(,2 PACIFIC COAST AVIFAUNA No. 7 



June 11 to June 30, 1906 (Univ. Calif. I'ubl. Zool. v, 1908. 72). I took two 

 fresh eggs at Bear Valley, San Bernardino Mountains, June 23, 1907. F. 

 Stephens found a nest containing newly hatched young in the Santa Ana Canon, 

 San Bernardino Mountains, in ]\Iay, 1885 ( Bendire, Life Hist. N. Am. Bds., 1895, 

 219). The altitude in this instance was only about 3000 feet, an exceptionally 

 low elevation for the breeding of this bird. Mr. Stephens has a male of this 

 species that was taken by A. W. Anthony in the San Jacinto Mountains, July 3, 

 1895. This is, so far as I know, our most southern summer record. 



207. (444) Tyrannus tyrannus (Linnaeus). Kingbird. 



One record. Immature male taken by W. B. Judson at Santa Monica, Los 

 Angeles County, August 31, 1895 (Gaylord, Avifauna i, 1895, 29). Now no. 

 10253 collection University of California Museum of Vertebrate Zoology. 



208. (447) Tyrannus verticalis Say. Arkansas Kingbird. 



Common summer resident of the lowlands and mesas, occasional up to 7000 

 feet in the mountains. Arrives in March and leaves in September. Breeds mostly 

 in May and early June. I took an adult male at Bear Valley, 6750 feet in the 

 San Bernardino Mountains, June 24. 1907 (Condor xii, 1910, 44). Extreme 

 nesting dates are : Five eggs, fresh, taken by Antonin Jay at Cerritos, Los Ang- 

 eles County, May 2, 1897, and four eggs, half incubated, taken by W. M. Pierce 

 in San Antonio Caiion, July 8, 1901. 



209. (448) Tyrannus vociferans Swainson. Cassin Kingbird. 



Fairly common resident, locally, in the Lower Sonoran zone. Winters reg- 

 ularly north to Santa Barbara. Breeds mostly in April and early May. H. C. 

 Burt informs me that the Cassin Kingbird is a fairly common breeder in the 

 vicinity of Santa Paula, Ventura County. He took a set of five eggs. May 10, 

 1910. In July, 1893, J. Grinnell found several nests containing young birds in 

 the Simi Valley, Ventura County (Pub. 2, Pasadena Acad. Sci., 1898, 29). In 

 the summer of 1902, G. F. Morcom noted a pair of this species and a pair of 

 Arkansas Kingbirds nesting in the same eucalyptus tree in a yard in Los Ange- 

 les. I took four slightly incubated eggs, with the female bird, near Whittier, Los 

 Angeles County, May 4, 1894. The Cassin Kingbird is recorded by C. S. Sharp 

 as an uncommon breeding bird in the vicinity of Escondido, San Diego County 

 (Condor ix, 1907, 88). According to L. Belding, it is a common summer resi- 

 dent around San Diego (Land Bds. Pac. Dist., 1890, 92). J. G. Cooper noted it 

 breeding in that vicinity as early as March 20 (Land Bds. Cal., 1870, 315). 



210. (454) Myiarchus cinerascens cinerascens (Lawrence). Ash- 

 throated Flycatcher. 



Common summer resident from the oak regions of the mesas up to about 

 6000 feet in the mountain canons ; less plentiful near the coast. Arrives in April 

 and leaves mostly during the first part of September. Breeds most plentifully in 

 late May and e'arly June. H. C. Burt has taken several sets of eggs near Santa 

 Paula, Ventura County, in early June. W. B. Judson took five fresh eggs in the 

 San Gabriel Canon, Los Angeles County. May 16, 1897 (Grinnell, Pub. 2, Pasa- 

 dena Acad. Sci.. 1898, 29). and Antonin Jay took four fresh eggs near Monrovia,
