Taxonomy:

Parus rufescens

J. K. Townsend

, 1837,

forests of Columbia River, probably near Fort Vancouver, Washington, USA

.

Has been considered conspecific with P. cinctus and P. hudsonicus. Genetic study evidenced four main groupings (Queen Charlotte Is; C Alaska; SE British Columbia; and large coastal group) that do not accord with traditionally recognized subspecies#R. Nominate race and neglectus intergrade widely in area formerly occupied solely by latter, which may now be swamped by nominate. Proposed races ferrugineus (Sitka, Alaska), vivax (Prince William Sound) and levyi (Idaho) all included in nominate. Three subspecies recognized.

Subspecies and Distribution
  • P. r. rufescens (J. K. Townsend, 1837) – Alaska, SW Canada and W USA (S to coastal N California).
  • P. r. neglectus (Ridgway, 1879) – coastal C California.
  • P. r. barlowi (Grinnell, 1900) – coast of SW California (S from San Francisco Bay).
