The common tawny owl is a medium-sized nocturnal owl with brown or gray plumage. It lives in the forests of Europe and Asia, has excellent vision and hearing in the dark, and hunts small animals.
The tawny owl differs from other owls with its dark eyes and lack of ear tufts on the head. It is important for the forest because it regulates the population of rodents.
