When to see them?
Early morning and mid-afternoon when family troops are on the move through the canopy feeding. Keep your eyes on the canopy and look for tree limbs that shake suddenly. You will probably hear them before you see them.

What to do?
Keep voices low and walk quietly. Capuchin monkeys used to curious visitors may be quite bold. Although it’s tempting, refrain from feeding them since it could cause the monkeys serious health problems. Howlers are territorial as are spider monkeys. If they feel you are too close to their females and young, they will shake the trees and loudly pronounce their displeasure.
