These are the babies. Looks like they're about ready to fly!
And this is the mother with a baby beside her that you can barely see. The light pole itself is very tall, one of those that towers over the ball field.
Yesterday, we saw a large bird on a nearby pole. I theorize he was the father and was acting as sentry for his little family. Or maybe he was looking for tasty squirrels/mice/lizards to feed his growing kids.
Then again, maybe his wife had kicked him out of the nest!
