.

Has been considered conspecific with C. versicolor, but differs in plumage (especially head pattern) and no indication of increased similarity in S of range, where geographically closest. Recent phylogeographic study recovered race melanauris in a clade apart from white-eared birds, but the other two clades within the species did not precisely conform to subspecific limits#R. Three subspecies recognized.

Subspecies and Distribution
  • C. r. melanauris (R. T. Moore, 1937) – Black-eared Red Warbler – NW Mexico in Sierra Madre Occidental from SW Chihuahua S to N Nayarit.
  • C. r. rubra (Swainson, 1827) – White-eared Red Warbler – C & W Mexico (Jalisco SE to N Oaxaca).
  • C. r. rowleyi (Orr & Webster, 1968) – Guerrero and S Oaxaca (S Mexico).
