A group of teenagers, a lot of free time, and little oversight from their elders. Great things can emerge from this scenario, but it’s also the ingredients for a series of tragic events in paradise. On Jicarón Island (Panama), within Coiba National Park, a dozen babies were torn from their mothers’ hands, dying days later amid the neglect and curiosity of their captors. The behavior observed among a group of white-faced capuchins (Cebus capucinus imitator) is extraordinary: the kidnapped monkeys were babies of another species, Panamanian howler monkeys (Alouatta palliata coibensis). It would seem like teenaged mischief if it weren’t for the fact that all the kidnapped monkeys died within a few days. The authors of this discovery can only find one explanation for a behavior with no obvious benefits or biological meaning: something very similar to boredom.
