SP
Thick-billed Warbler (Arundinax aedon), known in Korean as 큰부리개개비 has eligible documented records in 6 of South Korea's 17 first-level administrative regions in the current KoreAves evidence projection. The current supporting record sources are GBIF. These records document evidence coverage; regions without eligible records are not interpreted as biological absence, and the counts are not population or abundance estimates.
