Mangabeys can be very noisy! A special throat sac gives them a booming voice.

Like many monkey species, mangabeys lick nectar from flowers, moving from tree to tree for this sweet feast, earning them status as pollinators as well as seed dispersers. Mangabeys are mainly fruit eaters, although they can also eat leaves, nuts, seeds, insects, and spiders.
