Capuchin monkeys on a remote development island kidnap children from the families of Howler Monkey, in a direction of its kind.
Brootan population of white face (white face)Cibos BingsenosLiving on Jicarón Island has been monitored with 86 movement cameras since 2017 to capture its advanced use of stone tools to break solid fruits, nuts and shellfish. Five years after the shots were recorded, in 2022, one of the researchers noticed one of the young cablemchane monkeys with an infant monkey of another kind clinging to his back. This cable, nicknamed Joker, picked up at least four children’s monkeys (Pendant Palliaata Coibensis) For four months, sometimes hold them for more than a week.
Initially, the researchers believed that it was the case of “one individual might be a little strange or a little strange.” Zoe Goldsburo From the Max Planck Institute for animal behavior, which discovered behavior. “We did not expect to find this.”
After that, five months after a Joker seen a baby, four other young men with two young children were found. For 15 months, the Capuchin group took 11 children under the age of four weeks.
The behavior about the population through social learning, such as “heresy or major costumes, says,” He says, he says, he says Andrew Whiteon At St. Andrews University, the United Kingdom, which has not participated in the study.

While mature female monkeys sometimes adopt abandoned children from other types, which may be a way to care for their young, Jicaròn monkeys that do so are all immature males. Instead of adopting the displaced infants, they appear to be actively taking from their families. There are no theft footage, but they documented the cabins that prevent the children from escaping. The footage also shows that the parents in the Howler Monkey are searching and calling for their children in the umbrella where the capsuin gets the defense.
Children who were all kidnapped may die due to malnutrition, because they are very young to stay without their mother’s milk. The researchers saw at least three children a monkey monkey being transported even when they died.

Learning from others can be useful, which is why the trend can be launched even when behavior does not have real benefits for monkeys, says Whiteon.
Since Jicarón Capuchins do not have predators and a very few competition, madness arose as a result of a vacuum to experience new things, and perhaps out of boredom. There may also be something about the conditions of life on a remote island that leads to innovative emerging behaviors and spread. These male monkeys themselves are the ones who use most tools on jicarón, note GoldsBorough. “Maybe if you already have a tradition, you are more likely to copy their other behaviors.”
