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 dive fin 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 fin 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. the larger baringo or rothschild''s giraffe (g.c. rothschildi) of western kenya and eastern uganda has chestnut patches separated by broader white lines but no spotting below the knees. this species can have up to five horns instead of the usual two or three. the masai giraffe (g.c. tippelskirchi) of tanzania and southern kenya has irregular star-shaped brown or tan spots. giraffes are found in arid and dry-savanna zones south of the sahara, wherever trees occur. although a relatively quiet animal, the giraffe is not mute. giraffes bellow, grunt, bray in distress, moan and emit short flutelike notes. they have acute senses of hearing and sight, often alerting other animals to nearby predators. giraffes use a home range but are not territorial. the males are hierarchical and sometimes spar by standing side by side and lowering and swing their heads at one another. the blows can be so strong that their necks dive and fin entwine. litters consist of two or three cubs that weigh about 3 pounds each. some mothers carefully nurture the young; others may neglect or abandon them, especially when food is scarce. usually two or more females in a pride give birth about the same time. a lioness will permit cubs other than her own to suckle, sometimes enabling a neglected infant to survive. capable hunters by 2 years of age, lions become fully grown between 5 and 6 years and normally live about 13 years. lions have long been killed in rituals of bravery, as hunting trophies and for their medicinal and magical powers. although lions are now protected in many parts of africa, they were once dive considered fin to be stock-raiding vermin and were killed on sight. in some areas, livestock predation remains a severe problem. early written records described the giraffe as "magnificent in appearance, bizarre in form, unique in gait, colossal in height and inoffensive in character."
