Scientists captured the recordings of an unusual social tradition in Capuchin monkeys Deprivation of newborns of interest in monkeys – continuously seen behavior in wild recipients.
Researchers on the island of Jicarón from the banks of Panama they found a baby Howler Monkey Paste on the back of the older male monkey, his tiny fingers that catch her fur.
But they are not connected and Not even the same kind.
Scientists noticed surprising evidence of what they describe as monkey abductions while browsing videos.
Capuchin monkeys were seen to carry at least 11 Babdies for Howler between 2022. and 2023. years.
“This was a very shocking finding,” Zoolsborough said, a behavioral ecologist at Max Planck Institute for animal behavior in Germany. “We didn’t see something like that in the animal kingdom.”
Monkey motivation remain under investigation.
Capuchins are a household cat monkeys found South America and Central America. Long live, smart and learn new behaviors from each other. One group of Capuchin in Panama has even learned to use stone tools for cracking open nuts and seafood.
Goldsberg and other researchers in Max Planck and Smithsonian Tropical Research Institute have set more than 80 cameras to study the use of capacin tools, but were surprised when the first babe for Howler was seen in early 2022. Years.
The recordings showed cappuccins that walk and hit their stone tools with children’s cars on their backs. But the cameras did not catch the moments of kidnapping, which scientists said that he probably happened in the trees, where she hired most of her time.
“Our window in this story is limited,” said Koautor Margaret Crofoot from Max Plancan and Smithsonian. The findings were published on Monday in the journal Current Biology.
In most or all cases, Baby Howlers died, researchers said. Infant Howler monkeys would usually carry their mothers while still denying. All babies in the video – from a few weeks to a few months in age – were too young to refuse.
“Hopper part of me wants to believe that some escaped and returned to their mothers, but we don’t know,” Crofoot said.
Videos recorded several cases of young cappucine t-shirts that continue to wear Howler’s babies who died, probably from hunger.
Many animals – from Gorilla to Orcas – were observed wearing their dead offspring, although scientists are unsure of reasons.
Why did the cappuccino males do that? There were no signs of deliberate aggression against babies, and did not eat, judgment, deciding.
“We all spent our brain work forces why they would do it,” Goldsborough said.
The first baby-snakeer may have had a confused “caring motivation” or parent instinct, because he showed the tenderness that communicates with newborns, she said. Then four other males copied his actions.
The researchers said they did not believe that the cappuccines intentionally harmed baby. So far, only one group of cappucins is known.
The research shows “outstanding variations in behavior in the same species,” said Catherine Crockford, the primatologist at the CNRS Institute for Cognitive Sciences in France, which was not involved in the studio.
