Central American squirrel monkey
Central American squirrel monkeys (S. oerstedti), found in forests of Costa Rica and Panama, eat fruits and insects and are preyed on by raptors and snakes. They exhibit no hierarchy between males and females or among females, and very little hierarchy among males. They live in groups of 40 to 65 animals.[1] The males cooperate in sexually investigating females, aggression toward neighboring groups, and defending themselves from predators.[2]
The Central American squirrel monkey belongs to the Saimiri genus. South America's squirrel monkey species are far more hierarchical. The difference in social organization may have to do with how fruit is distributed. Central American squirrel monkeys forage large fruit patches, where they tend to find few fruits at a time and quickly move on to other patches. Peru's squirrel monkeys (S. boliviensis), however, tend to find large amounts of fruit at a time, and members of a group compete for the fruit. Common squirrel monkeys (S. sciureus) tend to find fruit concentrated in small patches, so members of a group will fiercely compete to control the small patch.[3]
The Central American squirrel monkey is threatened by deforestation, forest fragmentation, and hunting.[4]
