Ring-necked Duck
SPRing-necked Duck (Aythya collaris), known in Korean as 북미댕기흰죽지 has eligible documented records in 2 of South Korea's 17 first-level administrative regions in the current KoreAves evidence projection.

These records document evidence coverage; regions without eligible records are not interpreted as biological absence, and the counts are not population or abundance estimates.
