Topi are a grazing antelope with a mahogany and black coat that live in large migratory herds on African grasslands. Both sexes sport the almost two feet long heavily ringed lyre-shaped horns. They join up with other herbivores such as wildebeests, zebras and gazelles and are referred to as the savannah security, spending hours standing on a termite mound and announcing the dangers of approaching predators such as big cats and hyenas to all.

During the mating season, male topi gather to form 'leks' which are small patches of ground that they attempt to defend from rivals and display their fitness to potential mates. Receptive females leave their herd and travel to the lekking site, choosing several males to mate with over a couple of days.
