Green monkeys live in troops - family groups that can number anywhere from a few individuals up to several dozen. They communicate with each other using different calls and facial expressions, almost like having their own language. Scientists who study them have identified many distinct calls that mean specific things, such as 'predator above' or 'food found'.
They are very clever animals. Green monkeys have been spotted raiding fruit trees, figuring out how to open containers, and even watching humans closely to learn new tricks. Their favourite foods include fruit, leaves, flowers, seeds, and insects.
Because green monkeys have been on Barbados for so many generations without many natural predators, they have become very comfortable around people. You are most likely to spot them at dawn or dusk, when they come down from the trees to forage. Welchman Hall Gully and the Barbados Wildlife Reserve are two of the best places to see them up close.
