Male‐biased stone tool use by wild white‐faced capuchins ( Cebus capucinus imitator )

A male-biased pattern of stone tool use in white-faced capuchins (Cebus capucinus imitator) on Jicarón Island, Panama, contrasts with populations where both sexes use tools. Analysis of five years of camera trap data reveals that this bias is not due to physical limitations or competition over anvils, as adult females and juveniles demonstrate the ability to use tools. The study suggests that social structure, diet, and dispersal patterns may underlie such sex biases in socially learned behaviors, even when environmental constraints are absent.
