Nova Scotia and New York.
Until recently considered conspecific with T. troglodytes and T. pacificus, but differs from latter in characters given under that species and from former in its much lower number of repeat series in song (3); lower average frequency range of individual notes (2)#R; generally plainer (less mottled) breast and upper flanks (ns). Species rank accepted here despite failure to satisfy the Tobias criteria, but this highlights the need for considerable work to clarify relationships in this complex, explore the degree of differentiation among taxa and determine their true species limits. Two subspecies recognized.
