PACIFIC COAST AVIFAUNA No. 7 



took a set of three eggs in the Cuyamaca Mountains, San Diego County, June 5, 

 1889 (Bendire, Life Hist. N. Am. Fids., 1895. 283). 



215. (462) Myiochanes richardsoni richardsoni ( Swainson). Western 



Wood Pewee. 



Common summer resident of the canons and the oak and coniferoi'..^ forests, 

 up to 9000 feet in the mountains. Occasional on the Santa Barbara Islands. 

 More or less common, during migrations, along streams and in wooded localities 

 in the lowlands. Eggs are generally deposited during the latter part of May and 

 the first part of June. J. Grinnell observed the species in the vicinity of Pasa- 

 dena from April 18 (1895) to September 30 (1894) (Pub. 2, Pasadena Acad. 

 Sci., 1898, 30). Mr. Grinnell took an adult female on San Nicolas Island, May 

 20, 1897, and an adult male May 12,, following (^Pub. 1, Pasadena Acad. Sci., 

 1897, 10). He also saw one bird on San Clemente Island, June 3, the same year 

 (Pub. 1, Pasadena Acad. Sci.. 1897, 15). H. J. Lelande took three fresh eggs 

 near Pasadena, May 1, 1899, and H. A. Gaylord took three slightly incu- 

 bated eggs in the same locality, July 11, 1894 (Grinnell, Pub. 2, Pasadena 

 Acad. Sci., 1898,30). 



216. (464) Empidonax difficilis difficilis Baird. Western Flycatcher. 

 Common summer resident of the canons in the foothill and mesa regions; 



also on the larger Santa Barbara Islands. Found all over the lowlands during 

 migrations. L. Belding saw one bird at San Diego in December (Land Bds. Pac. 

 Dist., 1890, 99), so it may occasionally winter within our southern limits. Breeds 

 mostly during late May and early June. J. Grinnell has noted the species in the 

 vicinity of Pasadena from March 30 (1896) to October 10 (1896) (Pub. 2, 

 I'asadena Acad. Sci., 1898, 30). FI. S. Swarth took a male near Los Angeles, 

 March 21, 1899, and J. G. Cooper saw the species at Saticoy, Ventura County, 

 March 18, 1873 (Auk iv, 1887, 92). J. Grinnell took four considerably incubated 

 eggs near Pasadena, May 11, 1895, and took four slightly incubated eggs in the 

 same locality, June 29, following ( Pub. 2, Pasadena Acad. Sci., 1898, 30). 



217. (466) Empidonax trailli trailli (Audubon). Traill Flycatcher. 

 Common summer resident from the willow thickets of the lowlands to more 



than 5000 feet in the mountain canons. Occurs in migrations as high as 8000 

 feet. Breeds most plentifully in June. Noted by J. Grinnell at Pasadena from 

 May 4 (1895) to September 26 (1896). A. I. McCormick took three slightly 

 incubated eggs near Los Angeles, May 25, 1895. and H. A. Gaylord took three 

 slightly incubated eggs near Pasadena, July 11, 1894 (Grinnell, Pub. 2, I'asadena 

 Acad. Sci., 1898, 30). 



218. (468) Empidonax hammondi (Nantus). Hammond Flycatcher. 

 Common migrant, mostly to the canons and mesas along the base of the 



mountains. Has been recorded as nesting in southern California but all such 

 records are probably referable to the next species. B. W. Evermann took a speci- 

 men at Santa Paula, Ventura County. April 10 (Auk in. 1886. 180). H. A. 

 Gaylord noted it in the spring near Pasadena from April 9 (1896) to May 9 

 (1896), and J. Grinnell noted it in the fall in the same vicinity from the first week
