Worthen's Sparrow (Spizella wortheni) - HBW 16, p. 559
French: Bruant de Worthen
German: Mexikoammer
Spanish: Chingolo de Worthen
Taxonomy: Spizella wortheni Ridgway, 1884, Silver City, New Mexico, USA.
Sometimes considered sister to S. pusilla; has been considered conspecific, but S. pusilla appears closer to S. atrogularis. Recently published molecular data indicate that present species is sister to S. breweri, suggesting that plumage similarities to S. pusilla reflect convergence; song reminiscent of that of S. passerina, but molecular work suggests that the two are not sister-taxa. Race browni known only from three specimens from type locality (near Sombrerete, in W Zacatecas). Two subspecies recognized.

- wortheni Ridgway, 1884 - SE Coahuila and SW Nuevo León, in NE Mexico.
