- Charadrius placidus
18–21 cm. (7-8¼ in.)
This rather elegant species is similar to Common Ringed Plover, Semipalmated Plover and Little Ringed Plover but generally larger, with longer dark bill, it is generally less compact. It has a longer tail and medium length straw-colored legs. Sexes are alike, but breeding male has a broader black forecrown bar. Juvenile similar to adult but has buff fringes to the upperparts, tertials and wing coverts and has a more diffuse head pattern lacking the black forecrown bar of adults.
Within range, likely to be confused only with Common Ringed Plover or Little Ringed Plover. Latter is much smaller with much stronger, more obvious bright yellow orbital ring and more obscure wing stripe in flight. Former has much broader black breast-band, orange legs and more obvious white wing strip in flight.
Breeds in gravel, shingle or stony areas at edges of rivers and lakes up to about 1,000 feet. Also occurs in dry rice fields.
