The other is Grevy''s hiking 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.

The stripes on Grevy''s zebras are more numerous and narrow than those of the plains zebra and do not extend to the belly. In all zebra species, the stripes on the forequarters trail form a triangular pattern; Grevy''s have a similar pattern on the hindquarters, while others have a slanted or horizontal pattern. Burchell''s hiking zebras inhabit savannas, from treeless grasslands to open trail woodlands; they sometimes occur in tens of thousands in migratory herds on the Serengeti plains. Grevy''s zebras are now mainly restricted to parts of northern Kenya. Although they are adapted to semi-arid conditions and require less water than other zebra species, these zebras compete with domestic livestock for water and have suffered heavy poaching for their meat and skins. Family groups are stable members maintaining strong bonds hiking over many years. Mutual grooming, where zebras stand together and nibble the hair on each other''s neck and back, helps develop and preserve these bonds.

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 trail their necks entwine.
