Range. - Western North America, breeding in the interior.

A smaller Gull than the Herring with the primaries grayish instead of black; length twenty-five inches. This Gull is found in winter on the coast from British Columbia southward to Lower California, but nests in the interiar from Utah northward. They nest very abundantly around the Great Salt Lake, placing their nests generally upon the bare ground. Sometimes there is a scant lining of grasses or weeds and again the nests will be situated in the midst of a tussock of grass. Three or four eggs generally constitute a set, but occasionally five are laid. The usual nesting time is during May. They show the same great variations in color and markings common to most of the Gulls. Size 2.60 x 1.80.
