They’re loud, proud and are ready to howl. This magnificent, noisy troop are the Amazon Rainforest’s alarm clock, except there’s no hitting snooze when they start singing!

How loud is a Howler Monkey?

Their howlers are so loud, they can be heard from four kilometres away! The remarkable level of noise these monkeys generate makes them not only the noisiest of all monkeys, but of any animal stepping foot on the land today.

What makes a Howler Monkey howl?

These brilliant bawlers have such a loud voice thanks to an enlarged hyoid bone in their throats. These huge vocal chambers make turning it up to eleven an absolute breeze. Their howling isn’t them practising for the next season of X-Factor though. Their loud voice comes in very handy warning troops that they aren’t welcome in this patch. As well as a defence strategy, it’s also a way for them to communicate amongst one another within their own troop.

Big Bawls vs Big Balls

Research has found that the hyoid bone is larger in those monkeys who have the louder voice. However, the monkey’s with the smaller hyoid bone and therefore donning a more timid sound in comparison boast larger testicles. Sorry Mr. Howler, you can’t have it all!

Are Howler Monkeys endangered?

Yes. Species like the Black Howler Monkey are at serious risk of being extinct. Their habitat is destroyed at an alarming rate due to deforestation. They are also hunted for both food and sport. It’s a sad truth that resonates with many species endemic to the region who face growing threats to their existence on this planet.
