They've flown the coop. The young robins are gone; the parent robins are gone. Just as the online sites about these birds said they would, two weeks after hatching, it was time to fly on.
We were able to see only one of them make the brave move out into the world. Its siblings did it sometime when we weren't looking.
There's the empty nest. That's the closest anyone has been to this nest in a while.
I snapped this photo, moments after observing a sparrow picking bits off the nest and flying off somewhere beyond my line of sight. I guess that's what happens to robins nests?
I felt there must be a lesson in that. I'm not sure if it is a sobering lesson on the transitory nature of life, or a comforting lesson that "all manner of things shall be well," in spite of the transitory nature of life.
