The Howler monkey is the loudest monkey and the loudest land animal. The only animal that is louder than the Howler Monkey is the Blue Whale. The Howler's call can be heard up to three miles (4.8 km) away.
The Howler is one of the largest New World monkeys (monkeys from South, North, and Central America). These social primates live high in the trees (the canopy) of the rain forests of Central America, Venezuela, Colombia, Ecuador, Guyana, Brazil, northern Argentina, and Bolivia. Howlers have a life span of about 20 years. These monkeys are in decline due to a loss of habitat.
