Second nature : environmental enrichment for captive animals
An animal-as-client (AAC) theory for zoo exhibit design
The design of zoo exhibits has traditionally focused on the needs of humans. More recently, the needs of animals displayed in zoo exhibits have become a focus. However, there is no theory that describes how designers might consider animal needs, and how these needs might be interpreted in the design process. An animal-as-client (AAC) theory […]
The Evolutionary Origins and Ecological Context of Tool Use in New Caledonian Crows
New Caledonian (NC) crows Corvus moneduloides are the most prolific avian tool users. In the wild, they use at least three distinct tool types to extract invertebrate prey from deadwood and vegetation, with some of their tools requiring complex manufacture, modification and/or deployment. Experiments with captive-bred, hand-raised NC crows have demonstrated that the species has […]
