Closely related to J. vulcani, but its N populations are genetically very close to J. hyemalis. Usually considered conspecific with J. bairdi. Races form three groups, one represented by nominate and palliatus, the other two being single-subspecies groups formed by, respectively, fulvescens and alticola. These sometimes treated as three separate species; indeed, Guatemala population (alticola) appears genetically well differentiated from all other taxa in genus, and further work may support its elevation to species rank. Race palliatus intergrades with nominate in C Mexico from Nayarit, Durango, Coahuila and Nuevo León S to Guanajuato. Four subspecies recognized.
