U is for Unexpected Visitors

The keen eyes of a co-worker spotted this little guy hanging out in one of the trees outside our office windows this morning.

I think he's a falcon, but I'm not 100% sure. He's awfully small to be a hawl, unless he's a juvenile, but even for that, it's awfully late in the year for a juvenile still so small. He's also got more white on his tummy than I'm used to the hawks and eagles around here having.

He looks an awful lot like a Peregrine Falcon, but they're endangered in WI, so I'm hesitant to believe that's what he is, especially since I think this guy's got too much white on his tummy. But this area has apparently been the site of at least one releasing in the last 15 or so years, so it's possible.
