 Chickadee. 



Cumnion resident of the coniferous forests of the mountains from 5000 feet 

 to as high as 10.600 feet ( Grinnell, Univ. Calif. Pub. Zool. v, 1908, 124). Oc- 

 casional to the oak regions of the foothills and mesas in winter. Noted by H. S. 

 Swarth as rather common in winter near Switzer's Camp in the Arroyo Seco. 

 Several birds seen by J. E. Law in the Calabasas Hills, Los Angeles County, Sep- 

 tember 15, 1911. and a male taken by Mr. Law in the city of Pomona, March 6, 

 1901. Several birds seen and one specimen taken, by F. E. Blaisdell at Poway, 

 San Diego County, February 15. and noted by W. O. Emerson in the Volcan 

 Mountains on February 24 and occasionally afterwards ( P)elding. Land Eds. Pac. 

 Dist., 1890, 241). I found it breeding plentifully at Bear Valley, 6750 feet in the 

 San Bernardino Mountains, in June, 1907. Several nests were examined, all of 

 which contained young. J. Grinnell took five slightly incubated eggs in the San 

 Bernardino Mountains, June 15, 1906 (Univ. Calif. Publ. Zool. v, 1908, 124).

feet on brushy mountain sides. Breeds in the lower country mostly in April and 

 May, later at higher altitudes. Extreme nesting dates are : Two sets of fresh 

 eggs taken by N. S. Goss near San Diego, March 16, 1884 (Belding, Land Bds. 

 Pac. Dist., 1890, 242), and four considerably incubated eggs taken by J. Grinnell 

 near Pasadena, June 25, 1897 (Pub. 2, Pasadena Acad. Sci., 1898. 50). 



362. (743a) Psaltriparus minimus californicus Ridgway. California 

 Bush-Tit. 



Abundant resident from the willow thickets of the lowlands up to more than 

 5000 feet in the mountains. Occurs as high as 7500 feet after the close of the 

 breeding season. Common in winter on the Santa Barbara Islands. Breeds 

 mostly in April and May. Extreme nesting dates are : Four eggs, fresh, taken 

 by C. E. Groesbeck near Pasadena, INIarch 7. 1896. and seven eggs, fresh, taken

363. (748a) Regulus satrapa olivaceus Baird. Western Golden- 

 crowned Kinglet. 



Fairly common fall and winter visitant to the mountains, south at least to 

 the San Bernardino Range. Occasionally straggles to the mesas. J. Grinnell 

 took two specimens in Santa Ana Canon, San Bernardino Mountains, at an alti- 

 tude of 5500 feet, August 19, 1907 (Univ. Calif. Publ. Zool. v. 1908. 126). Mr. 

 Grinnell also took specimens on Mt. Wilson. Los Angeles County. October 31, 

 1896, and observed others in the same locality, October 30, 1897 (Pub. 2, Pasa- 

 dena Acad. Sci., 1898, 50). H. S. Swarth found it fairly common in the x\rroyo 

 Seco, above Pasadena, October 19 to 26, 1900, and saw several flocks in San 

 Antonio Caiion, October 18, 1903. He has several specimens taken on Mt. Wil-
