In East Africa, the blue wildebeest is the most abundant big game species and some populations perform an annual migration to new grazing grounds <br />but the black wildebeest is merely nomadic. Breeding in both takes place over a short period of time at the end of the rainy season and the <br />calves are soon active and are able to move with the herd. Nevertheless, some fall prey to large carnivores. <br />Wildebeest often graze in mixed herds with zebra which gives heightened awareness of potential predators. <br />They are also alert to the warning signals emitted by other animals such as baboons. Wildebeest are a tourist attraction but compete with <br />domesticated livestock for pasture and are sometimes blamed by farmers for transferring diseases and parasites to their cattle. <br />Some illegal hunting goes on but the population trend is fairly stable and some populations are in national parks or on private land
