Black-Capped Squirrel Monkey Facts

Primarily, black-capped squirrel monkeys are arboreal and found in native and plantation forests and some managed areas close to running water.
Along with humans, Saimiri boliviensis is among the few primate species to display a wide variety of play behaviors.
They mostly dwell in female-dominated groups of about 40 to 75 monkeys. However, males have been observed splitting off after reaching sexual maturity to live in all-male groups.
Males establish dominance through vigorous fighting and assert dominance through forced submission of an inferior and urine-washing.
Saimiri boliviensis is among the most vocal of the squirrel monkeys. There are about 26 identifiable calls, comprising peeps and chirps (used in alarms), purrs and screeches (used during mating and birthing seasons), aggressive barks, and cries of pain.
