Avocets feed much like spoonbills, sweeping their bills from side to side along the surface of the water to pick up crustaceans, aquatic insects, and floating seeds. They often feed in flocks, a line of birds advancing abreast, sometimes entirely submerging their heads as they sweep the water for food. During their southward migration every fall, a few American Avocets stray eastward to the Atlantic Coast, where they may be seen singly or in small flocks on shallow lagoons and coastal ponds, where they are uncommon breeders. In the 19th century, there was a small breeding population as far north as southern New Jersey, but they were hunted to near-extinction. They have bred recently on the Atlantic Coast as far north as Virginia.
4 olive-buff eggs, spotted with brown and black, in a shallow depression sparsely lined with grass on a beach or mudflat. Often nests in loose colonies.
