Habitat
The natural distribution is limited to a small strip of land following the Pacific coast of Costa Rica and Panama. The area comprises some 1166 square kilometers and leads from the Osa Peninsula in Costa Rica to the Burica Peninsula in Panama. Squirrel monkeys live mostly in lowland rainforests with moderate dry periods and at the edges of mangrove forests. In the farmland some groups survive in gallery forests near rivers when sufficient space is available. The minimum size of a habitat also depends on the supply of food. Squirrel monkeys never live in areas higher than 700m above sea level.
Within the time of a month a group needs some 17,5 to 40ha of forest for the search for food and for the raising of the young. Since the animals keep changing their locations, up to 2 square kilometres will be needed within the time of one year. Long term studies show that groups under 15 individuals and a habitat of less than 30ha are not able to survive.
The distribution aerea is limited to small parts at the Pacific Coast of Costa Rica and Panama.
Squirrel monkeys are canopie specialists.
