Distinguishing Characteristics

Adult male Snowy Plover, breeding plumage, Sanibel Is, FL, February

Color-banded Snowy Plover, Sanibel Is., FL, February

Small plover (15–17 cm long, 34–58 g) with white hind-neck collar and a breast band always restricted to lateral patches. Pale brown upperparts and dark gray to blackish legs also important in identification.

In Alternate plumage, male distinguished from female by black crown, ear covert, and foreneck patches. Many males have a distinct rusty cap at the beginning of the breeding season. Females usually have some to completely brown feathering in one or more of their foreneck patches, and lack rusty caps. A few females with completely black crown, ear covert, and foreneck patches resemble males. In Basic plumage males and females are indistinguishable. Juveniles in fresh plumage are distinguishable from adults by the absence of a forehead patch and by the presence of pale edges on mantle feathers.

Piping Plover (Charadrius melodus) is similarly pale above, but is larger (17-18 cm long) with a thicker, shorter bill, orange legs, and in flight reveals a complete white band across upper-tail coverts; in summer its bill has an orange base whereas Snowy Plover’s bill is all black. Slightly smaller Collared Plover (C. collaris, 14-15 cm long) lacks white hind-neck collar, has dull yellow legs and darker upperparts, and in Alternate plumage has complete breast band. Semipalmated Plover (C. semipalmatus) is larger and much darker dorsally, with breast bands normally complete and legs orange or yellow. Wilson’s Plover (C. wilsonia) has complete breast band, is larger, is darker dorsally, has gray to grayish pink legs, and has longer and heavier bill.

Snowy Plover resembles the Lesser Sandplover (Charadrius mongolus) and Greater Sandplover (Charadrius leschenaultia) of Asia in basic plumage but both these sandplovers lack the white hind-neck collar and are very rare vagrants in North America.
