1915 BIRDS OF CALIFORNIA 149 
(Mus. Vert. Zool.) ; Argus, Panamint, Inyo, Grapevine, and White mountains, 
Inyo County (A. K. Fisher, N. Amer. Fauna no. 7, 1893, p. 120) ; Providence 
Mountains, eastern San Bernardino County (F. Stephens, Condor, v, 1903, p. 
105). Widely distributed during migration; some individuals tarry late in the 
fall, as November 1 at Berkeley (F. O. Johnson, Zoe, m1, 1892, p. 117). 
457 (667) Dendroica virens (Gmelin) 
BLACK-THROATED GREEN WARBLER 
Status—But one record: female adult taken May 29, 1911, on the Farallon 
Islands, and another seen June 1 of the same year at the same place (Dawson, 
Condor, xm, 1911, p. 168). The specimen secured, and examined by me, is now 
no. 18080 in the collection of the California Academy of Sciences. 
458 (668) Dendroica townsendi (Townsend) 
TOWNSEND WARBLER 
Status—Common migrant through southern and interior California. Casual 
on Farallon (W. E. Bryant, Proc. Calif. Acad. Sci., 2nd ser., 1, 1888, p. 49), 
Santa Barbara (J. Grinnell, Rep. Bds. Santa Barbara Ids., 1897, p. 7), San 
Clemente (Linton, Condor, x1, 1909, p. 194), and Santa Cruz (Linton, Condor, 
x, 1908, p. 128) islands. Also fairly common as a winter visitant in the west- 
central part of the state from Marin to Monterey counties including the San 
Francisco Bay region, more sparingly in the San Diegan district. There have 
been several ascriptions of this bird to the state as a breeding species; but no 
instance so far, that I know of, bears criticism (see J. Grinnell, Condor, vn, 
1905, p. 52). 
459 (669) Dendroica occidentalis (Townsend) 
Hermit WARBLER 
Synonym—Western Warbler. 
Status—Common summer visitant to the Transition zone along the Sierra 
Nevada from the Mount Whitney region to Mount Shasta (several records for 
each extreme). There are in Mus. Vert. Zool. two adult male specimens labelled 
as taken in the San Bernardino Mountains, June 13, 1889; this would appear to 
indicate a far southern breeding station, but the point is not proven. Fairly 
common migrant through southern California both east and west of the Sierras; 
more rare as a migrant north through west-central California: Paicines, San 
Benito County (J. and J. W. Mailliard, Condor, mr, 1901, p. 126); Berryessa, 
Santa Clara County (C. Barlow, Condor, m, 1900, p. 133); Berkeley (Belding, 
Land Bds. Pae. Dist., 1890, p. 215) ; Petaluma (J. G. Cooper, Proc. U. 8. Nat. 
Mus., 11, 1880, p. 246) ; Cahto, Mendocino County (McGregor, Nidologist, 1v, 1896, 
p. 8). Casual on Santa Barbara Island (J. Grinnell. Rep. Bds. Santa Barbara 
Ids., 1897, p. 7). Occasional individuals winter in west-central California: 
Pacific Grove, Monterey County, January 22; San Geronimo, Marin County, 
January 30; both specimens in the Mailliard collection.
