I wonder...

I was watching the birds at my feeder hoping to see something new, maybe a bird migrating south for the winter, when I noticed this little guy land on the bluebird nestbox. My eyesight isn't good enough to see that far so I grabbed my binoculars to see what kind of bird it was.

To my delight it was a bluebird. Could this be one of my babies who has come back home? I'd like to think so. He hung around for a while and sat on top of the swing frame for a bit. At one point I believe he was flying with one or two other bluebirds in the field out back but it was hard to see.
