The Snowy Plover breeds locally inland in south-central Oregon, eastern California, northwestern Utah, southern Arizona and New Mexico, central Kansas, western Oklahoma, and western Texas (Page et al. 2009). This species is a year-round resident along the Pacific and Gulf Coasts and overwinters along the coast of Louisiana (Sibley 2014). In Montana, the Snowy Plover is an accidental species and has been observed in June and September (Montana Bird Distribution Committee 2012).
