Subspecies

Eastern Meadowlark (Sturnella magna) (Sibley and Monroe 1990, 1993) and Lilian's Meadowlark (Sturnella lilianae) (Sibley and Monroe 1990, 1993) have been lumped into Sturnella magna following AOU (1998), who note the two groups differ in plumage, morphology, and habitat preferences (Lanyon 1962, Rohwer 1972, 1976), but are quite similar in vocalizations (Lanyon 1962).
Thought to form a superspecies with Eastern Meadowlark (Sturnella magna), the two being geographically separated by distributional gaps. Previously treated as conspecific with Eastern Meadowlark (Sturnella magna), but differs vocally and morphologically. Also, recent DNA data from mitochondria and the sex-linked Z chromosome revealed a deep genetic divergence, supporting treatment as two distinct species. Some subspecies currently included in Eastern Meadowlark (Sturnella magna) (notably auropectoralis) may belong with present species. Detailed genetic and morphological analysis of all Mexican breeding populations needed.
Considered by some authors to be a subspecies of Eastern Meadowlark (Sturnella magna).
