The male was back in the nest cavity today.  He flew out in fairly bright light.  I wonder if he’s got a job to do?

The female appeared and I couldn’t tell if she flew out or went back into the cavity.  There was a small bit of gray, left in the cavity, which could have been her head, a feather or a nestling?  At this point I’m confused.  I can’t wait for this puzzle to be solved.
