Some illegal hunting goes on but the population trend is fairly stable and some populations are in national parks or on private land.The International Union for Conservation of Nature lists both as least-concern species. Wildebeest is Dutch for "wild beast" or "wild cattle" in Afrikaans (bees "cattle"), while Connochaetes derives from the Greek words κόννος, kónnos, "beard", and χαίτη, khaítē, "flowing hair", "mane".
Males are larger than females and both have heavy forequarters compared to their hindquarters.
They have broad muzzles, Roman noses, shaggy manes and tails.
The differences in social behaviour and habitats have historically prevented interspecific hybridisation between the species, however hybridisation may occur when they are both confined within the same area. 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.
Another study reported an increase in the size of the hybrid as compared to either of its parents.
Due to their resemblance to wild cattle, these people called them "wild ox" or "wildebeest".
The blue wildebeest was first known to westerners in the northern part of South Africa a century later, in the 1800s.The wildebeests, also called gnus, are a genus of antelopes, scientific name Connochaetes.They belong to the family Bovidae, which includes antelopes, cattle, goats, sheep and other even-toed horned ungulates.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 and weighs about 180 kg.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.They are also alert to the warning signals emitted by other animals such as baboons.
