A call playback survey of wintering Japanese Marsh Warbler Locustella pryeri was conducted at 32 wet-grasslands within the Kanto Region from late December to early February in 2014-2015 and 2015-2016. We located 94 individuals at 13 survey sites. Four occupied wintering sites were in urban areas that were isolated from other sites. Three sites included abandoned rice fields, and another three sites were maintained as urban ecology parks, suggesting these environments are useful for the wintering warblers. In this study, the Japanese Marsh Warblers were observed in various types of reedbed, suggesting that wintering warblers can use more varieties of vegetation structure than was previously expected.
