Antelopes can be found, including Grant’s gazelles, impalas, duikers and Coke’s hartebeests. The plains are also home to the distinctive Masai giraffe. The large roan antelope and the nocturnal bat-eared fox, rarely present elsewhere in Kenya, can be seen within the reserve borders.

More than 470 species of birds have been identified in the park, many of which are migrants, with almost 60 species being raptors. Birds that call this area home for at least part of the year include: vultures, marabou storks, secretary birds, hornbills, crowned cranes, ostriches, long-crested eagles, African pygmy-falcons and the lilac-breasted roller, which is the national bird of Kenya.
