At night, kinkajous race around the trees in search of fruit. After searching through one tree, they will cautiously move to the next before beginning to forage again. They use their long tongues to reach the soft fleshes and juices inside the fruit.
Kinkajous tend to return to the same roosting trees each dawn. They travel alone or in breeding pairs. However, groups of kinkajous may form in trees that are heavy with fruit. Kinkajous leave their scent on branches, probably as a signal to potential mates. They also give shrill calls to communicate with partners. Mating takes place all year round, and single offspring are born after four months.
