Reproduction stages in squirrel monkeys
Adult male squirrel monkeys, aged three years, mate with one female, who becomes the mother of their offspring.
The male squirrel monkey builds a separate nest with her and shares in caring for the young.
Some monkeys mate covertly with more than one female, without emitting loud sounds to attract females, fearing exposure or being attacked and expelled from the group.
The paired individual is not well-liked among members of their tribe.
Squirrel monkeys only mate during the dry season over a period of two months.
Pregnant females within a group typically give birth within a week of each other..
The female gives birth after a gestation period of 6 months.
The infant monkey rides on the mother’s back in the first few weeks of its life and remains dependent on the mother for about a year.
This means that young monkeys can be weaned at the beginning of the rainy season when most food is available.
The juvenile monkey clings to its mother’s forehead in the first two weeks of its life and then starts clinging to her back
