The Netherlands. The Hague. August 29th 2018. The blue heron is a symbol of purity and intuition. The bird is self-reliant and solitaire, but breeds in larger colonies. In the Netherlands the blue heron is a protected birth by law. In their earlier days the blue heron was very shy and lived in the nature far away from the human beings, nowadays the bird is very common in cities and parks as in the 'Zuiderpark' in the Hague.
