[Three songs of A. n. nelsoni. The very high, thin "tsip" calls heard throughout this recording were probably given by Passerculus sandwichensis, less likely A. leconteii or another grassland sparrow. They were not given by the singing bird and probably not even by this species (Jon S. Greenlaw email message - 24 March 2005). Quality added (2) - CAM - 11 March 2005]
ML: Subject changed from recordist's original identification of Ammodramus nelsoni nelsoni to Ammodramus nelsoni nelsoni/alter to conform to eBird Taxonomy (v. 1.55). -Jay McGowan/Matt Medler, July 2015.
