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, golf 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 vacation 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.

The giraffe''s high shoulders and sloping back give the impression that its front legs are much longer than the hind legs, but they are in fact only slightly longer. The giraffe (as well as its short-necked relative the okapi from Central African forests) has a distinctive walking gait, moving both legs on one side forward at the same time. At a gallop, however, the gait changes, and the giraffe simultaneously swings the hind legs ahead of and outside the front legs, reaching speeds of 35 miles an hour. Its heavy head moves forward with package each powerful stride, and then swings back to stay balanced. Giraffes have "horns" not true horns but knobs covered with skin and hair above the eyes to protect the head from blows. The reticulated giraffe (Giraffa camelopardalis reticulata) golf of northeastern Kenya has large, chestnut-colored square patches defined by a network of fine white vacation lines.

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 package at one another. The blows can be so strong that their necks entwine.
