Space Use Preferences and Species Proximity in a Mixed-Species Zoo Monkey Exhibit
2025
Neil Chace | Susan W. Margulis
Many zoos display animals in mixed-species exhibits where multiple different species share the same space and potentially interact. This study analyzes a mixed-species exhibit with three New World monkey species (white-faced saki, black-capped squirrel monkey, and common squirrel monkey) at the Buffalo Zoo to determine the interactions among species and how different species use the exhibit space differently. Data were collected over twelve months using scan sampling. The sakis were more likely to be in proximity (less than 1.5 m apart) with others than were the squirrel monkey species. The sakis spent 26% of the time in contact with another animal, while both squirrel monkey species spent less than 1% of the time in contact with another animal. The squirrel monkeys used significantly more of the exhibit space than the sakis. A small number of observations occurred when only the sakis were on exhibit, and while speculative at best, anecdotally the sakis used much more of the exhibit when the squirrel monkeys were not on exhibit. There are many compelling reasons for zoos to design mixed-species exhibits: however, consideration needs to be given to how mixed-species exhibits impact animal behavior.
