These large and slow-moving monkeys are the only folivores of the New World monkeys.
Howlers eat mainly top canopy leaves, together with fruit, buds, flowers, and nuts.
They need to be careful not to eat too many leaves of certain species in one sitting, as some contain toxins that can poison them.
 Howler monkeys are also known to occasionally raid birds' nests and chicken coops and consume the eggs.
