336. (685b) Wilsonia pusilla chryseola Ridgway. Golden Pileolated 

 Warbler. 



Abundant summer resident from the lowlands to at least 8500 feet in the 

 mountains. Rare in winter. Breeds commonly in the willow regions in May, 

 later in the mountains. Noted by J. Grinnell near El Monte, Los Angeles 

 County, from February 16 (1895) to October 27 (1894) (Pub. 2, Pasadena 

 Acad. Sci., 1898, 47). H. S. Swarth saw a bird near Los Angeles, at least 

 once a week from November 11, 1899, until the end of February, 1900 (Condor 

 n, 1900, 31). J. Grinnell found the species common and apparently breed- 

 ing, in willow thickets at the head of the south fork of the Santa Ana River, 

 8000 to 8500 feet altitude in the San Bernardino Mountains, June 27 to 30, 

 1905 (Univ. Calif. Publ. Zool. v, 1908, 34). Extreme nesting dates in the 

 lower country are as follows : Four eggs, fresh, taken by Antonin Jay near 

 El Monte, Los Angeles County, April 21, 1907, and three eggs, incubation 

 slight, taken by J. J. Schneider near Anaheim, Orange County, July 2, 1899 

 (Condor ii, 1900, 34).

 December 27, 1905 (Condor xi, 1909, 102). 



338. (697) Anthus rubescens (Tunstall). Pipit. 



Abundant winter visitant. Often seen in large flocks on ploughed fields 

 and pasture lands. Noted by J. Grinnell near Pasadena as early as August 

 29 (1895) (Pub. 2, Pasadena Acad. Sci., 1898, 47), and by L. Belding at San 

 Diego as late as April 23 (1884) (Land Bds. Pac. Dist., 1890, 223). One 

 bird seen by H. S. Swarth at Los Angeles, May 1, 1899 (Condor n, 1900, 40). 



339. (701) Cinclus mexicanus unicolor Bonaparte. Dipper. 



Breeds along mountain streams from 2000 to 9000 feet altitude. In winter 

 follows the streams down as low as the foothills. Breeds mostly in late April 

 and the first part of May. According to L. Belding does not occur in San 

 Diego County, owing to the absence of suitable streams. R. Arnold took four 

 slightly incubated eggs in Eaton Canon, north of Pasadena, April 22, 1894 (Grin- 

 nell, Pub. 2, Pasadena Acad. Sci., 1898, 47). In June, 1907, I found this bird 

 common along Bear Creek and other streams in the San Bernardino Mountains. 

 Several nests were examined, all of which contained young birds.
