Distribution of the Japanese Wagtail Motacilla grandis in Korea

Abstract

The Japanese Wagtail Motacilla grandis has been regarded as a near-endemic species of Japan, but recent evidence indicates the existence of a breeding population in Korea. Based on 270 records, four major breeding groups were found to be widely distributed along three major rivers (the Han, Seomjin and Nakdong Rivers) and eastern coastal areas (the Yeongdong area). Due to its habitat preference for streams with sands and gravels, the Japanese Wagtail is a rare species in general, but a locally common resident in Korea.
