508 (733, part) Baeolophus inornatus murinus Ridgway 
San Disco TirmousE 
Synonyms—Parus inornatus, part; Lophophanes inornatus, part; Plain 
Titmouse, part; Plain-crested Titmouse, part. 
Status—Common resident of the Upper Sonoran oak regions throughout 
the San Diegan district, from Santa Barbara and Ventura counties (where in- 
termediate towards B. 7. inornatus) southeastward to the Mexican line. Not re- 
ported from any of the islands, nor from east of the desert divides. 
509 (733a) Baeolophus inornatus griseus (Ridgway) 
Gray TITMOUSE 
Synonyms—Parus inornatus griseus; Parus mornatus ridgwayi. 
Status—Sparingly resident in the Upper Sonoran zone on desert ranges 
southeast of the Sierra Nevada: Panamint, Grapevine, Inyo and White moun- 
tains, and eastern slope of Sierra Nevada at head of Owens River (A. K. Fisher, 
N. Amer. Fauna no. 7, 1893, p. 138) ; Providence Mountains (F. Stephens, Con- 
dor, v, 1903, p. 105) ; New York Mountain (Hollister, Auk, xxv, 1908, p. 461). 
510 (735b) Penthestes atricapillus occidentalis (Baird) 
OREGON CHICKADEE 
Synonyms—Parus occidentalis, part (?); Parus atricapillus (?); Parus 
atricapillus occidentalis, part (?). 
Status—First definitely established as a member of the avifauna of the 
state by the taking by Miss A. M. Alexander and Miss L. Kellogg of four speci- 
mens (nos. 19403-19406, Mus. Vert. Zool.) on Scott River, Siskiyou County, six 
miles northwest of Callahan, June 10 and 13, 1911. Since two of these speci- 
mens are but partly grown juvenals there can be no question but that this is a 
breeding station for the species. This chickadee has been attributed to California 
several times previously, in all cases most likely through misidentification of P. 
gambeli, as shown by Belding (Condor, vu, 1905, p. 82). 
511 (738) Penthestes gambeli gambeli (Ridgway) 
MountTAIN CHICKADEE

the Sierra Nevada from the Piute Mountains, Kern County, northward; also on 
desert ranges southeast of the Sierras: White, Inyo, Argus, Panamint and Grape-

Warner Mountains, Modoc County (Mus. Vert. Zool.) ; northwest to Siskiyou
