Black Howler Monkey
Where do they live?
- Black Howler monkeys are New World monkeys that live in the rainforests of Central and South America. They mostly live in the tops of the trees where there are good leaves to eat. At night they sleep in nests that they make high in the tree tops, away from predators on the ground.

What do they eat?
- Their diet consists mostly of leaves. They also eat flowers and fruit when they can find them. Leaves are not very nutrition, so it is important that they get younger prime leaves which provide the most nutrition for energy. Leaves are hard to digest. Their bodies have adapted so that they are able to process the leaves and get the required nutrients. They have a special sac at the beginning of their intestines so that they can eat lots and lots of leaves and not get sick.

Why are they called Howler monkeys?
Howler monkeys have a very distinct call when they are marking their territory or communicating with others. Their howls are not piercing, but more of a very loud rasping sound. Their calls can be heard up to 2-3 miles away in dense rainforests! Male Black Howler monkeys typically sound their calls in the morning and then again at night to tell other Howler monkeys where each group's territory is.
