The call is a single, insect-like, warbling buzz, lasting about a second.

Sedge meadows, wet prairies, grass or sedge marshes with tall shoreline vegetation

The Minnesota Ornithologists’ Union All Seasons Species Occurrence Map

New World sparrows were traditionally combined with buntings into the family Emberizidae. Recent phylogenetic analysis (Barker et al. 2013) and mitochondrial DNA (mtDNA) analysis (Klicka et al. 2014) found that the Old World buntings should be separated as a sister to New World sparrows. New World sparrows have been separated into a new family, Passerellidae.

This species and Saltmarsh Sparrow were originally thought to be one species, Sharp-tailed Sparrow (Ammodramus caudacutus). In 1998, the species was split. The Saltmarsh Sparrow retained its scientific name and this species became Nelson’s Sharp-tailed Sparrow (Ammospiza nelsoni). In 2009 the common name was simplified to Nelson’s Sparrow.
