Races appear to group by latitude, with smaller, darker races (humboldti, bipartita, bracki and excelsa) in N and two larger, paler ones (nominate and venturii) in S, but differences actually minor and may in part reflect Gloger’s and Bergmann’s rules; also no clear vocal differences involved#R. Six subspecies recognized.

Subspecies and Distribution
  • C. a. humboldti (Koepcke, 1963) – SW Ecuador and NW Peru.
  • C. a. bipartita (J. T. Zimmer, 1924) – highlands of Ecuador S through coastal slope in Peru to extreme N Chile (Putre, in Arica–Parinacota).
  • C. a. bracki (O’Neill & T. A. Parker, 1997) – Huallaga Valley, in C Peru.
  • C. a. excelsa (Berlepsch, 1906) – S Peru (highlands of Arequipa and Puno) and W Bolivia.
  • C. a. venturii (E. J. O. Hartert, 1909) – NW Argentina Jujuy S to Catamarca; also Córdoba and San Luis).
  • C. a. alaudina (Kittlitz, 1833) – C Chile from Antofagasta S to region of Los Ríos.
