On Saturday the Rangers told me there was a Great Horned Owl visiting the park, and they told me the general area where to find it, and after some searching I found her! Isn't she gorgeous?
As you can see, she blends in very well with the brown and gray colors of a tree in winter. Camouflage is a very important for birds, because they are either being hunted or hunting each other or other animals, and in either case, it pays to not stick out like a sore thumb!
