The Silent Watcher

Back blipping a heron from yesterday.  I'm behind as yesterday was a bit of a killer day, with two long patrols at a distance: heavy traffic, multiple roadworks, on the road before 7am.  That's on top of everything else I needed to get done.  So today I'm taking things rather more gently.

I've heard the heron described as the "silent watcher" and that sounds like a pretty good description.
