We don't see these as far north as where I live, but the ones I've seen farther south seem to be (as you noted) always on the move - so good job capturing this one in a nice open-wing pose! Good overall sharpness on your subject (the wing tips are just a bit soft, but not a big deal) and I like the diagonal comp and clean background.
Well caught Allen, not easy I am sure. This is easy for me to say but it is not quite there in terms of focus and being sharp, nevertheless a very attractive image.
