Monkeys vs Flying Squirrel!

Japanese macaques were filmed hanging out, doing whatever monkeys do - until a flying squirrel glided overhead. Then they went, well, bananas, screeching in alarm and pursuing the squirrel like it was a deadly enemy. Researchers speculate the monkeys mistook the squirrel for a predatory bird, but another theory is that the males used the occasion to show off to females how alert and brave they were. In other words, they acted more or less like human males when a female is spooked by a harmless rodent or snake. Guys to the rescue!
