In his play Love's Labour's Lost, William Shakespeare wrote, "Then nightly sings the staring owl." These words certainly apply to any of these big-eyed, big-headed birds, for owls do indeed stare. And in that staring face, we can see some of the owl's adaptations for life in the dark.

Unlike the eyes of other birds, an owl's eyes face straight ahead, like our own, giving the bird binocular vision. Unlike human eyes, however, they do not move in their sockets, so the bird must swivel its head to follow moving objects.

Although owls see well in dim light, most depend on supersensitive hearing when searching for prey. Long-eared Owls have hearing so acute that they can snatch prey in complete darkness.
