Roger Anderson was filming his journey through the jungle when a noise startled him and his companions. The gnarly sounding noise that Roger caught on film seems like it belongs in a horror flick!
The horrific noise was coming from the vocal cords of a Howler Monkey! I think the creepiest part of the video is the fact that Roger never did actually see the monkey.
If you have never heard a Howler Monkey in action…you have to check out the video below! Seriously…the sound is haunting!
If you have never heard a mountain lion screaming…check this out!
