Bluebird Nest

I finally located their nest. It's an old woodpecker hole in a dead pear tree, in the corner of my back yard. I've had a pair hanging around all day long now for a few weeks. I would sit on my back deck and watch them. I finally got to see where they would go after they had caught an insect. However it still took a couple of days to find the hole in the tree, as it's up about 8 feet. In this pic he's straddling the nest hole.
