Nope. Peregrine is a peregrine. A gyr is a gyr. A coopie a coopie a Red shoulder is a red shoulder. A ferruge is a ferruge. My Nevada ferruges are just the same as the S. Dakota ferruges. But then, I like to keep it simple. Put em in a box if healthy breeding babies pop out 9 months later, bingo! The same thing. Regardless of distance separation, migration and so on. My opinion.
