Great Horned Owl..
They are the pure wild hunters of our world. They are swift and merciless upon the backs of rabbits, mice, voles, snakes, even skunks, even cats sitting in dusky yards, thinking peaceful thoughts.
I have found the headless bodies of rabbits and bluejays, and known it was the great horned owl that did them in, taking the head only, for the owl has an insatiable craving for the taste of brains.
I have walked with prudent caution down the paths at twilight when the dogs were puppies. i know this bird. if it could it would eat the whole world.
Mary Oliver, from her essay, Owls. 1995
