The fledglings are now accomplished fliers and quickly went all around the Loch this evening.  I lost them for about five minutes, but was able to find them on the east side of the stream.  One of the parents looked like they had been taking a bath.  The young ones were on a branch just a few feet off the ground, and were so close, I had to move back to focus.

As I was about to leave, I heard the trill call again, and one of the parents had what might have been a mouse.  Earlier, there were Whinny calls and the Hoot-Hoot calls to warn of two raccoons.
