Closely related to A. rutila, but not, as sometimes suggested, to A. tzacatl and A. amazilia alticola. Race cerviniventris formerly treated as a distinct species, including chalconota as a race. Three subspecies recognized.

Subspecies and Distribution
  • A. y. chalconota Oberholser, 1898 – extreme S USA (SE Texas) to NE Mexico (S to San Luis Potosí and N Veracruz).
  • A. y. cerviniventris (Gould, 1856) – E Mexico (Veracruz, Puebla, NW Chiapas).
  • A. y. yucatanensis (S. Cabot, 1845) – SE Mexico (Tabasco, Campeche, Yucatán), N Belize and NW Guatemala; erroneously reported from Honduras. Part of population winters N & NE along Gulf Coast of Texas.
