Hawk, again

This time, she was at the bottom of the driveway, perched on a fencepost beside our mailbox.  I was able to drive up fairly close before it took off and flew across the yard, within feet of the house, and back into the ravine behind the house.  I heard it calling while I was in the barn doing my morning chores.  We think she is an immature Redtail - I say she because she is pretty large.
