valleys (A. K. Fisher, N. Amer. Fauna no. 7, 1893, p. 123), along the South Fork 
of the Kern River (Mus. Vert. Zool.), in the lowlands of the San Diegan dis- 
trict (many records) ; thence north, locally common, through the state west of 
the Sierra Nevada; also near Cedarville, Modoe County (Mus. Vert. Zool.). 
469 (685a) Wilsonia pusilla pileolata (Pallas) 
ALASKA PILEOLATED WARBLER 
Synonym—Sylvania pusilla pileolata, part. 
Status—Fairly common migrant through southern California: Santa Bar- 
bara Island, May 14 to 16 (J. Grinnell, Rep. Bds. Santa Barbara Ids., 1897, p. 
8); Pasadena, April 29, May 1, September 22 (J. Grinnell, Condor, v, 1903, p. 
80); Cabezon, May 7, 13 and 15 (J. Grinnell and Swarth, Univ. Calif. Publ. 
Zool., x, 1913, p. 301); Meeea, April 11 and 15; Imperial, May 10; Colorado 
River, April 19 to May 12; Dulzura, April 25; San Diego, May 6; and Julian, 
August 5 (specimens in Mus. Vert. Zool.) ; Yermo, Mohave Desert, April 16 
(Lamb, Condor, xtv, 1912, p. 39). Summer specimens (in Mus. Vert. Zool.) from 
Sugar Hill, eastern Modoe County, are quite typical of pilcolata and indicate the 
breeding of this race within the extreme northeastern corner of the state. The 
subspecies breeding in the White Mountains, near the Nevada line (A. K. Fisher, 
N. Amer. Fauna no. 7, 1893, p. 124) has not been definitely determined, but the 
chances are that this station relates to pileolata also, rather than to chryseola. 
470 (685b) Wilsonia pusilla chryseola Ridgway 
GOLDEN PILEOLATED WARBLER 
Synonyms—Sylvania pusilla pileolata, part; Sylvania pusilla; Wilsonia pu- 
silla pileolata; Myiodioctes pusillus; Myiodioctes pusillus pileolatus; Green 
Black-cap Warbler; Green Black-cap Flycatcher. 
Status—Abundant migrant nearly throughout the state, and common as a 
summer visitant to suitable localities in the Upper Sonoran and Canadian zones, 
from Escondido (Sharp, Condor, vm, 1906, p. 75), and the San Bernardino 
Mountains (J. Grinnell, Univ. Calif. Publ. Zool., v, 1908, p. 116), northward to 
Mount Shasta (Mus. Vert. Zool.), and from the Sierran divide west to the coast. 
This bird furnishes an almost unique instance of interrupted distribution zonal- 
ly; the Transition appears to be taboo, while the zones immediately above and 
below are locally thickly inhabited. 
471 (687) Setophaga ruticilla (Linnaeus) 
AMERICAN REDSTART 
Status—Casual visitant; four definite records: Haywards, male, June 20, 
1881 (Emerson, Zoe, 1, 1890, p. 45); Marysville Buttes, male, June 6, 1884 
(Belding, Land Bds. Pac. Dist., 1890, p. 222); Pasadena, female, December 27, 
1905 (Osburn, Condor, x1, 1909, p. 102); Farallon Islands, male, June 1, 1911 
(Dawson, Condor, xm, 1911, p. 182).
