Howell is one of a kind. He is a single species.
Some owls, like the Scops Owls, have over 40 different species throughout the world. Not so with Howell, the Northern Hawk Owl. He has the eyes of a hawk, the long tail and the mean brow of a hawk. He even has the stripey T-shirt of a hawk. But Howell is an owl. He has the specialized facial disc of an owl and the feather taloned boots of an owl.
