Perhaps overlooked, this eBird map demonstrates the paucity of North American records. Indeed, the only other records for the lower 48 states are Ninigret Flats, Charlestown, Rhode Island, September 15â€“22, 1991 (Field Notes of Rhode Island Birds 1991); South Lubec Flats, Maine, August 26â€“September 5, 2003 (Ellison and Martin 2004); and Jamaica Bay Wildlife Refuge, Queens, New York, September 13, 2005 (New York State Avian Records Committee 2008).
Observers hoping to find and document one of these should focus on a suite of field marks, including: paler back and upperparts; more pale fringing in the breastband and crown; more slender bill; dark face always meeting at the gape (not above as on most, but not all, Semipalmateds); and lack of toe palmations between the innermost toes. Hearing, describing, and ideally recording the distinctive call is also key.
