Cheetahs do not roar like lions, but they purr, hiss, whine and growl. They also make a variety of contact calls; the most common is a birdlike chirping sound. Once a cheetah has made a kill, it eats quickly and keeps an eye out for scavengers lions; leopards, hyenas, vultures and jackals will occasionally take away their kills. Although cheetahs usually prey on the smaller antelopes such as Thomson''s gazelles and impalas, they can catch wildebeests and zebras if hunting together. They also hunt hares and other small mammals and birds. Although known as an animal of the open plains that relies on speed to catch its prey, research has shown that the cheetah depends on cover to stalk prey. The cheetah gets as close to the prey as possible, then in a burst of speed tries to outrun its quarry. Once the cheetah closes in, it knocks the prey to the ground with its paw.

Ancient cultures in Africa revered the giraffe, as some modern cultures do today, and commonly depicted it in prehistoric rock and cave paintings. Unknown outside of Africa, this animal so excited man''s curiosity that it was sometimes sent as a diplomatic gift to other countries; one of the earliest records tells of a giraffe going from "Melinda" (presumably Malindi) in Kenya to China in 1415. The animal was thought to be a cross between a camel and a leopard, a mistake immortalized in the giraffe''s scientific name of Giraffa camelopardalis. The neck is so long the giraffe must spread its front legs apart so its head can reach the ground to drink. It has unusually elastic blood vessels with a series of valves that help offset the sudden buildup of blood (and to prevent fainting) when the head is raised, lowered or swung quickly. In some areas, livestock predation remains a severe problem.

The other is Grevy''s zebra, named for Jules Grevy, a president of France in the 1880s who received one from Abyssinia as a gift, and now found mostly in northern Kenya. (The third species, Equus zebra, is the mountain zebra, found in southern and southwestern Africa.) The long-legged Grevy''s zebra, the biggest of the wild equids, is taller and heavier than the Burchell''s, with a massive head and large ears. Zebras have shiny coats that dissipate over 70 percent of incoming heat, and some scientists believe the stripes help the animals withstand intense solar radiation. The black and white stripes are a form of camouflage called disruptive coloration that breaks up the outline of the body. Although the pattern is visible during daytime, at dawn or in the evening when their predators are most active, zebras look indistinct and may confuse some predators by distorting the true distance between them and their prey.
