Wilson's Plover Identification Guide

Key Field Marks

• Medium-sized plover (17-19 cm) with sandy-brown upperparts, white underparts, and a single, fairly broad dark breast band (black in males, brownish in females).
• The standout feature is the bill: much larger, longer, and thicker than other "ringed" plovers, giving a distinctly heavy-headed, big-billed look.
• Pale pinkish to flesh-colored legs, duller and less bright than the orange legs of Semipalmated Plover.
• White forehead patch and a dark band through the eye connecting to the ear coverts; lacks the bright orange bill base seen in Semipalmated Plover.
• Sexes are similar but males typically show a more solidly black breast band and dark face mask; females and non-breeding birds are browner overall.

Similar Species

• Semipalmated Plover is smaller with a much smaller, mostly orange-and-black bill, brighter orange legs, and a shorter overall bill-to-head ratio.
• Piping Plover is paler, sandier overall, with an orange bill (black-tipped) and orange legs, and usually shows an incomplete breast band.
• Killdeer is larger with two breast bands (not one) and a much longer tail.
• The oversized, all-dark, heavy bill is the single best mark separating Wilson's Plover from all similarly patterned small plovers.

Habitat & Range

• Breeds locally along the Atlantic and Gulf coasts of the United States, the Caribbean, and both coasts of Mexico and Central America south to parts of South America.
• Strictly coastal: favors sandy and shell-covered beaches, sparsely vegetated dunes, sand flats, and coastal lagoon edges, rarely straying inland.
• Northern populations are migratory, wintering along the Gulf Coast, Florida, the Caribbean, and Central/South America, while southern populations tend to be resident.

Voice

• A sharp, whistled "wheet" or "whit," and a rolling "querrp" alarm call, generally louder and harsher than the softer calls of Semipalmated Plover.

Behavior Notes

• Forages with the classic plover run-stop-peck technique, taking crabs (especially fiddler crabs), insects, and other invertebrates from sand and mud.
• Nests in a simple scrape on open, sparsely vegetated sand, making eggs and chicks vulnerable to beach disturbance and predation.
