Environmental Enrichment

Includes structural, behavioral, food, and auditory enrichment.

Fangmeier, M. L., Burns, A. L., Melfi, V. A. et al. 2020. Foraging enrichment alleviates oral repetitive behaviors in captive red-tailed black cockatoos (Calyptorhynchus banksii). Zoo Biology 39(1), 3-12.

The relationship between inadequate foraging opportunities and the expression of oral repetitive behaviors has been well documented in many production animal species. However, this relationship has been less-well examined in zoo-housed animals, particularly avian species...

Glaspell, S. 2020. Flight to freedom: Behavior modification of an undomesticated pigeon using human interaction. Laboratory Animal Science Professional 8(2) (March/April), 58-61.

The white-crowned pigeon, Patagioenas leucocephala, is a species of bird not often used in research. This may be related to its anxiety during normal human interactions, such as with cage changing. Our institution acquired a...

Coleman, K., Weed, J. L., Schapiro, S. J. 2017. Chapter 2 - Psychological environmental enrichment of animals in research. In: Animal Models for the Study of Human Disease, Second Edition. Conn, P. M, (ed), 47-69. Academic Press, London, UK.

Environmental enrichment is an integral part of animal care practices. Enrichment generally refers to items we provide to the animals to support their behavioral needs. It provides a way to functionally simulate the natural environment...

Burghardt, G. M., Ward, B., Rosscoe, R. 1996. Problem of reptile play: Environmental enrichment and play behavior in a captive Nile soft‐shelled turtle, Trionyx triunguis. Zoo Biology 15(3), 223-238.

Giving captive animals the opportunity to interact with objects in a “playful” manner is often considered a method of environmental enrichment. However, the occurrence of play in nonavian reptiles is controversial and poorly documented. Similarly...

Jung, L., Knierim, U. 2019. Differences between feather pecking and non-feather pecking laying hen flocks regarding their compliance with recommendations for the prevention of feather pecking – A matched concurrent case-control design.

Feather pecking (FP) is a multifactorial problem in all housing systems. Using a case-control design we wanted to determine a set of variables which may be decisive for a flock to become case or control...

Dupont, M. 2017. An investigation into whether food-based environmental enrichment will increase the activity levels of Alaotran gentle lemurs (Hapalemur alaotrensis) at Birmingham Wildlife Conservation P

Excessive weight gain and obesity is becoming a more frequent problem affecting captive lemurs. Animals have evolved to survive in specific environments, causing them to perform species-specific behaviours which animals are highly motivated to perform...

Slaney, H. 2017. Using domestic animals as tiger enrichment. RATEL (Journal of the Association of British and Irish Wild Animal Keepers) 44(2), 24-27.

At Colchester Zoo we have a well established but evolving enrichment program, using many different ideas and techniques for our many different species. One form of enrichment we use is the presence of our domestic...

Fernandez, E. J., Kinley, R. C., Timberlake, W. 2019. Training penguins to interact with enrichment devices for lasting effects. Zoo Biology 38(6), 481-489.

The modern zoo has brought about two major advances in the behavioral welfare of their exhibited animals: (a) The use of environmental enrichment to promote naturalistic behaviors and (b) the use of training to improve...

Scott, N. L., LaDue, C. A. 2019. The behavioral effects of exhibit size versus complexity in African elephants: A potential solution for smaller spaces. Zoo Biology 38(5), 448-457.

Population-level analyses suggest that habitat complexity, but not necessarily space availability, has important welfare outcomes for elephants in human care. At the Dallas Zoo, the opening of a new exhibit complex allowed us to measure...
