Here is a photo of Mr. Blue with some good grub. When the photo as taken, it was one week after I did a nest switchout from an infested nest with blowflies to a clean replacement nest I kept from a previous bluebird fledging–around Day 14 in age. Look into the entry hole closely. You’ll see a bright white dot. That’s a chick inside–the reflection off one of his eyes! I would like to note that there are only TWO boxes on my whole trail that do not have the Noel wire predator guard in front of the entry hole. This is an experiment to see how these two boxes do without them. I like the design better with the box opening in front…you’ll see the amount of ventilation these boxes have at the top of the box by the roof. This is my favorite box design…larger roof and roof overhang, good ventilation, and they stay dry inside during torrential rains. The other boxes are side opening boxes because of the Noel guards are installed over the entry holes. The birds don’t seem to mind the guards, but these boxes seem to be better for photography. All of this effort is worth it.
