This ridge of bone protects the eye from damage when the bird is flying, and also serves as a permanent baseball cap. The two holes in the bird’s beak are the nostrils, or nares. A healthy bird will have intense coloring in the tissue above the beak, in the lips and also the legs and feet.
When you study a red-tailed hawk’s profile, you immediately focus on the huge eyes. These critical organs have internal structures that provide excellent vision. A hawk can see objects 2-3 times better than humans can. Also notice the heavy bony ridge, called a superorbital process.
