The Aquatic Warbler is considered vulnerable and its’ overall breeding range has contracted significantly during recent decades. About 80% of the world population is concentrated to very locally distributed places of the right habitat in NW Ukraine, NE Poland and SW Belarus. Together with some friends I made a weeklong trip to Poland in search for this threatened Warbler. The preferred habitat is open, eutrophic marshes dominated by sedge up to 80 cm tall. Finding these well camouflaged birds is based heavily on knowing their song, but even that proved challenging in areas with large numbers of similarly sounding and looking Sedge Warblers. After two days of searching we found a place with at least five pairs in a well-protected area.
