Not Quite a Bluebird

I returned to Blue Mash Nature Trail today, hoping to catch a bluebird.  I was greeted by a flock of noisy crows.  It was difficult to hear or see other birds at first, but eventually they moved on.  There weren't as many birds in general today, but I did manage to find a hawk.  It was too far away for my lens, but I gave it a good try.  My best photo today was of this American Robin.
