The Patas Monkey (Erythrocebus patas) grows to 85 cm in length, excluding the tail, which measures 75 cm. The Patas monkey has a russet-red coat, gray chin whiskers and white military mustache and walk on their fingers, not on their palms. It has long legs, narrow body and prominent rib cage and is probably the fastest primate on earth; its long legs give it a tremendous loping stride. Adult males are considerably larger than adult females. The Patas Monkey lives in multi-female groups of up to 60 individuals, and avoids dense woodlands living in more open savanna and semi-deserts. The patas can climb small trees when alarmed but usually rely on their speed on the ground to escape from danger.
The Patas Monkeys are omnivorous, but can apparently feed on either animal or vegetable food alone. They search on the ground for insects, grubs, buds, gum, seeds, leaves, fruits and tubers, and young birds and eggs, a diet more characteristic of small primates.
Patas monkeys can be found in Kidepo Valley National Park and Murchison Falls National Park in Uganda.
