The wildlife of Aberdare is very impressive though the vegetation cover which is thick, makes it hard to view animals apart from when you are in the lodges.

The rich forest sustains numbers of elephants, buffalo, warthog and many species of antelope for example; waterbuck, duiker, suni, dik-dik, eland, bushbuck and reedbuck. The park supports a healthy number of black rhino and also provides a chance to view some of the typical forest species like the giant forest hog or the shy and beautiful tongo, probably the most scarce and very impressive amongst Kenya Safari antelopes.

Animals that belong to the group of mammals are represented by black and white colours, sykes’ monkeys and vervet monkeys. Regarding the felines, lions show their adaptation to mountain, behaviour of tree-climbing and a longer and speckled coat.
Lions have increased in number in a way that a programme for killing a number of them has been carried out to protect some of the animals that eat plants, specifically the rare bongo. Leopards and servals are also there, sometimes I their melanic type, showing a black coat that is always associated with an adaptation to the high area above sea level.

Over 200 species of birds have been found in the park.
The tourist Kenya Tours can view the crowned eagle among them, which feeds on monkeys, or listen to the noisy silvery-checked hornbill. Sunbirds are represented by the violet Tacazze, the malachite of the scarlet tupted malachite in the high moorlands. Some groups of doves and pigeons are usual inhabitants of the upper forest layers. Water holes always host black-headed herons, Egyptian geese, sacred ibis and yellow-billed ducks, to mention but a few.
