Monkeys Found Humping Deer [VIDEO]

Female Macaque monkeys are mounting Sika deer in Japan.

This act has been determined to be sexual in nature because they have other strange sexual habits. This is a new observation that seems to benefit the monkeys by releasing sexual frustrations, and benefit the deer by grooming their backs for ticks and other insects. A recent study showed 13 successful consortships and 8 failed. Of the eight failed, 5 were bucked off. I wish we had a video of that!
