Enrichment for owl monkeys: A discussion (2004)

Abbuhl, L., Sorrells, A., Feurtado, M.

Abstract

We tried to provide different levels elevation, so the hammock hangs high in the cage and the nest box below it. They use their nest boxes often to hide in, as they are shy animals. But when they are just hanging out uninterrupted the day, they will use the hammocks. Be patient when ANYTHING new to these guys, as they require a long acclimation. They may not use something you provide them for a long while eventually warm up to it as their trust builds.
