Environmental enrichment is an important component in maintaining the welfare of animals housed in human care. While a variety of enrichment types (e.g., objects, food, sound) have been utilized, a major challenge in developing enrichment is determining the enrichment potential of various techniques for individual animals.

Videos were evenly divided into five categories, based on content, and played at underwater viewing windows across 20 sessions while the animals were housed with conspecifics. Species and …

Findings showed that the mother increased her rates both pre- and post-delivery, while other group members produced their whistles at decreased rates until the calf’s second week of life. After the calf’s second week, whistle rates of …
