Also, Mark reported that three ravens chased a hawk out of the yard today.

I got up early because I was worried that the fledgling might still be on my bike and therefore I'd have to walk and take two buses to work instead of riding my bike. It had, in fact, slept on my bike all night. The bird watched me come out the door. When I closed the door, it ruffled it's feathers and flew alway--all the way across the yard to another building. By the time I came home, everyone had fledged.
