Checked a few boxes on our Bluebird trail this evening and was happy and amazed to see that boxes that had a small nest start or were empty 5 days ago now have full nests. One box that I have been watching closely had Mom and Dad hanging tight. They both had bands, uncertain if these birds were banded in 2010 or 2011, nevertheless, happy to see the kids are staying local and starting a family.
Here's a couple low quality images, as I was losing light and a fair distance away but you get the idea.
