activity

Activity patterns. Allen’s Swamp Monkeys are diurnal and semi-arboreal-semi-terrestrial. Locomotion is quadrupedal, with climbing and leaping. They use the lowerstrata of the forest canopy and often forage on the ground. They can swim and will dive into a river to avoid predators, or flee on the ground rather than climb to safety. They sleep in trees 8 - 20 m above the ground along river edges and lake borders.

Habitat. Swamps in lowland moist forests, bordering lakes and rivers that are seasonally flooded. Allen’s Swamp Monkey is largely arboreal when the forest is flooded but more terrestrial when flooding recedes. It is also found in mangroves and occasionally enters terra firma forests and more open formations. It enters fields to raid crops.

Movements, Home range and Social organization. Home range sizes and the lengths of the daily movements of Allen’s Swamp Monkeys are unknown. They live in multimale-multifemale social groups of 23 - 57 individuals, but it is possible that the social organization is one of harems. Groups of 2 - 8 individuals tend to travel and forage together. Single males may travel separately during the day but join up with the group at night. They produce baboon-like grunts as they travel and also guenon-like, highpitched alarm chirps.
