks differ markedly from host chicks in size and appearance. One explanation, the mafia hypothesis, proposes that parasitic adults retaliate by destroying host nests where rejection has occurred; there is ...

Euclea Racemosa
''Euclea racemosa'' (the sea guarrie or dune guarrie) is a small to medium-sized evergreen tree that is indigenous to the Indian Ocean coast of Africa from Egypt to South Africa, as well as in Comoros, Oman and Yemen. ''Euclea racemosa'' has leathery foliage that can be exceptionally even and dense - making it an ideal plant for hedges. A dioecious tree (male and female flowers on separate trees), it produces small white flowers, which are followed by red, purple and black fruits that attract birds. The berries are used locally to make "Guarrie vinegar". The name guarrie appears to derive from the local Khoe language, in which it is spelled gwarri.

Grewia Microthyrsa
''Grewia'' is a large flowering plant genus in the mallow family (biology), family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group. Formerly, Grewia was placed in either the family Tiliaceae or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of ''Grewia'' and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, ''Grewia'' is in the subfamily Grewioideae and therein the tribe (biology), tribe Grewieae, of which it is the type genus. The genus was named by Carl Linnaeus, in honor of the botanist Nehemiah Grew (1641-1712) from England. Grew was one of the leading plant anatomists and microscope researchers of his time, and his study of pollen laid the groundwork for modern-day palynology. Ecology and uses Several Lepidoptera caterpillars are found to feed on ''Grewia'' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
