SEMIPALMATED PLOVER NESTING ON THE OREGON COAST

Abstract

In the Pacific Northwest, the Semipalmated Plover (Charadrius semipalmatus) is primarily a migrant, occurring in flocks along the coast during spring migration from mid-April to mid-May, and in fall migration from July through September. Peak numbers occur in late April and late July. Occasional small flocks of non-breeding birds remain through the summer (Paulson 1993) and may be found in suitable habitat in coastal and inland British Columbia, Washington, and Oregon (H. B. Nehls, pers. comm.).
