According to Gabrielson and Jewett (1940) there are to subspecies
that occur in the Pacific Northwest. "Northwestern" Robin (Turdus
migratorius caurinus) and "Western" Robin (T.m.propinquus).

Caurinus is described by Pyle (1997) as small, brown to brownish-
gray upperpart with medium-pale to medium-dark rufous-orange breast
and belly. It has very little or no white tips to the outer

Propinquus is large, pale to medium brown-gray upperparts with
pale to medium rufous without orange tinge. It has very little or
no white tips to the outer rectrices.

Pyle also notes "aleucus" which he calls a clinal variant of
propinquus which is smaller, browner and has less white in
the tail than Rocky Mountain forms.

There is (I'm guessing) a good chance of "Eastern" Robin T.m.migratorius
which Pyle lists as breeding From Alaska to c-BC (presumably east of
the Rockies). It is described as medium in size, medium-brownish to
dark brownish dusky uppers and medium to dark rufous tinged in orange.
Tail spots are medium to large.
