They numbered about 250,000 in 1960 as compared to approximately 1.5 million today. [35] In East Africa, the blue wildebeest is the most abundant big game species, both in population and biomass. Also known as the gnu, the wildebeest is a member of the antelope family. The populations of this species are on an increase. The wildebeest is one of the few African antelopes to have extended its range. Fur keeps them warm in cold weather. So can the most deadly snake (the black mamba). Bulls may occupy territories, usually about 100 to 400 m (300 to 1,300 ft) apart, but this spacing varies according to the quality of the habitat. Phosphorus is a crucial element for all life forms, particularly for lactating female bovids. C. taurinus has high shoulders sloping to lower hindquarters, a deep chest, a short… For other uses, see, "Gnu" redirects here. The wildebeest belongs to the family Bovidae and the tribe Alcelaphini. The other is the black wildebeest. The Wildebeest (genus Connochaetes), also called a Gnu, is an ungulate mammal found in Southern Kenya, South Angola to north south Africa. Wildebeests move west toward Lake Victoria, across the grass savanna to the open woodlands, then turn north into the Mara. In 1914, two separate races of the wildebeest were introduced, namely Gorgon a. albojubatus ("Athi white-bearded wildebeest") and G. a. mearnsi ("Loita white-bearded wildebeest"). [54] The main predator of the calves is the spotted hyena. These small territories are about 3,000 square metres (32,000 sq ft; 0.74 acres), with up to 300 territories per 1 square kilometre (0.39 sq mi; 250 acres). They can be found in habitats that vary from overgrazed areas with dense bush to open woodland floodplains. They also provide important products, such as leather, to humans. [37] It is no longer found in Malawi but has been successfully reintroduced into Namibia. They can also spread ticks, lungworms, tapeworms, flies, and paramphistome flukes. Typically, the predators attempt to isolate a young or ill animal and attack without having to worry about the herd. While most tourists are attracted to the wildlife above the ground in a savanna, there is … This area is covered with Blue Wildebeest and Warthog's. The blue wildebeest was first known to westerners in the northern part of South Africa a century later, in the 1800s. They now only occur to any significant degree in East Africa and the central Zambezian region. The estimated price for wildebeest meat was about US$0.47 per 1 kilogram (2.2 lb) around 2008. There are more than 40 species of hoofed mammals living in the savannas. The calves weigh about 21 kg (46 lb) at birth[10] and scramble to their feet within minutes, being able to move with the herd soon afterwards,[32] a fact on which their survival relies. [41], Each year, some East African populations of blue wildebeest have a long-distance migration, seemingly timed to coincide with the annual pattern of rainfall and grass growth. [25], The black wildebeest has been classified as a least-concern species by the International Union for Conservation of Nature in the IUCN Red List. [39], In the Maasai Mara game reserve, a non-migratory population of blue wildebeest had dwindled from about 119,000 animals in 1977 to about 22,000 in 1997. taurinus). They are very fast, agile, and powerful. And they can run as fast as 56 km/h. Its introduction into Namibia has been a success and numbers have increased substantially there from 150 in 1982 to 7,000 in 1992. [20] The earliest fossils of the black wildebeest were found in sedimentary rock in Cornelia in the Orange Free State and dated back about 800,000 years. Large carnivores were rarer still, with only lions remaining after the war. Wildebeest calves can walk within minutes of being born. Wildebeest is Dutch for "wild beast" or "wild cattle" in Afrikaans (bees "cattle"), while Connochaetes derives from the Greek words κόννος, kónnos, "beard",[8] and χαίτη, khaítē, "flowing hair", "mane". Tanzania: Savanna Birds, Wildebeest Migration, and Eastern Arc Mountains Trip Report, April 2015. Wildebeest on african savanna. We examined the landscape-level distribution of groups of blue wildebeest, Connochaetes taurinus, and Burchell's zebra, Equus burchelli, in a … Currently, the reserve has 62 missions: 16 main missions and 32 side missions and 14 warden missions, making the reserve to be the map with the least missions. The blue wildebeest is the bigger of the two species. One study showed, along with other ungulates, wildebeests responded more strongly to the baboon alarm calls compared to the baboon contest calls, though both types of calls had similar patterns, amplitudes, and durations. In East Africa, the blue wildebeest is the most abundant big-game species; some populations perform an annual migration to new grazing grounds, but the black wildebeest is merely nomadic. (Cattle herds, too, were decimated which caused enormous hardship for the traditional herding communities that depended on cattle). Males are larger than females and both have heavy forequarters compared to their hindquarters. The wildebeest , also called the gnu (/njuː/ NEW or /nuː/ NOO), is an antelope in the genus Connochaetes. [57] Illegal hunting is a major conservation concern in many areas, along with natural threats posed by main predators (which include lions, leopards, African hunting dogs, cheetahs and hyenas). The reason for the decline is thought to be the increasing competition between cattle and wildebeest for a diminishing area of grazing land as a result of changes in agricultural practices, and possibly fluctuations in rainfall. Breeding in both takes place over a short period of time at the end of the rainy season and the calves are soon active and are able to move with the herd, a fact necessary for their survival. [19], Blue wildebeest fossils dating back some 2.5 million years ago are common and widespread. [36], The blue wildebeest is native to eastern and southern Africa. A wildebeest can grow to 2.4 meters (8 feet) in length, and weigh up to 270 kilograms (600 pounds). [34] It inhabits open plains, grasslands, and Karoo shrublands in both steep mountainous regions and lower undulating hills at altitudes varying between 1,350 and 2,150 m (4,430 and 7,050 ft). The International Union for Conservation of Nature lists both as least-concern species. [34], The blue wildebeest has also been rated as of least concern. The resulting offspring are usually fertile. Wildebeest often graze in mixed herds with zebra, which gives heightened awareness of potential predators. Join our Partner Program. Show More. As a result, during the rainy season, wildebeest select grazing areas that contain particularly high phosphorus levels. Factors suspected to affect migration include food abundance, surface water availability, predators, and phosphorus content in grasses. It has now been reintroduced to them and also introduced to Namibia, where it has become well established. Blue wildebeest tend to be a dark grey colour with stripes, but may have a bluish sheen. Many have proclaimed that it is made up of a number of different animal parts – forequarters from an ox, hindquarters from an antelope, and mane and tail from a horse. The blue wildebeest is also known as the Brindled Gnu. [32], Not all wildebeest are migratory. Wildebeest females breed seasonally and ovulate spontaneously. The horns of blue wildebeest protrude to the side, then curve downwards before curving up back towards the skull, while the horns of the black wildebeest curve forward then downward before curving upwards at the tips. Despite their bulky bodies, wildebeests don't rank at the top of the food chain in their plains and savanna habitats in Africa. Black Wildebeest are smaller, with horns curving forward and a long white tail, they are exclusively found on open grassland. Grass-grazing wildebeests -- and their calves in particular -- are targets of carnivorous cheetahs, lions and hyenas. Sadly, their more remarkable features are often not known. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black wildebeest changed more as adaptation to its open grassland habitat in the south. However, as a result of widespread hunting, the black wildebeest no longer occupies its historical range or makes migrations, and is now largely limited to game farms and protected reserves. Movies and television shows also feature wildebeests, including Khumba (Mama V), The Wild (Kazar and his minions), All Hail King Julien (Vigman Wildebeest), Phineas and Ferb (Newton the Gnu), The Great Space Coaster (newscaster Gary Gnu), and The Lion King (the wildebeest stampede that resulted in Mufasa's death). [48] In the Serengeti ecosystem, Tanzania, wildebeest may help facilitate the migration of other, smaller-bodied grazers, such as Thomson's gazelles (Eudorcas thomsonii), which eat the new-growth grasses stimulated by wildebeest foraging. Where the black and blue wildebeest share a common range, the two can hybridise, and this is regarded as a potential threat to the black wildebeest. Both males and females have horns, however the males’ horns are larger and joined at the base by a boss-like structure. The vultures consume about 70% of the wildebeest carcasses available. The large herbivores that were dominant before the war — iconic African animals like zebra, wildebeest and hippopotamus — were rare. C. taurinus has high shoulders sloping to lower hindquarters, a deep chest, a short neck, and thin legs. However, in larger aggregations, or small groups living near large herds, survival rates may be over 80%. It has been assigned a membership to the “Ugly 5”, and is an almost comedic figure in the bush. Two Blue wildebeests large antelopes walking in dry grass at the evening in savanna. [19] Today, five subspecies of the blue wildebeest are recognised, while the black wildebeest has no named subspecies. They then begin the return trip to the south. [31] Wildebeest can live more than 40 years, though their average lifespan is around 20 years. The population trend is stable, and their numbers are estimated to be around 1,500,000 – mainly due to the increase of the populations in Serengeti National Park (Tanzania) to 1,300,000. The largest buffalo weighs around 910 kg – just short of a ton! Two species exist: the common wildebeest (Connochaetes taurinus) and the black wildebeest, or white-tailed gnu (C. gnou). Easily recognised by their anvil-shaped head, wildebeest have become something of an icon when the African plains come to mind. In females, blue wildebeest have a shoulder height of 135 cm and weigh 180 kg while black wildebeest females stand 108 cm at the shoulder and weigh 155 kg. Buffalo horns. in Hwange and Etosha National Parks to 35/km2 in Ngorongoro Conservation Area and Serengeti National Park. [11] Others contend the name and its pronunciation in English go back to the word !nu: used for the black wildebeest by the San people. The alarm calls were a response of the baboons to lions, and the contest calls were recorded when a dispute between two males occurred. A savanna is a transitional biome with both grasslands and woodlands that is characterized by a very long dry season. Spot Zebras and Gnus on your Safari in Madikwe [28] This usually occurs between May and July, and birthing usually takes place between January and March, at the start of the wet season. In the Serengeti-Mara ecosystem the animals make a migratory circle each year of 500 to 1,000 miles! [50] The seasonal presence of thousands of migratory wildebeests reduces local lion predation on giraffe calves, resulting in greater survival of giraffes. For most of their lives, wildebeest graze in the grassy savannas and open woodlands of the plains, which straddle the nations of Tanzania and Kenya. They have a gray coat and a black mane as well as a beard that can be black or white. 1 Main Missions 2 Side Mission 2.1 Warden Missions 2.2 Mboweni Missions 2.3 Ospreay Missions 2.4 Maritz Missions 2.5 Brother Missions … Around 80% of the wildebeest occurs in private areas, while the other 20% is confined in protected areas. Cooks preparing the wildebeest carcass usually cut it into 11 pieces. The blue wildebeest is one of 2 species of wildebeest found on the African continent. The Animals tend to migrate to across the savanna, Zebras, gazelles, and Wildebeest look for water while predators like Lions, Cheetahs, and Leopards follow those animals to prey on them, and scavengers as Hyenas and Vultures eat the left overs of the predators. By Dominic Rollinson January 29, 2017 Tanzania Trip Reports. They don’t like the western plateau or the southeastern corner of the map. Metaphases were studied in the male's chromosomes, and very large submetacentric chromosomes were found there, as well, similar to those in the female both in size and morphology. When the rainy season begins again (months later), animals quickly move back to their wet-season ranges. [30] The milk of the female black wildebeest contains a higher protein, lower fat, and lower lactose content than the milk of the blue wildebeest. [50] This female-dominated sex ratio may be due to illegal hunting and human disturbance, with higher male mortality having been attributed to hunting. Another reason is that Zebras and Wildebeests love the open African savannas – in comparison to Kudus or other antelopes that prefer the thicker bush. Background Group dynamics of gregarious ungulates in the grasslands of the African savanna have been well studied, but the trade-offs that affect grouping of these ungulates in woodland habitats or dense vegetation are less well understood. Herd of wildebeest on the savanna in Central Kalahari Game Reserve in Botswana royalty free stock video and stock footage. The calving peak period lasts for 2–3 weeks, and in small subpopulations and isolated groups, mortality of calves may be as high as 50%. While having the appearance of a frenzy, recent research has shown a herd of wildebeest possesses what is known as a "swarm intelligence", whereby the animals systematically explore and overcome the obstacle as one. At the end of the wet season (May or June in East Africa), wildebeest migrate to dry-season areas in response to a lack of surface (drinking) water. A study of these hybrid animals at Spioenkop Dam Nature Reserve in South Africa revealed that many had disadvantageous abnormalities relating to their teeth, horns, and the wormian bones in the skull. [43], Aerial photography has revealed that a level of organisation occurs in the movement of the herd that cannot be apparent to each individual animal; for example, the migratory herd exhibits a wavy front, and this suggests that some degree of local decision-making is taking place. Large-scale migration of tropical savanna herbivores, such as wildebeest (Connochaetes taurinus) and zebra (Equus quagga), are continuing to decline through habitat alteration and hunting. Savannas are home to a wide diversity of animals. [35], Wildebeest provide several useful animal products. They can be between 4 and 5 feet tall and weigh as much as 600 pounds. The blue wildebeest lives in a wide variety of habitats, including woodlands and grasslands, while the black wildebeest tends to reside exclusively in open grassland areas. [28] The most striking morphological differences between the black and blue wildebeest are the orientation and curvature of their horns and the colour of their coats. In fact, the wildebeest is better described as a reliable source of food for the truly menacing predators of the African savanna: lions, cheetahs, wild dogs, and hyenas. It is highly gregarious and superbly adapted for a migratory existence. Spread the Word and Earn! Wildebeest Wildebeest is a large antelope found in acacia savannah plains, most of the woodlands and grasslands of east and South Africa. [59] Wildebeest, however, can also have a negative impact on humans. Lions are zebra’s main enemy but other animals like crocodiles and wildebeest can attack them too. The most acute threat comes from migration barriers, such as fences and roads. Wildebeest usually breed at the end of the rainy season when the animals are well fed and at their peak of fitness. [40] During the rutting season, the males may form temporary territories for a few hours or a day or so, and attempt to gather together a few females with which to mate, but soon they have to move on, often moving ahead to set up another temporary territory. The common wildebeest inhabits plains and acacia savanna ecosystems from southeastern Africa to central Kenya. Finish Purchase About the Product. Nevertheless, some fall prey to large carnivores, especially the spotted hyena. Wildebeest migrations are closely followed by vultures, as wildebeest carcasses are an important source of food for these scavengers. Overland migration as a biological process requires large, connected landscapes, which are increasingly difficult to maintain, particularly over the long term, when human demands on the landscape compete. In some animals, the tympanic part of the temporal bone is highly deformed, and in others, the radius and ulna are fused. In males, blue wildebeest stand 150 cm tall at the shoulder and weigh around 250 kg, while the black wildebeest stands 111 to 120 cm tall[29] and weighs about 180 kg. [14][24], The two species of the wildebeest are known to hybridise. The wildebeest is one of the few African antelopes to have extended its range. Description The Blue Wildebeest, also known as the Gnu, is an African bovid with broad shoulders, cow-like horns, and a broad muzzle. Some illegal hunting goes on but the population trend is fairly stable and some populations are in national parks or on private land. The wildebeest (/ˈwɪldɪbiːst/ WIL-dib-eest,[1][2][3] /ˈvɪl-/ VIL-,[3] /-dəb-/, plural wildebeest or wildebeests), also called the gnu (/njuː/ NEW or /nuː/ NOO),[4][5][6] is an antelope in the genus Connochaetes.
