Semipalmated Plover

Erika and I found several Semipalmated Plovers at the Nisqually national wildlife refuge on 24 August 2021. This plover is a common shorebird, which breeds across arctic and subarctic Canada and Alaska. The species migrates across most of Canada and the United States, and winters along the hemisphere’s coasts, from Oregon and New Jersey south to Chile and Argentina. A very similar bird, the Common Ringed Plover, occurs in Eurasia. The two species are difficult to tell apart. When I have a photograph, I always look carefully—the Eurasian species is occasionally reported in North America. The birds we saw are definitely Semipalmated Plovers. The dark-color on their lores, the area between their bills and eyes, does not extend to their gapes at the base of their bills.
