Ardea cinerea
The largest European heron. It can stand with neck stretched out, looking for food, or hunch down with its neck bent over its chest. In flight it holds its neck retracted and has large rounded wings. It is usually solitary although several birds may feed fairly close together. It stalks its food, often standing motionless for some considerable time. It usually feeds close to the bank or shore, but may wade out into shallow water. (Info from www.rspb.org.uk)
