The pied avocet (Recurvirostra avosetta) is a rare species, found on the sea shore and in the coastal lakes areas from the Danube's Delta.

It is a migratory species which comes to Romania in March and leaves in October. During mild winters, small groups try to stay in the Delta.

This bird has a smooth and thin, upturned black beak. Its legs are long and its body measures up to 46 cm. Its wingspan is 70 to 77 cm wide. The pied avocet is an elegant bird, with a black and white plumage and bluish legs. The upturned beak of this bird helps it feed using a left-right movement. It feeds on small aquatic animals.

This bird nests in mixed colonies, with other saltwater loving species, such as waders, plovers or seagulls. Its nest is built directly on the ground and it is rudimental. Inside it is coated with a little vegetation. The female lays 3 or 4 eggs in one series each year. Both partner brood the eggs each season. The chicks follow their parents in the water fast and after 5 weeks from hatching they are capable of flying.
