Atypical sylvia warbler songs I

July 2008
Last year a Leipzig based birder pointed me at two warblers with atypical songs.
So we went out to make some sound recordings for documentation purposes.
We identified them phenotypically as Blackcap Sylvia atricapilla and Garden
Warbler Sylvia borin.

070624, Eurasian Blackcap Sylvia atricapilla, atypical song, Torgau, Germany

070624, Garden Warbler Sylvia borin, atypical song, Torgau, Germany
