Observe a brindled gnu herd migrating and grazing followed by zebras, crowned cranes, lions, and hyenas

A herd of wildebeests (Connochaetes taurinus) on the African savanna. Grazing along the way, the herd migrates in search of short grasses and other forage. Because wildebeests can swim, streams and rivers do not stop movement of the herd. Zebras often accompany the wildebeests, and crowned cranes lands among them. Predators, including lions and spotted hyenas, also travel with the herd. A large majority of the calves are born within a period of less than a month. The young are able to run less than 10 minutes after birth. This is vital, as the calves' survival depends on moving with the herd.
