Status—Common resident of wooded localities, mostly in the Upper Sonoran 
zone, in southern California (San Diegan district) west of the desert divides and 
north along the west flank of the Sierra Nevada (probably this race) to the 
vicinity of Mount Shasta (C. H. Merriam, N. Amer. Fauna no. 16, 1899, p. 114). 
The areas of intergradation between quercinus and the humid coast form ben- 
direi probably lie in the vicinity of Monterey County and at the head of the Sae- 
ramento Valley (see J. Grinnell, Auk, xxxm, 1915, p. 60). Not definitely re- 
corded from anywhere on the desert or Great Basin slopes.

the neighborhood of Needles to the Mexican boundary (J. Grinnell, Univ. Calif. 
Publ. Zool., x11, 1914, p. 128). Probably occurs also in the Imperial Valley (see

Status—Rare resident along the Sierra Nevada and on the San Bernardino 
Mountains; probably breeds in the Canadian zone, dropping to lower levels in 
winter. Definitely recorded as follows: Fort Crook, Shasta County, one speci- 
men (J. G. Cooper, Orn. Calif., 1, 1870, p. 422); Big Trees, Calaveras County, 
August 16, one specimen (Belding, Proc. U. S. Nat. Mus., v, 1883, p. 549) ; San 
Bernardino Mountains, at least five specimens, May, June, July and January 
(Hasbrouck, Auk, x, 1893, p. 260; T. S. Palmer, Auk, x1, 1894, p. 78; Oberhol- 
ser, Ornis, x, 1899, [separate, repaged] p. 12; Gilman, Condor, tv, 1902, p. 86; 
F. Stephens, Condor, tv, 1902, p. 40; J. S. Dixon, Condor, vi, 1905, p. 140; J. 
xrinnell, Univ. Calif. Publ. Zool., v, 1908, p. 59); Monache Meadows, Sierra 
Nevada, Tulare County, adult and young, August 4 (Mus. Vert. Zool.). All 
records of the so-called ‘‘ Dwarf’’ Sereech Owl are included here, as the status of 
““idahoensis’’ is questionable (see p. 182).
