SP
Sakhalin Leaf Warbler (Phylloscopus borealoides), known in Korean as 사할린되솔새 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 and EcoBank. These records document evidence coverage; regions without eligible records are not interpreted as biological absence, and the counts are not population or abundance estimates.
