NOTES: 48 SONGS. EDGE OF PRAIRIE SLOUGH. BNA: Song (r-r-t'-sz-z-z-t) is heard. CZ 01/06/2004. [Indeed, this recording contains 47 songs of the species. There is also a series of three thin "tsip" calls given at 2:35. Quality changed from 2-1 to 2-3 (would have been 2-1, but all songs with a good signal appear to be overloaded, so only the "weaker" ones are useable) - CAM - 10 March 2005]. Habitat: Wetland, Freshwater, Edge.
