Jean, Lee, Noreen and I watched the fly out.  All three owls were in the cavity.  The fledgling flew out early and had to deal with two alarmed Robins, who made a racket around it.  After all three flew out, they went northeast.  One adult stayed behind for a awhile.  They then were in the area near the two pine trees the owls used two years ago.  We heard more calling and the owls went across the drive.
