Owls have excellent vision. But, do they have four eyes? The two species of pygmy-owls found in the US have a unique adaptation. The back of the head shows two large eye-shaped patterns believed to offer it protection from larger predators that may approach from behind. These small owls are daytime hunters, specializing on other small birds. So, while the pygmy-owl is looking ahead for its prey, the “eyes” on the back of its head deters a predator, fooling it into thinking it is being watched. (video by ktbirding.com)
