THE SIERRA HERMIT THRUSH. 237 
from Cross Sound; southward in winter as far as Texas and western Mexico, 
migrating chiefly coastwise. 
Range in Washington.—Spring and fall migrant west of the Cascades. 
Migrations.—Spring: ‘Tacoma, April 15, 1905 (J. H. Bowles). Fall: Seattle 
Sept. 21, 1907 (Jennie V. Getty). 
Authorities—Bowles and Dawson, Auk, XXV. Oct. 1908, p. 483. 
Specimens.—P( Alaskan). Prov. B. 
ABOUT all we can certify to, so far, is that there are two varieties of the 
Hermit Thrush which may be seen on Puget Sound during the migrations: a 
lighter and grayer form, presumably from northwestern Alaska; and a darker, 
more warmly-tinted bird, H. g. nana, which may or may not summer to some 
extent in western Washington. Specimens so far encountered in eastern 
Washington are probably H. g. sequoiensis, en route to or from their breeding 
haunts in the high Cascades; while if any are ever captured in the mountains 
of Stevens County, they will probably prove to be of the H. g. audubomi type, 
which prevails in the eastern portion of British Columbia.
