This evening I saw four herons standing in a group on the west side of the lake near Frimley station. They were only a few metres from each other. Maybe they were a family? One of them looked smaller and darker than the others.
Yesterday afternoon I saw three of the herons again on the lake near
Frimley Station. The small dark grey heron was stood by itself
and then flew off. Two other lighter grey ones were standing on
another part of lake.
