Titi Monkey

Titi Monkeys' Song

 This magnificent specie of monkey developed  an incredible adaptation. Biologist from the University of St.Andrews and of the University of Neuchatel have this specie for years.  They have discovered that these monkeys emit different pitch cries to indicate different type of predators and their emplacement. Christiane Casar and her team from the university of St.Andrews have tried different experiments. First they placed a stuffed Caracara (one of their predator) in a tree, that made the monkeys make a  A pitch calls. Later  the placed a stuffed Oncilla on the ground, that made the monkeys that saw it make a B pitch calls. When they switch the position of the stiffed animals around and the monkeys caracara was on the ground, the monkeys started with at least four A calls before adding B calls into the mix. If the oncilla was in a tree, the monkeys made one A call before switching to a couple of B calls. They are the fist specie of New World monkeys that developed this survival technique.
And that is how singing saves species ;)
