In the last post, I mentioned seeing a hybrid monkey among the Colobus monkeys. The name was so odd that I didn't think I had heard it right! But sure enough, hybrid monkeys exist.
They are the infertile offspring of a Mona and a red tailed monkey (when I uploaded this video to YouTube, I mistakenly wrote it's a blue monkey). Neither of the parents accept the hybrid monkey but, don't worry, the Colobus monkeys are happy to have the hybrid in their troop!
