Profile (Picture) The Central American squirrel monkey weighs up
to about 1 kg (2.2 lb). It is found in primary and secondary
forests and cultivated areas. Disturbed habitats are
advantageous because of their greater supply of preferred food -
insects (such as grasshoppers) and fruit. The Central American
squirrel monkey is arboreal and diurnal. It rarely travels on
the ground and is most active in the morning and late afternoon.

70 individuals) in continuous forest. They are non-aggressive
and egalitarian - neither males nor females appear to be
dominant. Females are usually the ones who disperse to another
troop. The Central American squirrel monkey has always been
restricted to the Pacific lowla
