Here are the range maps from our Great Gray Owl book, feel free to use and copy. Please give us credit as these are original maps based on our research. I hope in twenty years new maps will show that there are owls in some of the interstices and that the species is thriving. Much of this information came from direct witnesses including many helpful biologists with federal and state agencies.
We have provided much needed information for the wikipedia entry on this species, Check it out here.
