Previously placed in genus Phacellodomus by some authors. Races vary markedly in size; this, and anomalous pattern of their distribution and unusual combination of habitats, could suggest that the three forms are separate species, although vocal differences seem to be rather subtle#R; further research needed. Three subspecies recognized.
