.

With F. canadensis, previously awarded genus Canachites. Hitherto treated as conspecific with F. canadensis, but differs in all-dark vs broad orange-buff tips of rectrices (3); bold white (vs all-dark) tips of elongate uppertail-coverts (3); thin broken vs strong continuous white line across breast (1); broader rectrices (effect size based on published data#R 1.67; score 1); possession of wing-clap territorial display vs none#R (3); moreover, long zone of hybridization occurs at boundary, where two taxa inhabit different habitat (franklinii in montane conifers, canadensis in taiga#R) (2). Validity of recently described race isleibi supported by genetic data#R. Two subspecies recognized.
