Habitat

Nests near intertidal zone; coastal bays, river deltas, intertidal shores near forested edges, seabird colonies, and refuse dumps typical of nesting habitat. Feeds in intertidal beaches and reeds, and along tidal pools. Also found in coastal towns, cities, campgrounds, and on agricultural land (Campbell et al. 1997). Obligate tidewater inhabitant (Andres 1999b). Avoids deep forests, but occurs in forest edges (Verbeek and Butler 1999). Winter range similar to breeding range, with flocks from small coastal islands withdrawing to join winter flocks around towns and along beaches (Verbeek and Butler 1999). In B.C., reported from sea level to 1,700 m, but most numerous at lower elevations (Campbell et al. 1997).
