Captive nonhuman animals use enclosure space differentially. Enclosure features strongly influence this. This study recorded both the enclosure space used by 47 captive lion-tailed macaques housed in 13 zoos across India and the behavior of the macaques. The exhibition of abnormal behaviors, food-related behaviors, and social interactions correlated significantly with the use of the edge zone (the part of the enclosure closest to the visitor area). Animals housed in barren enclosures used the edge zone to a significantly greater percentage than did those housed in complex exhibits. Percentages of autogrooming, social interactions, and food-related behaviors significantly correlated with the use of the enrich zone. Space use studies assist in recognizing areas within the enclosure, which captive animals actively use. Conversely, the studies can identify areas infrequently used and show how to make maximum use of these enclosure areas. Further studies targeting both the increase in percentages of natural behaviors exhibited and use of the enrich zone used the current study on captive lion-tailed macaques for their design.
