hmmm, when the light goes down in the nestbox the phanatics get a little squirrelly ....
BOT one of the adults is parked on the corner of the nestbox - you can see hte outline and the reflecte light from below is lighting up his/her breast some (they are facing inwards). Looking at the size of the outline on the skycam, pretty sure it's Princess. Looks like he does most of the edge sitting during the day, she does it at night.
First feeding will probably be around 0200 hrs (local) or those of you who can't sleep
