Assessing Vigilance Behavior in Wild Bearded Capuchin Monkeys (Sapajus Libidinosus)
Dorothy. M. Fragaszy and Emily S. Garner
We used a fixed water source to study vigilance during drinking in wild bearded capuchin monkeys. We recorded individual monkeys (N = 27) drinking water from a bowl attached to a platform mounted in a tree. The monkeys had to lower their eyes below the rim of the bowl to drink. The set-up permitted clear operational definitions for looking away from the bowl, into the bowl, and drinking. The method can support experimental probing of vigilance across conditions and populations. We present normative descriptions of looking behavior by the monkeys in this situation. Our findings largely replicate those of another study of capuchin monkeys using a similar design.
