Fly over

A while back, before we took the pontoon out for the year, we had a great blue heron do a fairly low fly over.
Ardea herodias
Great Blue Herons congregate at fish hatcheries, creating potential problems for the fish farmers. A study found that herons ate mostly diseased fish that would have died shortly anyway. Sick fish spent more time near the surface of the water where they were more vulnerable to the herons.
