Traditional studies of primate sociality have focused on the
roles of competition and aggression in structuring within-group social
interactions. However, group living requires that individuals form predictable
social relationships, exploit a common set of resources, and defend a common
range, which is facilitated by the development of mutually beneficial social
bonds. In this chapter examine the set
of factors that serve to promote cooperation and affiliation in male
pitheciines. In taxa such as Chiropotes,
Cacajao, and some species of Pithecia, stable groups may contain as
many as 4 to 16 fully adult males. Data
on social interactions indicate that contest competition at feeding sites is
low, and patterns of spatial affiliation and grooming among resident males
indicates a high level of intrasexual tolerance. We argue that in species characterized by a
nondespotic social system in which all or most males obtain, at least some
access to receptive females there are benefits to all male group members of
collectively excluding extragroup males from obtaining access to fertile
females. In this regard, cooperative behavior is one component of a males
reproductive strategy that can promote group stability, increase the number of
co-resident males, and possibly serve to attract a large number of adult female
group members.
