About the Squirrel Monkey of Costa Rica
Habitat
Squirrel Monkeys make their homes in tropical evergreen forests, mangroves, and secondary forests.
Range
The squirrel monkey is found only in Panama and the Pacific lowlands and southern part of Costa Rica.
National Parks
Corcovado National Park, Manuel Antonio National Park
Physical Description
The squirrel monkey is mostly a greenish yellow color, with a white throat, face, and ears and a black muzzle and tail tip. The undersides of its limbs are white or yellow, and it has a long prehensile tail.
Biology and Natural History
Squirrel monkeys keep in groups which vary widely in size depending on the carrying capacity of their habitat: some troops are as small as 7 to 8, and others as large as 100 (these have been sighted in the Amazon basin). Several adult males will join in a single troop, and there are usually four adult females for every male. Females will have a single baby at a time after a 165-day gestation period.
This diurnal monkey has the most restricted range of Costa Rican primates, although it is very similar to and may be same species as Saimiri sciureus, another squirrel monkey which lives in Amazonian portions of Brazil, Colombia, Ecuador, Peru, Bolivia, Venezuela, and Guyanas.
Diet
Squirrel monkeys feed on insects, fruits, and sometimes leaves.
Height/Weight
An adult female head and body length averages 28 cm, males 30 cm; the tail is longer than the body, generally 35 to 43 cm. Adult females weigh 0.5 to 0.75 kg, and males weigh 0.7 to 1.1 kg.
