The Black Howler Monkeys might be monkeying around the Belizean #rainforest, but don't let their laidback lifestyle fool you. 🐒 These neighbors of ours aren't gossipers, but their name is their claim to fame - they are the loudest of all monkeys, and their unsettling roars can be heard for up to 3 1/2 miles. They call to let others know where their territory is, alerting them to stay away.
