352 (559a) Spizella monticola ochracea Brewster 
WESTERN TREE SPARROW 
Synonym—S pizella monticola. 
Status—Recorded only from northeastern California, where taken by Feil- 
ner at Fort Crook, Shasta County (Henshaw, Rep. Wheeler Surv., 1879, p. 
296; Townsend, Proc. U. S. Nat. Mus., x, 1887, p. 218); Feilner’s specimen, 
still extant, in U. S. National Museum, examined for me by W. W. Cooke Janu- 
ary 31, 1912. Presumably an occasional midwinter visitant to that elevated sec- 
tion of the state subject to severe winters; so conjectured also by J. G. Cooper 
(Orn. Calif., 1, 1870, p. 206). 
353 (560a) Spizella passerina arizonae Coues 
WESTERN CHIPPING SPARROW 
Synonyms—Emberiza socialis; Spizella socialis; Spizella domestica arizo- 
nae; Spizella socialis arizonae. 
Status—Common summer visitant to the Upper Sonoran zone west of the 
Sierras, and of high Transition and Boreal almost throughout the state. Win- 
ters sparingly in the San Diegan district, along the east side of the San Joaquin 
Valley, and more commonly on the Mohave and Colorado deserts, particularly in 
the valley of the Colorado River (J. Grinnell, Univ. Calif. Publ. Zool., xm, 1914, 
p. 170) ; also casually on San Clemente Island (Linton, Condor, x1, 1909, p. 194). 
The point of conspicuous peculiarity about the range of this bird in the state is 
its regular breeding in the orchard districts of the valleys, as in parts of the 
Lower Sonoran zone of Los Angeles County, and also in the coniferous forests 
of the high mountains from Transition to timberline. It breeds in the humid 
coast belt, as at Monterey and near Eureka (Clay, MS), on Santa Catalina Island 
(C. H. Richardson, Condor, x, 1908, p. 68), and on the semi-arid Warner Moun- 
tains and in timberline forests in the vicinity of Mount Whitney (Mus. Vert. 
Zool.). This species thus lives under a remarkable range of both temperature 
and humidity, and yet throughout the state there is no appreciable variation in 
characters.
