Is That It?

This Red-shouldered Hawk was very far away, too far to get a decent shot with a 400mm lens.  I'm using it as my blip anyway, because I think I have located the nest that I have anticipated all winter.  I've been watching at least one pair, and possibly two, near the creek behind my home, and blipped them several times.  Today there was a great deal of vocalization, and a couple of fly overs.  I watched this hawk fly into the branches, and pick up a leaf in its mouth.  I'm guessing this pile in the fork is a nest in progress.  I sure hope so.  I will certainly be checking it out in the next few days.
