Buenos Aires, Argentina.
Closely related to C. meridae and C. apolinari, and hitherto included C. stellaris. Taxonomy complex, and recent molecular analysis#R found that C. platensis as traditionally constituted is paraphyletic with respect to these other three species; despite most divergence being relatively recent, as many as eight species may be involved, all of them treated here as distinctive subspecies groups. Wide disparities in vocalizations suggest that this finding may gain support in due course; corroborative research urgently needed. Proposed race boliviae (from Santa Cruz, in Bolivia) considered indistinguishable from minimus. Nineteen subspecies recognized.
