We had a pair of red-shouldered hawks nesting in a tree on the grounds last summer, and we've been hoping like crazy they would come back this year. We know it's likely, but I'm feeling more confident now because we've had one hanging around for a couple of weeks. I think it's the male, scoping his old territory and defending it from any possible invaders.
I got some good shots of him today.
Here's my set of photos on Flickr.
