Behavioral enrichment is the environmental enhancement of the lives of animals in a managed setting by providing them with mental and physical stimulation to increase natural and healthy behavior. In other words; adding a little creativity, fun and stimulation to our animals’ lives!

Behavioral enrichment should be random, interesting and novel. The goals of enrichment are to offer a sense of control by allowing animals to make choices and to stimulate species-appropriate behaviors while interpreting these behaviors to our guests.

The Phoenix Zoo is lucky to have an internationally respected expert in behavioral enrichment on staff. Hilda Tresz has traveled all over the world offering her expertise and knowledge to several zoos, reserves and other animal organizations.
