This elegant, brown antelope is easily recognized by its long neck and legs and white underparts. Gerenuks are browsers and are often seen standing up on their hind legs, with long necks outstretched, feeding on tender leaves and shoots of a bush. Gerenuks typically live in dry country and seldom drink, getting most of the water they require from food. They live either in small family parties of one adult male with several females and young, or in pairs. The males have heavily ridged horns which curve backwards.
Females have no horns and a dark patch on the crown.
The ostrich is the world's largest bird and the only flightless bird native to Africa. Males are conspicuously black and white with naked necks and thighs which turn bright pink during courtship. The breeding season extends from around August to December. Single males defend large territories, court females who enter, singly or in small groups, and guide them to a nesting hollow, where several different hens may lay up to 30 eggs, at the rate of one every other day. This is too many eggs for one ostrich to cover and the extras are left around the nest and fail to develop.
