HabitatOpen sandy beaches, islands, shell or gravel bars, mudflats, estuaries, lagoons, sheltered bays, coastal marshes, and broad rivers or large inland lakes. Nesting sites are sparsely vegetated open ground near productive shallow water.
BehaviorSocial and colonial; rests and nests in flocks on open ground. Forages by flying low over calm water with the elongated lower mandible slicing the surface, snapping the bill shut when it contacts a small fish. Active by day and often at dusk or night; calls are short, barking notes.
