Okavango Delta, Botswana
2000
Chris Johns

"On the move across the Okavango Delta, Cape buffalo herds (here with an egret aerial escort) number as many as 2,000 animals. One of the hunter-prized 'big five'???lions, rhinos, leopards, and elephants are the others???Cape buffalo play a key role in the delta ecosystem. Feeding on tall, coarse grasses, they make smaller tender plants accessible to other grazers."
