1915 BIRDS OF CALIFORNIA 151 
465 (68la+681c, part) Geothlypis trichas occidentalis Brewster 
WESTERN YELLOWTHROAT 
Synonyms—Geothlypis trichas arizela; Geothlypis trichas, part; Trichas de- 
lafieldi; Pacifie Yellowthroat, part; Maryland Yellowthroat. 
Status—Common migrant generally through southern California and 
northward both east and west of the Sierras; summer visitant to fresh water 
marsh areas below Boreal, from west-central California (except the San Fran- 
cisco Bay region) to the Oregon line and east to the Nevada line. Occurs in the 
valleys east of the Sierras south at least to the latitude of Death Valley (A. K. 
Fisher, N. Amer. Fauna no. 7, 1893, p. 123) ; specimens from near Lone Pine, 
Inyo County, are distinetly occidentalis (Mus. Vert. Zool.). The systematic 
status of the breeding Yellowthroats of the San Joaquin-Sacramento basin has 
not been satisfactorily determined. 
466 (68le, part) Geothlypis trichas scirpicola Grinnell 
TuLE YELLOWTHROAT 
Synonyms—Geothlypis trichas occidentalis, part; Geothlypis trichas, part; 
Trichas marylandica; Western Yellowthroat, part; Pacific Yellowthroat, part. 
Status—Common resident on fresh water marshes of the Pacific lowlands 
of the San Diegan district: San Diego, Orange and Los Angeles counties (many 
specimens examined), northwest to Santa Barbara (Bowles coll.), and valley of 
the South Fork of Kern River, Kern County (Mus. Vert. Zool.) ; also along the 
lower Colorado River, from Riverside Mountain to the Mexican line (J. Grin- 
nell, Univ. Calif. Publ. Zool., xm, 1914, p. 202). 
467 (681e) Geothlypis trichas sinuosa Grinnell 
Satur MAarsH YELLOWTHROAT 
Synonym—Geothlypis trichas occidentalis, part. 
Status—Common resident locally on salt and fresh water marshes in the 
immediate vicinity of San Francisco Bay. Specimens, in Mus. Vert. Zool. and 
Grinnell ecoll., examined from: Lake Merced, San Francisco County; Palo Alto, 
Santa Clara County; Cerrito Creek, Haywards, San Leandro, and Melrose, in 
Alameda County; Richmond, Contra Costa County; Saint Vincent, Marin Coun- 
ty; Second Napa Slough, Sonoma County. Also Olema, Marin County (one spe- 
cimen, Mailliard eoll.). This warbler is thus exceedingly limited in its range. 
I have seen no examples of intermediate character, which would show intergrada- 
tion with G. t. occidentalis of the nearby regions on the south and east.
