Not sure if this bluebird actually could tell that someone inside the window was there taking its photo. Maybe the way the sun was, etc, he could tell there was movement. Anyway, it seemed like he noticed me! It was nice to see the bluebirds back. The bluebirds had come back again this year, so I hurried and put their birdhouse outside in its usual spot. Then sparrows started making nests in the house, which I removed the second time. I think the sparrows gave up, because now the bluebirds have taken ownership of the house again.
