March 19, 2016. Harold R. Spencer Bluebird Trail, Nestbox #2. Nest building in progress. This is a Gillwood box built for me by Fred Stille.
If the bluebirds had chosen this nest site, it would have ended in failure. Nestboxes with predator guards are needed for these birds to have success, at least where I live. Image taken along the Harold R. Spencer Bluebird Trail.
