Squirrel Monkeys

Squirrel monkeys live in the tropical forests of Central and South America in the canopy layer. Unlike other New World monkeys, their tail is not used for climbing but as a kind of "balancing pole" and tool. Their movements in the branches can be very rapid.
They live in multi-male/multi-female groups with up to 500 members. These large groups can, however, occasionally break into smaller troops. They have a number of vocal calls, including warning sounds to protect themselves from large falcons, which are their natural predators. Their small body size also makes them susceptible to predators such as snakes and felids. For marking territory, squirrel monkeys rub their tail and skin with their own urine.
Squirrel monkeys are omnivores, primarily eating fruits and insects. They occasionally consume seeds, leaves, flowers, buds, nuts, eggs, and small vertebrates.
