Many summer visitors to the interior of western North America are puzzled when, hiking along the shore of a salt lake, a prairie slough, or an alpine tarn, they hear above them the sound of the sea. Looking up, they may be further surprised when they see a gull soaring, its white underparts gleaming from the reflected light of the water or salt flat below. This gull, far from the ocean, is likely breeding on islands in a nearby lake, for the California Gull is a breeding bird of inland seas.
