To the untrained ear monkeys of a certain species may all sound the same, but Japanese researchers have found that, like human beings, they actually have an accent depending on where they live.

The head winged monkey is called Nikko - also the name of the Japanese town home to the shrine featuring the Hear No Evil, See No Evil, Speak No Evil monkeys.

In ancient Japanese folktales, monkeys often appear as tricksters, cleverly duping other animals out of their rice ball or persimmon fruit.
