Capuchin Monkeys on Jicarón Island Engage in Disturbing Kidnapping Behavior of Howler Monkey Infants
Recent findings reveal white-faced capuchins abduct howler monkey infants, with alarming implications for the endangered species' survival.
Caught on camera, capuchin monkeys kidnap howler monkey babies

Overview
Recent research highlights a troubling phenomenon among white-faced capuchins on Jicarón Island, Panama, where these monkeys have been observed abducting howler monkey infants. This behavior, which began in 2022 with a capuchin nicknamed Joker, has seen at least 11 howler infants kidnapped between January 2022 and March 2023. No evidence suggests that these capuchins harm the infants, but the babies inevitably succumb to starvation, raising concerns for the endangered howler population. Researchers propose boredom among juvenile capuchins may drive this unique behavior, a possible cultural fad without direct biological benefit.

Analysis
- The monkey abduction phenomenon observed among capuchins on Jicarón Island raises questions about animal behavior and adaptation, highlighting the potential for cultural evolution in non-human species.
- Researchers found ambiguous motivations behind the capuchin monkeys' actions, which may stem from boredom or curiosity rather than aggression or predation, showcasing the complexities of animal social behavior.
- The situation poses ethical dilemmas for scientists who must balance their observational studies with the pressing need to protect the endangered howler monkey population from further trends of baby abduction.

Researchers suspect the kidnapping behavior stems from boredom among young male capuchin monkeys, who mimic the actions of an individual monkey known as Joker.
The kidnapped infant howler monkeys were unable to survive without maternal care, leading to the death of at least four infants since 2022, raising concern for the endangered howler monkey population.
This behavior was first observed on Jicarón Island in Panama in early 2022, with camera traps capturing footage of capuchin monkeys carrying infant howler monkeys.
Capuchins and howler monkeys mostly cohabit without issue on Jicarón Island due to different diets and lack of food competition, but the recent kidnapping behavior is a new and unusual interaction between the species.
Researchers used motion-triggered camera traps placed around Jicarón Island to capture footage of the capuchin monkeys' unusual behavior, initially installed to study tool use but which revealed the kidnapping incidents starting in early 2022.
