Prey on a spear 

Grey Herons wait ashore motionless or in shallow water for prey. They are characterised by their s-shaped curved neck. If a fish comes close enough, the heron leaps forward with their neck outstretched. They spear their prey with their long beak. This type of fishing is known as "spearfishing". 

Powdered plumage 

Herons have powder down feathers. When rubbed, the dunes fray and produce large amounts of a nourishing powder. As a result, the plumage is greased.
