Common Potoo, PeruPotoos are really odd looking birds. But cool looking too in their own comical sort of way. They have big, bulbous yellow eyes that resemble colored ping pong balls. This guy was perched high in a tree, where they spend most of their time. They are nocturnal, but occasionally can be spotted sleeping on an open branch during the day. In this image, you can see the potoo’s right eye in profile as he looks toward the right side of the frame.
