Documentation: Specimen: UNSM ZM7313, 20 Apr 1901 Havelock, Lancaster Co.
Taxonomy: This species and Nelson’s Sparrow were moved from Ammodramus to the new genus Ammospiza based on genetic studies that indicated former Ammodramus was paraphyletic (Chesser et al 2018).
No subspecies are currently recognized (Pyle 1997).
The correct spelling “LeConte’s” was discussed by Chesser et al (2017).

Winter: This species winters regularly in southeast Kansas (Thompson et al 2011) and there are several Dec-Feb reports for Kansas on eBird, all within the last few winters (eBird.org, accessed April 2018), suggesting that wintering birds may soon be expected in southeast Nebraska.
