Thanks for the info. I looked up Harlan's on the web and if this isn't one I don't know what it might be. Coloring looks right..Would have liked to see it from behind but it bolted and disappeared. The face looks indentical in coloring to the photos of other Harlans. I'd never heard of this Hawk until now. Appreciate the feedback.
just heard back from a couple expert sources on Hawks and they confirmed this is a Light Morph Harlan's Red Tail. One friend also told me you don't seen this very often. Interested to see if anyone else has photographed one now. Good catch.
