Mammals at Grumeti:
Unlike other parts of the Serengeti, the western corridor has resident populations of large herbivores (elsewhere in the ecosystem, the vast majority of herbivores migrate). High densities of lion and spotted hyena hold territories around Grumeti River Camp. Resident herbivores are joined each season by huge numbers of migratory wildebeest and zebra. Bat-eared fox and serval are among regularly seen smaller carnivores. Family groups of black-and-white Colobus monkeys reside in the riverine forest. Pairs of dainty Kirks dik-dik inhabit bush-clump thickets. Handsome yellow-winged bats often roost in and around the camp.

Birds at Grumeti:
There are 341 species recorded at Grumeti. Black crake and African jacana dance across water-weeds in front of the camp. Large flocks of gregarious yellow-throated sandgrouse visit waterholes to quench their thirst. Striking black-headed gonolek, slate-coloured boubou and rufous chatterer forage close to camp. Dazzling Fischers lovebirds feed alongside grey-capped social weavers and blue-capped cordonbleu in bush clump thickets. Eastern grey plantain-eater, Schalows turaco and double-toothed barbet feed on fruiting trees in the riverine forest. Tawny eagle, bateleur and white-headed vultures are among breeding raptors.

Other Wildlife:
Massive Nile crocodiles inhabit the waters of the Grumeti River. Colonies of pugnacious cocktail ants live in whistling thorn trees. Several species of iridescent dragonflies hunt on the Kanyanja Pool opposite the camp.
