Spider Monkeys' Secret Network Revealed: How They Share Insider Knowledge to Find the Best Food
In a fascinating discovery, researchers have uncovered the clever system used by spider monkeys to share information about food sources in their forest home. By constantly switching between subgroups of three or more individuals, these agile primates are able to complement each other's knowledge and combine it to create new insights.
The study, published in the journal njp Complexity, reveals that Geoffroy's spider monkeys - considered endangered and known as the Central American spider monkey or black-handed spider monkey - have developed a unique social behavior. They split into small subgroups and then rejoin in different combinations, allowing them to share information about the location of fruit trees and the timing of their ripening.
This "insider knowledge" sharing system enables the monkeys to enhance their collective knowledge, exploiting food sources according to their location and timing. The researchers used data from seven years of field observations in Mexico's YucatΓ‘n peninsula to analyze this behavior and found that the fluid social dynamics of spider monkeys have a significant impact on their foraging success.
According to Dr. Matthew Silk, an ecologist from the University of Edinburgh, "It isn't random social mingling. It's a clever system for sharing insider knowledge about where the best fruit trees are located across their forest home." The researchers tracked individual monkeys' movements and mapped out their core ranges, showing that some parts of the forest are known by multiple monkeys while others are known by only one or two.
By analyzing data from experienced observers between January 2012 and December 2017, the team found an optimal middle ground between the monkeys sticking together and spreading out too far. This allowed them to explore different areas but still reconnect often enough to pool their knowledge.
Professor Gabriel Ramos-Fernandez from the National Autonomous University of Mexico said that the group's collective intelligence is essential for their survival: "By exploring their environment in a distributed fashion and then coming together to share their uniquely obtained information, the group as a whole can know the forest better than a single individual could on its own."
