As the eclipse reached its peak (about 70% here), the gray squirrels whined nonstop (their whines are annoying compared to red squirrel complaining). I was surprised they were so sensitive, as the maximum darkness was similar to the atmosphere when a storm is coming, nothing more. Turns out they had more to whine about. I looked out an upstairs window for a squirrel and saw a juvenile red-tailed hawk sitting on our mailbox post. Giant! I ran downstairs and stepped quietly out on the porch. It took a few long seconds before the hawk flew off (pooping first, see photo 3). I'm pretty sure it was a juvenile, but, boy, was it BIG! Maybe it was waiting for the eclipse peak, which happened about 10 minutes later.
