Environmental enrichment for marmosets

Marmosets are among the easiest of primates to provide with environmental enrichment. Like other higher primates, they need companionship, adequate space with incorporated complexity, some unpredictability in the environment, ways in which they can manipulate or control their environment.

Gorilla husbandry/enrichment at the Dallas Zoo

Unintrusive husbandry techniques during cleaning and feeding, such as shifting animals, allow keepers to easily incorporate environmental enrichment components during their normal routine. To create a stimulating and diverse environment, keepers supply simple, economic [unspecified] items which allow the gorillas...
