Some forms currently considered races of present species may prove to merit treatment as full species, e.g. has been suggested that resident ruficollis and S race jota (including “falklandicus”) possibly separate species from mostly migratory N nominate and septentrionalis#R. N populations of nominate race sometimes separated as meridionalis, and lowland populations from S coastal Ecuador to Chile and Falkland Is as falklandicus, but variation seems to be generally clinal. Further study required. Four subspecies usually recognized.

Subspecies and Distribution
  • C. a. aura Linnaeus, 1758 – W North America from SW Canada (E to S Manitoba) and W USA (E to S Texas) S to Costa Rica, also Greater Antilles; in winter S to C South America.
  • C. a. septentrionalis Wied, 1839 – E North America from SE Canada (E Ontario, Quebec) S to SE USA (E from Louisiana); N populations winter S to SE USA.
  • C. a. ruficollis Spix, 1824 – S Central America (S from Costa Rica) and lowland South America; Trinidad.
  • C. a. jota (Molina, 1782) – Pacific coast of South America (S from Ecuador), E Andes, Patagonia and Falkland Is.
  • Introduced (nominate aura) to Puerto Rico.
