there was but one pair of great horned owls in the forest, and they lived in the deepest shade, having their great clumsy nest in the hollow of a tall tree. you might have walked past it a hundred times and never have guessed that any owls lived there, if you did not notice the round pellets of bone and hair on the grass. they are such hungry fellows that they swallow their food with the bones in it. then their tough little stomachs go to work, rolling all the pieces of bone and hair into balls and sending them back to be cast out of the owls' mouths to the ground.
