Watching herons fish is fascinating. To see them walk slowly in the water looking very carefully to see if they have dislodged a little fish with their feet is gripping. Brandon Marsh is renowned for its kingfishers but there are a lot more species that deserve a good look. This heron fished in front of the hide for a good hour before flying away.
