84 PACIFIC COAST AVIFAUNA No. 11 
xu, 1914, p. 189). Recorded as far north as Death Valley, Inyo County (Ben- 
dire, Life Hist., u, 1895, p. 157), and west to Witch Creek, San Diego County 
(Bishop, Condor, vm, 1905, p. 142). The latter locality also furnishes specimens 
referable to californicus, and it is probable that the one recorded is at least not 
typical of nitidus. The latter form may, however, be confidently expected along 
the western edge of the Colorado Desert not far east of Witch Creek. 
254 (418b) Phalaenoptilus nuttalli californicus Ridgway 
Dusky Poor-WILL 
Synonyms—Antrostomus nuttalli, part; Phalaenoptilus nuttalli, part; Pha- 
laenoptilus nuttalli nitidus, part; California Poor-will; Nuttall Whip-poor-will. 
Status—Common in summer in the Upper Sonoran zone west of the Sierran 
divide, both in the western foothills of the Sierras and in the coast ranges, from 
Gridley, Butte County (Belding, Land Bds. Pae. Dist., 1890, p. 75) and vicinity 
of South Yolla Bolly Mountain (Ferry, Condor, x, 1908, p. 41), south to the Mex- 
ican boundary, including the west slopes of the Sierra Nevada and the whole San 
Diegan district. Not recorded from the humid coast belt north of Sonoma Coun- 
ty. Occurs locally up into the Transition zone, especially in late summer. Re- 
corded from San Clemente and Santa Catalina islands. Migratory at high alti- 
tudes and northerly, but occurs throughout the winter in the foothill region of 
southern California; taken in January at Paicines, San Benito County (J. and 
J. W. Mailliard, MS). 
255 (420d) Chordeiles virginianus hesperis Grinnell 
Paciric NIGHTHAWK 
Synonyms—Chordeiles popetue; Chordeiles popetue var. henryi; Chordeiles 
virginianus; Chordeiles virginianus henryi, part; Western Nighthawk, part; 
Bull-bat. 
Status—Common summer visitant to high Transition and Boreal zones in 
extreme northern California, from the Warner Mountains, Modoe County (Ober- 
holser, Bull. 86, U. S. Nat. Mus., 1914, p. 50), west to Humboldt Bay (W. K. 
Fisher, Condor, 1v, 1902, p. 132); and along the Sierra Nevada from Mount 
Shasta (C. H. Merriam, N. Amer. Fauna no. 16, 1899, p. 116) south to Trout 
Creek, Tulare County (Mus. Vert. Zool.) ; also, in southern California, on the 
San Bernardino Mountains (J. Grinnell, Condor, vir, 1905, p. 170) ; casual (?) 
at Furnace Creek, Death Valley, June 19, 1891 (A. K. Fisher, N. Amer. Fauna 
no. 7, 1893, p. 53; see also Oberholser, loc. cit.). Noted rarely in migration else- 
where west of the Sierras: Ukiah, Mendocino County (McGregor, Nidologist, 11, 
1896, p. 129); Haywards (Emerson, Bull. Cooper Orn. Club, 1, 1899, p. 28) ; 
Pasadena (J. Grinnell, Bds. Los Angeles Co., 1898, p. 26). Doubtless most of 
the valley records under one or other of the synonyms enumerated above really 
belong to the Texas nighthawk.
