Proposed race amazona (Guianas, N & EC Brazil), described from very few specimens, appears to be not reliably distinguishable from cerula in larger series of specimens. Five subspecies recognized.

Subspecies and Distribution

  • C. f. leucophrys Berlepsch, 1907 – NC Colombia (Sucre E to Magdalena Valley) and NW Venezuela (base of Sierra de Perijá S to Táchira and W Mérida, and SW Lara).
  • C. f. magnirostris E. J. O. Hartert, 1898 – SW Ecuador (W Pichincha S to Guayas and El Oro).
  • C. f. cerula Wetmore, 1939 – locally E of Andes in Colombia, Venezuela, the Guianas, N Brazil (NW Amazonas and R Branco E to Amapá), NE Ecuador, NE & SE Peru and N Bolivia.
