Bald-headed uakari  (Cacajao calvus)

Bald-headed uakaris are found in large multimale-multifemale groups, which may number up to 100 individuals although these larger troops are themselves composed of smaller, mixed groups (5). Females give birth to a single offspring between December and March; infants are initially carried on their mother's front before being transferred to her back to be transported through the treetops (5).

Fruit makes up the majority of the uakari diet, although they will also consume buds, leaves and insects (5). These monkeys are active during the day and spend most of their time in the trees, only alighting on the ground to search for food in the leaner times of the dry season (5).
