I've been unable to watch the owls for a week. Tonight, Jean, Chris and I only saw two owls. It's the right number of weeks for "natal dispersal" to have occurred, so it's possible that the youngster is now off on its own.
I learned later this evening that the NYC Park Rangers released the three rescued fledglings back into the park near where the nest cavity had been, within an hour of my taking these pictures. Over the next few days, we should learn if the parents accept their young back, ignore them or are hostile to them. It should be an interesting week.
