Titi monkeys are found in Brazil in the Amazon River basin, in forests and swamps along river and lake shores in the lower tree canopy. They are arboreal and rarely come to the forest floor. Titis move through the understory of the forest quadrupedally, as well as by leaping. However, when feeding they sit vertically on branches and trunks. Titi monkeys generally stay in low canopy forest, near rivers. They may rest quietly in dense vegetation for long periods.
