indicating a breeding station somewhere in the mountains of southern California. 
427 (620) Phainopepla nitens (Swainson) 
PHAINOPEPLA 
Synonyms—Ptilogonys mtens; Cichlopsis mtens; Black Flycatcher. 
Status—Common resident in the desert regions of southeastern California; 
common summer visitant through the San Diegan district and north locally to 
Alameda County (Pemberton, Condor, x, 1908, p. 238), Chico and Marysville 
(Belding, Land Bds. Pac. Dist., 1890, p. 196) ; also along the western foothills of 
the Sierras through Eldorado County even to Baird and Fort Crook, Shasta 
County (Townsend, Proe. U. 8. Nat. Mus., x, 1887, p. 222), and east of the Sier- 
ras into Owens and Panamint valleys (A. K. Fisher, N. Amer. Fauna no. 7, 1893, 
p. 118). Breeds chiefly in the Lower Sonoran zone. Although this bird rarely 
winters in the San Diegan district, it does winter in numbers on the much colder 
Mohave Desert, and to the northward even to Paicines, San Benito County (J. 
Mailliard, Condor, vi, 1904, p. 16). 
428 (621, part) Lanius borealis invictus Grinnell 
NORTHWESTERN SHRIKE 
Synonyms—Lanius septentrionalis; Lanius borealis; Collurio borealis; 
Northern Shrike; Butcher-bird, part. 
Status—Irregular midwinter visitant into northern California; recorded 
from: Nicasio (doubtful) and Marysville (Belding, Land Bds. Pac. Dist., 1890, 
p. 197) ; Fort Crook, Shasta County, and Shasta Valley, Siskiyou County (Feil- 
ner, Ann. Rep. Smiths. Inst., 1865, pp. 422, 425) ; Quincy, Plumas County (J. 
Grinnell, Pac. Coast Avif. no. 1, 1900, p. 54); Eagle Lake, Lassen County (J. 
and J. W. Mailliard, MS). 
429 (622a) Lanius ludovicianus excubitorides Swainson 
WHITE-RUMPED SHRIKE 
Synonyms—Collyrio excubitoroides, part; Collurio ludovicianus excubitor- 
oides, part; Lanius excubitoroides, part; Lanius ludovicianus gambeli, part. 
Status—Common resident of the desert regions of southeastern and north- 
eastern California, that is, the area east of the Sierran divide. Recorded west at 
the north to Shasta Valley, Siskiyou County (C. H. Merriam, N. Amer. Fauna 
no. 16, 1899, p. 128), and at the south to Palm Springs, Riverside County (J. 
Grinnell, Condor, v1, 1904, p. 43). The shrikes of the Colorado Desert differ 
slightly from those of northeastern California; the status of the various forms 
has not been satisfactorily worked out. The San Diegan district north at least 
to the vicinity of Los Angeles, and the southern San Joaquin Valley, furnish 
specimens variously intermediate between L. 1. excubitorides and L. 1. gambeli, 
probably best referred to under the latter name.
