De Brazza's Monkey Scientific Name: Cercopithecus neglectus Range: Central and Eastern Africa Habitat: Rainforests; swamp, bamboo and dry mountain forests Natural Diet: Seeds and fruits Zoo Diet: Commercial primate biscuit and vegetables Physical  Characteristics: De Brazza’s monkeys are covered with brown fur with a whitish upper-lip and white chin fur.  They also have a thin, white thigh stripe and a ginger colored brow.  Their length is 20-23 inches, their height is 23-31 inches, and they weigh 15-18 pounds. Behavior: De Brazza’s monkeys live in troops of normally one male, one or more females and their young.  Sometimes they will live in a smaller group of one male and one female. They mark their territory with saliva and scent, but they would rather avoid than challenge an intruder.  If another monkey species approaches their territory, the whole troop may force the intruders from their territory.  They use deep, booming calls to communicate. Reproduction: De Brazza’s monkeys breed throughout the year.  Their gestation period is about 168-187 days.  Usually a single infant is born; twins are rare.  Infants are covered with light brown hair.  They cling to their mother’s stomach for security and protection from predators such as leopards, eagles, pythons and other primates. Notes:   When they are looking for food in open areas, they store food in their cheek pouches.  Later, when they are in a safe area, they will eat their food.
