The behavioral profile and environmental enrichment of a squirrel monkey colony

Five options were tested in alternation: crushed monkey chow in wood shavings, plastic ball, empty plastic bottle, PVC tube with finger holes and loaded with litter-nut-dried fruit mix, plastic jug with litter-nut-dried fruit mix. The two food dispensing objects were...
