Abstract
"The red-breasted meadowlarks Pezites militaris and P. defilippii come into contact during the breeding season in southern Buenos Aires Province, Argentina. They behave as separate species, with moderate morphological differences and differences in various vocalizations, some of which probably function in species discrimination. A comparison of the morphology of these two species led to an investigation of the taxonomy of all the meadowlarks. Each of the genera Leistes, Pezites, and Sturnella is considered as comprising a single superspecies. Leistes superciliaris is considered a species, as is Pezites bellicosa. The close relationship among the meadowlarks, their monophyly, and the morphological progression they represent warrant considering all meadowlarks as congeneric. Sturnella Vieillot becomes the generic name for the group, necessitating a change in the name of Pezites militaris to Sturnella loyca, because Leistes militaris has priority and becomes Sturnella militaris"--P. 28-29.
