Hi Alan.
Absolutely amazing shots of the Kingfisher, I sometimes get to take similar shots of a local kingfisher, only so far away from the hide that the detail is lost, I spent 40 minutes in one session a couple of weeks ago and when he came close it was almost dark so still no detail. Still great to watch.
The Heron did that lake / river a biiig favour! More nice shots.
Cheers, Graham.
