Formerly placed in genus Dendroica.

Subspecies

There are 6 subspecies1
The eastern (Myrtle) and western (Audubon's) races of this species were once considered separate species. New results indicate that this topic probably will be assessed again soon, and if so, each of the four groups may become full species.

  • Group "Audubon's Warbler"
  • S. c. auduboni - breeds along the Pacific Slope region
  • S. c. memorabilis - breeds from south-eastern British Columbia south (east of the Cascades and Sierra Nevada) to Arizona, New Mexico and western Texas (this form sometimes lumped with auduboni)
  • Group "Myrtle Warbler"
  • S. c. coronata - breeds from north-central Alberta across Canada to the eastern United States
  • S. c. hooveri - breeds from Alaska, northern Yukon, and north-western Mackenzie south to northern British Columbia (this form sometimes lumped with coronata)
