A 503-contact-hr study of a 35 member group ofCebus albifrons was conducted in eastern Colombia in 1977 and 1978. The reactions of the group often centered on the largest adult male, which seemed dominant over all other members of the group. This “alpha” male reacted to perceived danger by putting himself between the group and the danger where he threatened and observed until the other members left the scene. Many members of the group sought the alpha's physical support while using threatening behaviors. Much tolerance towards juveniles and infants was shown by adult and subadult males which included carrying young animals out of danger. Territorial behavior was observed towards neighboring groups. Many behaviors were similar to other species ofCebus.
