146 PACIFIC COAST AVIFAUNA No. 11 
Status—Common summer visitant to high Upper Sonoran and Transition 
zones on the Pacific watershed, from the San Jacinto and San Bernardino moun- 
tains northward west of the Sierran divides to the Oregon line. More numer- 
ously and widely distributed during migration; although arriving early and re- 
maining late, I have found no instances of occurrence in mid-winter. Breeds 
to the coast as far south as Santa Barbara (Bowles, Auk, xxv, 1911, p. 177). 
In not quite typical form, V. c. ‘‘orestera’’ (Oberholser, Auk, xx11, 1905, p. 244), 
occurs as a summer visitant to the Argus and Panamint mountains, Inyo County, 
and to the Warner Mountains, Modoe County (Mus. Vert. Zool.). Since it is 
only in a small proportion of individuals that satisfactory separation is possible 
to me, there seems to be no violation of subspecific refinement in lumping ‘‘ores- 
tera’’ with lutescens, at least for the present. 
446 (646b) Vermivora celata sordida (Townsend) 
Dusky WARBLER 
Synonyms—Helminthophaga celata, part; Helminthophila celata lutescens, 
part; Helminthophila celata sordida; Helminthophila sordida. 
Status—Breeds commonly on Santa Rosa, Santa Cruz, Santa Catalina and 
San Clemente islands; also on the mainland at Point Loma and Coronado Beach, 
near San Diego (specimen in Mus. Vert. Zool., collected at the former station in 
April, 1908, by F. Stephens; see also Willett, Pac. Coast Avif. no. 7, 1912, p. 95). 
One instance of nesting at Anacapa Island ( Willett, loc. cit.). Occurs in autumn 
and winter on Santa Catalina Island (J. Grinnell, Auk, xv, 1898, p. 236), and 
on the mainland at various points mostly opposite the Santa Barbara group of 
islands: San Diego, Cuyamaca Mountains, Julian, Santa Ana Mountains, San 
Pedro, Los Angeles, Highland Park, and Pasadena (specimens from all these 
localities in Mus. Vert. Zool. and Grinnell coll.) ; also Santa Barbara, April (J. 
Mailliard, Condor, v1, 1904, p. 16), Haywards, Alameda County, January 25 and 
February 8 (Emerson, Condor, vir, 1905, p. 112; specimens, re-examined by me, 
prove typical sordida), and Palo Alto, Santa Clara County, December 29 (spe- 
cimen, no. 1129, in Law coll., examined by me). The latter two localities are 
some 275 miles north of the northernmost of the Santa Barbara islands. 
447 (647) Vermivora peregrina (Wilson) 
TENNESSEE WARBLER 
Synonym—Helminthophila peregrina. 
Status—Only one record: a single specimen, now no. 3177 in Grinnell col- 
lection, taken near Pasadena, September 27, 1897 (Grinnell, Bds. Los Angeles 
Co., 1898, p. 45). 
448 (652a) Dendroica aestiva sonorana Brewster 
Sonora YELLOW WARBLER 
Status—Abundant summer visitant along the valley of the lower Colorado 
River, from below Yuma at least to a point twenty miles north of Picacho (J. 
Grinnell, Univ. Calif. Publ. Zool., xm, 1914, p. 195). The specimen of ‘‘sonora- 
na’’ recorded from Riverside (Brewster, Bull. Mus. Comp. Zool., xu, 1902, p.
