The black wildebeest, or white-tailed gnu, is native to southern Africa, especially open grassland regions of South Africa, Lesotho, and surrounding areas. Males usually weigh about 240–345 pounds, with females slightly smaller; males stand roughly 44–48 inches at the shoulder. They are dark brown to black, have a pale or whitish upright mane, a long white tail, and forward-curving horns in both sexes. Black wildebeest are strong grazers, social herd animals, and known for territorial bulls. They were introduced into U.S. zoological and exotic-ranch collections primarily during the mid-to-late 20th century, as African plains game became common in safari parks and private ranch breeding programs.
