Behaviour
Spider Monkeys are very social animals.
They are active during the day and sleep at night. Females outnumber males in these groups by 2 to 1 usually. Female spider monkeys are usually more dominant in spider monkey troops.
They often gather together in groups of 20 to 30, but they sleep and forage for food in smaller groups. They concentrate on foraging early in the morning. They can be very noisy animals and communicate with calls, screeches, barks, and other noises. When threatened, they will bark, screech or make noises to try and scare the danger off. If this doesn't work, they will separate and head off in different directions. In some extreme cases, they might twist off branches so that the branches might fall and hit the intruder. They like to stay in the upper canopy of rainforests. They rarely go on the forest ground execpt for the Geoffroy's Spider Monkey which goes on ground more often. Grooming happens during the day when they pick parasites off each other. Since spider monkeys do not have thumbs, their grooming is not developed and does not happen so often. So they scratch alot with hands and feet. Most of the grooming done is between baby spider monkeys and their mothers.
