Straits of Magellan.
Until recently included as a race of B. virginianus, but differs from the taxon in vocalizations#R and morphology, and also in DNA; in the past, occasionally even merged with B. v. nacurutu. Individuals from higher elevations in Andes have occasionally been separated as race andicolus. Authorship and dating of specific name rather complex: Lesson’s appears to be oldest available name, associated with description; but if homonyms of J. F. Gmelin (1788) and Suckow (1800) are to be considered merely varietal names, some other currently valid bird names, e.g. of Gmelin, might require similar rejection#R. Monotypic.
