Japanese Marsh Warbler Locustella pryeri wintering in Kyushu island, Japan

Abstract

A search for Japanese Marsh Warblers Locustella pryeri was conducted at 86 wet-grassland areas in Kyushu Island, southern Japan, in the winter of 2021–2022, found 16 individuals at seven sites. Wintering sites were found in two regions, along the Japan Sea coast of northern Kyushu and on the Satsuma Peninsula. Abandoned rice fields were the most important habitats. Almost all warblers were found in wet-grasslands with common reeds less than approximately 2 m in height and with abundant understory.
