Wildebeest Wildebeest Wildebeests, also called gnus, are antelopes in the genus Connochaetes. They belong to the family Bovidae, which includes antelopes, cattle, goats, sheep, and other even-toed horned ungulates. "Connochaetes" includes two species, both native to Africa: the black wildebeest or white-tailed gnu ("C. gnou"), and the blue wildebeest or brindled gnu ("C. taurinus"). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black wildebeest changed more in order to adapt to
Wildebeest vultures, as wildebeest carcasses are an important source of food for these scavengers. The vultures consume about 70% of the wildebeest carcasses available. Decreases in the number of migrating wildebeest have also had a negative effect on the vultures. 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. Zebras and wildebeest group together in open savannah environments with high chances of predation. This grouping strategy reduces predation risk because larger groups decrease each individual’s chance of being hunted, and
