In a Peru time study, what percentage of feeding time was dedicated specifically to insects by one capuchin group?

39%

Analyzing the time allocation during foraging provides insight into the relative energy investment required to obtain different food types, even when a food source is generally favored or plentiful. A detailed time study conducted on a capuchin group in Peru revealed a clear prioritization of effort based on nutritional return. This study demonstrated that the group dedicated a substantial portion of their feeding time, specifically 39 percent, solely to the pursuit and capture of insects. In comparison, generalized feeding on plant material accounted for only 22 percent of that observed time. This disparity suggests that acquiring high-value, mobile protein sources like insects demands a greater commitment of active foraging time compared to consuming more sedentary or readily available plant matter.
