My Mom says it doesn't look like an owl to her. She thinks it might be a hawk. The Only Nikki (from Ravelry) and my Mom have both mentioned Red-Shouldered Hawk so I checked a site Nikki sent me to and I think they're right.
Here are more shots of the Mystery Bird.
One thing I know is that it's not a turkey vulture because they're big and ugly and when they stare me in the eye I see their big, hideous red heads. They won't be arriving until later next week when they're on their way back to Hinckley, Ohio. I wish I were kidding about this. The swallows return to Capistrano. The vultures return to Hinckley.
