Buphagidae
The oxpeckers are two species of bird which make up the genus ''Buphagus'', and family (biology), family Buphagidae. The oxpeckers were formerly usually treated as a subfamily, Buphaginae, within the starling family, Sturnidae, but molecular phylogenetic studies have consistently shown that they form a separate lineage that is basal (phylogenetics), basal to the sister taxon, sister clades containing the Sturnidae and the Mimidae (mockingbirds, thrashers, and allies). Oxpeckers are endemic to the savanna of Sub-Saharan Africa. Both the English language, English and scientific names arise from their habit of perching on large mammals (both wild and domesticated) such as cattle, zebras, impalas, hippopotamuses, rhinoceroses, and giraffes, eating ticks, small insects, botfly larvae, and other parasites, as well as the animals' blood. The behaviour of oxpeckers towards large mammals was thought to be exclusively Mutualism (biology), mutual, though recent research suggests the rela ...

Red-billed Oxpecker (Buphagus Erythrorhynchus) On Impala (Aepyceros Melampus)
The red-billed oxpecker (''Buphagus erythrorynchus'') is a passerine bird in the oxpecker family, Buphagidae. It is native to the savannah of sub-Saharan Africa, from the Central African Republic east to South Sudan and south to northern and eastern South Africa. Its range overlaps that of the less widespread yellow-billed oxpecker. Distribution The red-billed oxpecker is a native of the savanna of sub-Saharan Africa. It ranges across Ethiopia and Somalia through Kenya, Tanzania, Malawi, and Zambia to southern Africa, Botswana, Zimbabwe, southern Mozambique, and north-eastern South Africa. Description A juvenile oxpecker is darker brown than its parents. Its bill is dark olive at first, but gradually takes on adult colouration after four months. Its flight is strong and direct, and their call is a hissy crackling ''trik-quisss''. Behaviour The red-billed oxpecker nests in tree holes lined with hair plucked from livestock. It lays 2–5 eggs, with three being the average. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-billed Oxpecker
The yellow-billed oxpecker (''Buphagus africanus'') is a passerine bird in the family Buphagidae. It was previously placed in the starling and myna family, Sturnidae. It is native to the savannah of Sub-Saharan Africa from Senegal east to Sudan. It is least common in the extreme east of its range (biology), range where it overlaps with the red-billed oxpecker, despite always dominating that species when feeding. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the yellow-billed oxpecker in his ''Ornithologie'' based on a specimen collected in Senegal. He used the French name ''Le pique-boeuf'' and the Latin ''Buphagus''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial nomenclature, binomial system and are not recognised by the International Commission on Zoological Nomenclature.

Hippopotamus
The hippopotamus ( ; : hippopotamuses or hippopotami; ''Hippopotamus amphibius''), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (''Choeropsis liberiensis'' or ''Hexaprotodon liberiensis''). Its name comes from the ancient Greek for "river horse" (). Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average ...

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 ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus ''Bos''. Adult females are referred to as cows and adult males are referred to as bulls. Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather. They are used as riding animals and draft animals ( oxen or bullocks, which pull carts, plows and other implements). Another product of cattle is their dung, which can be used to create manure or fuel. In some regions, such as parts of India, cattle have significant religious significance. Cattle, mostly small breeds such as the Miniature Zebu, are also kept as pets. Different types of cattle are common to different geographic areas. Taurine cattle are found primarily in Europe and temperate areas of Asia, the Americas, and Australia. Zebus (also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zebra
Zebras (, ) (subgenus ''Hippotigris'') are African equines with distinctive black-and-white striped coats. There are three living species: the Grévy's zebra (''Equus grevyi''), plains zebra (''E. quagga''), and the mountain zebra (''E. zebra''). Zebras share the genus ''Equus'' with horses and asses, the three groups being the only living members of the family Equidae. Zebra stripes come in different patterns, unique to each individual. Several theories have been proposed for the function of these stripes, with most evidence supporting them as a deterrent for biting flies. Zebras inhabit eastern and southern Africa and can be found in a variety of habitats such as savannahs, grasslands, woodlands, shrublands, and mountainous areas. Zebras are primarily grazers and can subsist on lower-quality vegetation. They are preyed on mainly by lions, and typically flee when threatened but also bite and kick. Zebra species differ in social behaviour, with plains and mountain zebra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impala
The impala or rooibok (''Aepyceros melampus'') is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus '' Aepyceros'' and tribe Aepycerotini, it was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the common impala, and the larger and darker black-faced impala. The impala reaches at the shoulder and weighs . It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are long. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. Three distinct social groups can be observed: the territorial males, bachelor herds and female herds. The impala is known for two characteristic leaps that constitute an anti-predator strategy. Browsers as well as grazers, impala feed on monocots, dicots, forbs, fruits and acacia pods (whenever available). An annual, three-week-long rut takes place ...

Yellow-headed Caracara
The yellow-headed caracara (''Daptrius chimachima'') is a bird of prey in the family Falconidae. It is found in tropical and subtropical South America and the southern portion of Central America. Unlike the falcons in the same family, the caracara is not a fast-flying aerial hunter, but is rather sluggish and often obtains food by scavenging. Taxonomy When Louis Jean Pierre Vieillot first described the yellow-headed caracara in 1816, he gave it the scientific name ''Polyborus chimachima'', putting it in the same genus as the crested caracaras. In 1824, German naturalist Johann Baptist von Spix created the genus ''Milvago'' for this species and the closely related chimango caracara. Formerly, the yellow-headed caracara was classified in the genus ''Milvago'' together with the Chimango caracara (then ''Milvago chimango''). However, molecular studies from 2012 showed that the genus ''Milvago'' is not monophyletic. These two species were therefore reclassified together with variou ...

Rhinoceros
A rhinoceros (; ; ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm), protective skin formed from layers of collagen positioned in a lattice structure. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths; they rely instead on their lips to pl ...

Giraffe
The giraffe is a large African hoofed mammal belonging to the genus ''Giraffa''. It is the tallest living terrestrial animal and the largest ruminant on Earth. Traditionally, giraffes were thought to be one species, ''Giraffa camelopardalis'', with nine subspecies. Most recently, researchers proposed dividing them into up to eight extant species due to new research into their mitochondrial and nuclear DNA, as well as morphological measurements. Seven other extinct species of ''Giraffa'' are known from the fossil record. The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its spotted coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. Its scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannahs and woodlands. Their food source is leaves, frui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
