Be quiet, he can hear you.

The Great Grey Owl, one of the world's largest Strigiformes,  grows to an average of 24 to 33 inches tall, with a wingspan of almost 60 inches--but only weighs about as much as a quart of milk. Great Greys live in northern Europe and Asia, across Canada,  in Alaska and in the northern Rocky Mountains of the United States.  They  love to eat rodents and other small animals.  In the video below, one of these majestic modern-day raptors reveals how his head can act like a satellite dish to pick up the sounds of tiny creatures, even as they try to hide from him under the snow.
