Guy said yesterday they were working on the nest on and off all day.
Which means this cannot be all that far behind:
I’m not sure where they have been sleeping all winter, but since they are coming back for a little housing rehab, I’ll be looking at the trees as I head off to work. I pestered the Red Tail expert at the Raptor Center on a regular basis last year. I am already starting my new list of questions as we wait for the babies to arrive.
