Howler monkeys are native to the tropical areas of Central and South America, particularly in the rainforests of places like Brazil, Bolivia and Paraguay. They spend most of their time in the treetops, rarely venturing to the ground.
Also known as New World Monkeys, howler monkeys get their name from their loud cries. A group of howler monkeys calling out makes a commotion that can be heard up to 3 miles away. This is primarily done at the start and end of the day, to let other howler monkeys know that a particular territory is occupied.
Howler monkeys typically spend most of their time up in the trees eating leaves, fruits and nuts, as this is their main source of food. They usually only go to the ground if they need additional water.
