Pied avocet – Recurvirostra avosetta
is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and western and Central Asia. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is a striking white wader with bold black markings. Adults have white plumage except for a black cap and black patches in the wings and on the back. They have long, upturned bills and long, bluish legs.

These birds forage in shallow brackish water or on mud flats, often scything their bills from side to side in water (a feeding technique that is unique to the avocets). They mainly eat crustaceans and insects.

Their breeding habitat is shallow lakes with brackish water and exposed bare mud. They nest on open ground, often in small groups, sometimes with other waders. 3–5 eggs are laid in a lined scrape or on a mound of vegetation.
