A type of monkey that lives in South America, mainly in countries like Brazil and Argentina. It is known for its loud, booming calls, which can be heard from miles away. These calls are one of the most distinct characteristics of the brown howler and are used to communicate with other members of their group and to mark their territory. They have a special voice box and enlarged throat that allow them to make such powerful sounds, which is how they got the name “howler.”

The brown howler is medium-sized, has thick fur, varies in color from light brown to reddish-brown, and has long, prehensile tails. These tails are very strong and act like an extra hand, helping them grasp branches and balance as they move through the trees. They are very slow-moving animals and spend a lot of their time in the trees, rarely coming down to the ground.

Brown howlers are herbivores, meaning they mainly eat plants. Their diet consists mostly of leaves, fruits, flowers, and sometimes seeds. They have large stomachs that help them digest the tough leaves they eat, which many animals would find difficult to process. Because their diet is low in calories, brown howlers spend a lot of time resting to conserve energy. They are known to sleep for up to 15 hours a day, making them one of the more laid-back monkeys in the animal kingdom.

These monkeys live in small social groups, usually made up of a few adult males, females, and their young. They are generally peaceful and stay within their territory. Their loud howling is often heard in the early morning or late afternoon and helps them keep track of where other groups are so they can avoid fights over territory. Despite their impressive vocalizations, brown howlers are not very aggressive and prefer to stay away from trouble.
