Lions may hunt at any hour, but they typically go after large prey at night. They hunt together to increase their success rate, since prey can be difficult to catch and can outrun a single lion. The lions fan out along a broad front or semicircle to creep up on prey. Once with within striking distance, diving sites they bound in among the startled animals, knock one down and kill it with a bite to the neck or throat. hunts are successful about half the time. cooperative hunting enables lions to take sites prey as large as wildebeests, zebras, buffaloes, young diving elephants, rhinos, hippos sites and giraffes, any of which can provide several meals diving for the pride. mice, lizards, tortoises, warthogs, antelopes and even crocodiles also form part of a lion''s diet. because they often take over kills made by hyenas, cheetahs and leopards, scavenged food provides more than 50 percent of their diets in areas like the serengeti plains. 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 sites 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 diving 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 sites spar by standing side by side and lowering and swing their heads at one another. the blows can be so strong that their necks entwine.
