Trick, Track, Trek Howler Monkey Antics

This morning we tracked a group of howler monkeys trekking and they pulled some tricks on us. We have an amazing video to show what happened after they attempted to surround and ambush us. Stay tuned!

Apparently, when howler monkeys feel threatened by humans who enter their territory the males become aggressive. Today, the monkeys went into the tree canopies over our heads and shook the branches. At that point leaves and branches fell to the ground around us and the monkeys urinated above us. That liquid that splattered from the treetops wasn't rain!

Brian and Roger collected data on the frequency and type of howler monkey calls in 2 minute intervals for 40 minutes, but the study was abruptly ended due to monkey antics.
