Eland

Tragelaphus oryx


Description

The common eland (Taurotragus oryx), also known as the southern eland or eland antelope, is a savannah and plains antelope found in East and Southern Africa. It is a species of the family Bovidae and genus Taurotragus. It was first described by Peter Simon Pallas in 1766. An adult male is around 1.6 metres (5') tall at the shoulder (females are 20 centimetres (8") shorter) and can weigh up to 942 kg (2,077 lb) with an average of 500–600 kg (1,100–1,300 lb), 340–445 kg (750–981 lb) for females). It is the second largest antelope in the world, being slightly smaller on average than the giant eland.

Mainly a herbivore, its diet is primarily grasses and leaves. Common elands form herds of up to 500 animals, but are not territorial. The common eland prefers habitats with a wide variety of flowering plants such as savannah, woodlands, and open and montane grasslands; it avoids dense forests. It uses loud barks, visual and postural movements and the flehmen response to communicate and warn others of danger. The common eland is used by humans for leather, meat, and rich, nutritious milk, and has been domesticated in many areas.

It is native to Angola, Botswana, the Democratic Republic of the Congo, Ethiopia, Kenya, Lesotho, Malawi, Mozambique, Namibia, Rwanda, South Africa, South Sudan, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe but is no longer present in Burundi. While the common eland's population is decreasing, it is classified as "Least Concern" by the International Union for Conservation of Nature (IUCN).

Common elands are spiral-horned antelopes. They are sexually dimorphic, with females being smaller than the males.[10] Females weigh 300–600 kg (660–1,320 lb), measure 200–280 cm (79–110 in) from the snout to the base of the tail and stand 125–153 cm (49–60 in) at the shoulder. Bulls weigh 400–942 kg (882–2,077 lb), are 240–345 cm (94–136 in) from the snout to the base of the tail and stand 150–183 cm (59–72 in) at the shoulder. The tail is 50–90 cm (20–35 in) long.[3] Male elands can weigh up to 1,000 kg (2,200 lb).

Their coat differs geographically, with elands in north Africa having distinctive markings (torso stripes, markings on legs, dark garters and a spinal crest) that are absent in the south. Apart from a rough mane, the coat is smooth. Females have a tan coat, while the coats of males are darker, with a bluish-grey tinge. Bulls may also have a series of vertical white stripes on their sides (mainly in parts of the Karoo in South Africa). As males age, their coat becomes more grey. Males also have dense fur on their foreheads and a large dewlap on their throats.

Both sexes have horns with a steady spiral ridge (resembling that of the bushbuck). The horns are visible as small buds in newborns and grow rapidly during the first seven months. The horns of males are thicker and shorter than those of females (males' horns are 43–66 centimetres (17–26 in) long and females' are 51–69 centimetres (20–27 in) long), and have a tighter spiral. Males use their horns during rutting season to wrestle and butt heads with rivals, while females use their horns to protect their young from predators.

The common eland is the slowest antelope, with a peak speed of 40 kilometres (25 mi) per hour that tires them quickly. However, they can maintain a 22 kilometres (14 mi) per hour trot indefinitely. Elands are capable of jumping up to 2.5 metres (8 ft 2 in) from a standing start when startled (up to 3 metres (9.8 ft) for young elands).The common eland's life expectancy is generally between 15 and 20 years; in captivity some live up to 25 years.

Eland herds are accompanied by a loud clicking sound that has been subject to considerable speculation. It is believed that the weight of the animal causes the two halves of its hooves to splay apart, and the clicking is the result of the hoof snapping together when the animal raises its leg. The sound carries some distance from a herd, and may be a form of communication.


Fun Facts

Ecology And Behavior

Common elands are nomadic and crepuscular. They eat in the morning and evening, rest in shade when hot and remain in sunlight when cold. They are commonly found in herds of up to 500, with individual members remaining in the herd anywhere from several hours to several months. Juveniles and mothers tend to form larger herds, while males may separate into smaller groups or wander individually. During estrus, mainly in the rainy season, groups tend to form more regularly. In southern Africa common elands will often associate with herds of zebras, roan antelopes and oryxes.

Common elands communicate via gestures, vocalizations, scent cues and display behaviors. The flehmen response also occurs, primarily in males in response to contact with female urine or genitals. Females will urinate to indicate fertility during the appropriate phase of their estrous cycle, as well as to indicate their lack of fertility when harassed by males.If eland bulls find any of their predators nearby, they will bark and attempt to attract the attention of others by trotting back and forth until the entire herd is conscious of the danger.Some of their main predators include lions, African wild dogs, cheetahs and spotted hyenas. Juvenile elands are more vulnerable than adults to their predators.
