1915 BIRDS OF CALIFORNIA 75 
side of the lower Colorado River above the Laguna Dam, where both the birds 
and their eggs have been taken (Brown, Condor, vi, 1904, p. 45; J. Grinnell, 
Univ. Calif. Publ. Zool., xm, 1914, p. 129). The record from near San Bernardino 
(Loomis, Auk, xix, 1902, p. 80) has been questioned (see F. Stephens, Condor, 
Iv, 1902, p. 45). I consider some doubt to pertain also to that from ‘‘Kern 
County’’ (Ridgway, Condor, tv, 1902, p. 18) . 
226 (385) Geococcyx californianus (Lesson) 
ROAD-RUNNER 
Synonyms—Leptostoma longicauda; Geococcyx affinis; Geococcyx viaticus ; 
Geococcyx mexicanus; Chaparral Cock; Paisano. 
Status—Common resident of the Lower and Upper Sonoran zones on both 
the desert and Pacific slopes. Recorded north, east of the Sierras, to Big Pine, 
Owens Valley (Van Denburgh, Proe. Acad. Nat. Sci. Phila., 1898, p. 209) ; north, 
west of the Sierras, to the head of the Sacramento Valley, nearly 41° latitude, the 
three northernmost stations, all in Shasta County, being: Igo (Belding, Land 
Bds. Pac. Dist., 1890, p. 56), Fort Reading (Newberry, Pac. R. R. Rep., vi, 1857, 
p. 91), and Copper City, ten miles up Pitt River (Townsend, Proe. U. 8. Nat. 
Mus., x, 1887, p. 204). While fairly common, at least formerly, in the San Fran- 
cisco Bay region, the species does not invade along the coast much farther north; 
the northernmost recorded occurrences in the humid coast belt are: vicinity of 
San Geronimo, Marin County (J. Mailliard, Condor, 1, 1900, p. 63), and Sebas- 
topol, Sonoma County (Belding, Land Bds. Pac. Dist., 1890, p. 56). Although 
the roadrunner has been recorded from Santa Catalina Island (Cooper, Proc. 
Calif. Acad. Sci., 1v, 1870, p. 77), there has never been any corroborative evidence 
to this effect ; nor is it known to oceur on any other of the islands. 
227 (387a) Coccyzus americanus occidentalis Ridgway 
CALIFORNIA CUCKOO 
Synonyms—Coccyzus americanus; Coccyzus erythrophthalmus; Yellow- 
hilled Cuckoo. 
Status—Fairly common summer visitant chiefly to Lower and Upper Sono- 
ran zones west of the Sierran divide. The metropolis of the species is in the 
willow association of the river valleys. Recorded north in the coast belt to Sebas- 
topol, Sonoma County (Shelton, Condor, x1, 1911, p. 19), and through the Sae- 
ramento Valley to Fort Reading, Shasta County (Newberry, Pac. R. R. Rep., v1, 
1857, p. 92), and Shasta River (C. H. Merriam, N. Amer. Fauna no. 16, 1899, p. 
114). Recorded east of the Sierras from Death Valley and Owens Valley (A. K. 
Fisher, N. Amer. Fauna no. 7, 1893, p. 45), Needles, on the Colorado River (F. 
Stephens, Condor, v, 1903, p. 101), and Yermo, Mohave Desert (Lamb, Condor, 
xiv, 1912, p. 36). Breeds south at least to Wilmington, Los Angeles County 
(Jay, Condor, xm, 1911, p. 69), and Anaheim, Orange County (J. J. Schneider, 
Condor, 1, 1900, p. 34) ; records of occurrence of individuals at various points in 
San Diego County are as likely to have been of transients as breeding birds.
