Until recently considered conspecific with C. cearae. These two may form a group with C. roberti, C. peruviana, C. ardesiaca, C. castaneiceps and perhaps C. melanogaster. Geographical limits of races uncertain, and S populations of race vulgaris are strikingly different in voice from all other populations (and also from C. cearae)#R; marked genetic structure found in S populations#R may reflect these vocal differences. Proposed forms anomalus from Paraguay (Alto Paraná) and rubecula from Brazil (Veadeiros, in Goiás) respectively subsumed into vulgaris and nominate. Two specimens from E Brazil (Ibiquera, in C Bahia) show distinctive plumage differences, and may represent an unnamed taxon. Two subspecies provisionally recognized.

Subspecies and Distribution

  • C. l. vulgaris Ménétries, 1835 – SC & SE Brazil (S Mato Grosso do Sul and Espírito Santo S to Rio Grande do Sul) to E Paraguay, NE Argentina (Misiones, Corrientes) and E Uruguay.
