Guide to Boreal Birds
The largest of American "eared" owls, the Great Horned is exceeded in size only by the rare Great Gray Owl. The Great Horned Owl preys on a wide variety of creatures, including grouse and rabbits as well as beetles, lizards, frogs, and birds, including crows, ducks, and other owls. On occasion, it even captures skunks. It is the largest and best known of the common owls. It is one of the first birds to nest, laying its eggs as early as late January, even when there is still snow on the ground.
