Only later did I find out it was a howler monkey calling the rest of its troop. Before leaving, I had studied howler monkeys. I knew they made a loud roar, but nothing could have prepared me for my first real encounter.
A Howler Monkey is the largest monkey found in the Americas, weighing about 15 lbs. They can grow to be 2 feet tall, but have a tail that is as long as their body.
Howler Monkeys are arboreal, meaning that they spend their whole lives in the tree tops. Howlers are also diurnal, meaning they're active during the daytime.
We will try to record the roar next time we hear howler monkeys. Until then, you can check out the following web sites for more information.
