This morning I tuned in to see just one left in the box. At first I thought the other two must have fledged. From what I understand, Barred Owl owlets don't return to the box after fledging.Well, now there are all three in the box, so what happened? My guess is that they can stand in the opening and be out of cam view, so it only appeared to be one left. The other remote possibility is that someone put the others back in the box after they left.
