The Long-Tailed Macaque is native to Southeast Asia and lives in a wide variety of habitats, including primary lowland rainforest, disturbed or secondary rainforest, shrub land, and riverine and coastal forests. Males are considerably larger than females and have a cheek pouch which they use to store food while foraging. Their tails are longer than the body which they use for balance when they jump distances of up to 5m. Fruits and seeds make up most of their diet but they also eat leaves, flowers, roots, bark and sometimes prey on vertebrates (including baby birds, nesting female birds, lizards, frogs, and fish), invertebrates, and bird eggs.
