When do monkeys sleep?

Most monkeys are diurnal, meaning they are active during the day and sleep at night. However, there are a few exceptions, such as the nocturnal owl monkey. Monkeys typically sleep in trees, where they are safe from predators. They usually build a nest out of leaves and branches, and they may also use their tails to help them stay warm. Monkeys typically sleep for around 8-10 hours per day.
