RESUMEN
This study examined captive cotton-top tamarin (Saguinus oedipus) behavior across 3 different exhibits: (a) a rainforest (30.5 m in diameter), where tamarins free-ranged with other species; (b) a caged outdoor exhibit (5 m in diameter); and (c) a caged enclosure, with access indoors (6 x 9m) and outdoors (2.5 x 2.5 m). The study observed tamarins using focal animal scan sampling in 10 min blocks. Scoring was on the percentage of intervals in which they engaged in 12 behaviors. The findings show significant differences in activity, inactivity, and visibility across exhibits and have important implications for reintroduction efforts.

Nonhuman animals in captivity manifest behaviors and physiological conditions that are not common in the wild. Lions in captivity face problems of obesity, inactivity, and stereotypy. To mediate common problems of captive lions, this study implemented a gorge and fast feeding schedule that better models naturalistic patterns: African lions (Panthera leo) gradually adapted from a conventional feeding program to a random gorge and fast feeding schedule. Digestibility increased significantly and food intake and metabolizable energy intake correspondingly decreased. Lions also showed an increase in appetitive active behaviors, no increase in agonistic behavior, and paced half as frequently on fast days as on feeding days. Thus, switching captive lions to a gorge and fast feeding schedule resulted in improved nutritional status and increased activity.
