Cape Crow
The Cape crow or black crow (''Corvus capensis'') is slightly larger (48–50 cm in length) than the carrion crow and is completely black with a slight gloss of purple in its feathers. It has proportionately longer legs, wings and tail too and has a much longer, slimmer bill that seems to be adapted for probing into the ground for invertebrates. The head feathers have a coppery-purple gloss and the throat feathers are quite long and fluffed out in some calls and displays. Distribution and habitat This species occurs in two large separate regions of the African continent. One form ranges from the Cape at the southern tip of Africa up to southern Angola and across to the east coast of Mozambique. The other population occurs in a large area from South Sudan, Ethiopia, Tanzania and Kenya in central east Africa. The more northern population is on average slightly smaller than the southern. It inhabits open grassland, moorland, agricultural areas with some trees or woodland in the v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Martin Lichtenstein
Martin Hinrich Carl Lichtenstein (10 January 1780 – 2 September 1857) was a German physician, explorer, botanist and zoologist. Biography Born in Hamburg, Lichtenstein was the son of Anton August Heinrich Lichtenstein. He studied medicine at Jena and Helmstedt. Between 1802 and 1806 he travelled in southern Africa, becoming the personal physician of the Governor of the Cape of Good Hope. In 1811 he published ''Reisen im südlichen Afrika : in den Jahren 1803, 1804, 1805, und 1806''; as a result, he was appointed professor of zoology at the University of Berlin in 1811, and appointed director of the Berlin Zoological Museum in 1813. In 1829, he was elected a foreign member of the Royal Swedish Academy of Sciences. He died after he had a stroke at sea travelling aboard a steamer from Korsør to Kiel. Legacy Lichtenstein was responsible for the creation of Berlin's Zoological Gardens in 1841, when he persuaded King Frederick William IV of Prussia to donate the grounds of h ...

Carrion Crow
The carrion crow (''Corvus corone'') is a passerine bird of the family Corvidae and the genus ''Corvus'' which is native to western Europe and the eastern Palearctic. Taxonomy and systematics The carrion crow was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', and it still bears its original name of ''Corvus corone''. The binomial name is derived from the Latin , "raven", and Greek , "crow". The hooded crow, formerly regarded as a subspecies, has been split off as a separate species, and there is some discussion whether the eastern carrion crow (''C. c. orientalis'') is distinct enough to warrant specific status; the two taxa are well separated, and it has been proposed they could have evolved independently in the wetter, maritime regions at the opposite ends of the Eurasian landmass.Madge, Steve & Burn, Hilary (1994): ''Crows and jays: a guide to the crows, jays and magpies of the world''.

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Corncob
A corncob, also called corn cob, cob of corn or corn on the cob, is the central core of an ear of corn (also known as maize). It is the part of the ear on which the kernels grow. The ear is also considered a "cob" or "pole" but it is not fully a "pole" until the ear is shucked, or removed from the plant material around the ear. Young ears, also called baby corn, can be consumed raw, but as the plant matures the cob becomes tougher until only the kernels are edible. When harvesting corn, the corncob may be collected as part of the ear (necessary for corn on the cob), or instead may be left as part of the corn stover in the field. The innermost part of the cob is white and has a consistency similar to foam plastic. Uses Corncobs find use in the following applications: * Industrial source of the chemical furfural * Fiber in fodder for ruminant livestock (despite low nutritional value) Other applications include: * Bedding for animals – cobs absorb moisture and provide ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Corvus
''Corvus'' is a widely distributed genus of medium-sized to large birds in the family Corvidae. It includes species commonly known as crows, ravens and Rook (bird), rooks. The species commonly encountered in Europe are the carrion crow, the hooded crow, the common raven and the rook (bird), rook; those discovered later were named "crow" or "raven" chiefly on the basis of their size, crows generally being smaller. The genus name is Latin for "crow". The List of Corvus species, 45 or so members of this genus occur on all temperate continents except South America, and several islands. The ''Corvus'' genus makes up a third of the species in the family Corvidae. The members appear to have evolved in Asia from the corvid stock, which had evolved in Australia. The collective noun, collective name for a group of crows is a "flock" or a "murder". Recent research has found some crow species capable of not only Tool use by animals, tool use, but also tool construction. Crows are now consi ...

Birds Of East 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] |
