Grey Heron

There were 6 heron over today the little female (pictured), the adult male, both Jekyll and Hyde, the adult female who may be my original heron and the male with the dark patch. I really wonder how many there are. The little female must have been doing some hunting before she flew over as the shot shows her starting to empty her crop, making room for my fish. 
Ther were only 2 crows today and no sign of the coot.
