That which we hyphenate as Northern Hawk-owl by any other name would be as sweet. And more correct nowadays, if you spell it Northern Hawk Owl.
But frankly, my dear, we birds don't give a damn what you call us or how you spell or punctuate it. For all I care, you can even call me Surnia ulula. Or how about urniasay lulauay? Scientific pig Latin--how's that for class? But me--I've got more important things on my mind, like puncturing that vole down there. Buh bye!
