We stopped to listen to the family on Tuesday May 31 and were rewarded by some sneak peeks at beaks:
Mom arrived to a cacophony of eager cheeps:
After mother leaves a little one peers out with one eye…
A little further …
Then a good look outside at a guy with a long lens!
I suspect that this family is close to fledging. We shall have to monitor the nest closely now.

Hi Krys,
Yesterday, June 4th, I couldn’t hear any cheep cheep so I think that they might have fledged.
