1915 BIRDS OF CALIFORNIA 93 
278 (469) Empidonax wrighti Baird 
Wricut FLYCATCHER 
Synonyms—Empidonax obscurus, part; Empidonax griseus, part; Empt- 
donax canescens, part; Gray Flycatcher, part. 
Status—Common summer visitant to high Transition and Canadian zones 
along both slopes of the Sierras, from Mount Shasta south to the Mount Whitney 
region; also to the innermost northern coast ranges: South Yolla Bolly and Mt. 
Sanhedrin (Mus. Vert. Zool.), to the Warner Mountains, Modoe County (Mus. 
Vert. Zool.), and to the San Gabriel, San Bernardino, San Jacinto and Santa 
Rosa mountains of southern California (Mus. Vert. Zool.). There are authentic 
breeding records from all the above indicated areas. Occurs sparingly in migra- 
tion through the valleys both east and west of the Sierras, but not at all in the 
coast region of central and northern California. 
279 (469.1) Empidonax griseus Brewster 
Gray FLYCATCHER 
Synonyms—EHmpidonax obscurus, part; Empidonax wrighti, part; Empido- 
nax canescens, part; Wright Flycatcher, part. 
Status—Fairly common transient and winter visitant in the valleys of the 
San Diegan district, where recorded from a number of localities northwest to 
Saticoy (J. G. Cooper, Auk, iv, 1887, pp. 85, 92), and Ventura (Baird, Brewer, 
and Ridgway, Hist. N. Amer. Bds., m1, 1874, p. 520); also on the southeastern 
deserts, as along the Colorado River (J. Grinnell, Univ. Calif. Publ. Zool., x11, 
1914, p. 153), north to Goffs, eastern San Bernardino County (Hollister, Auk, 
xxv, 1908, p. 459). I am much puzzled by the occurrence of this species in so 
consistently typical form in migration, and then apparently disappearing. For 
I now doubt that the breeding flycatchers from the high San Gabriel, San Ber- 
nardino and San Jacinto mountains can be properly referred to griseus, but 
believe they are wrighti (see Grinnell and Swarth, Univ. Calif. Publ. Zool., x, 
1913, pp. 257-259). Typical griseus does not seem to have been authentically 
reported in summer north of the Mexican boundary, and the possibility presents 
itself that the species is like Pyrocephalus and Passerculus rostratus which breed 
south and come north for the winter! 
280 (471) Pyrocephalus rubinus mexicanus Sclater 
VERMILION FLYCATCHER 
Synonyms—Pyrocephalus rubineus; Pyrocephalus mexicanus; Red Fly- 
catcher. 
Status—Common resident in the mesquite belt of the Colorado desert; 
northwest through the Imperial valley at least to Torres, Riverside County (Mus. 
Vert. Zool.), and north along the Colorado River to Needles (J. Grinnell, Univ. 
Calif. Publ. Zool., xm, 1914, p. 153). Winters regularly but in small numbers, 
to the westward in the lowlands of the San Diegan district, from which there 
are many records, from San Diego (J. G. Cooper, Auk, 1v, 1887, p. 92) northwest
