92 PACIFIC COAST AVIFAUNA No. 7 



Ana River bottom near San J^ernardino (Auk xiii, 1896, 265). L. H. Miller 

 saw a male at Riverside, December 2, 1911. H. S. Swarth has noted Phain- 

 opeplas in Westlake Park, Los Angeles, on several occasions in mid-winter and 

 saw one bird near Los Angeles, March 12, 1899. J. S. Appleton has noted the 

 species on several occasions during the winter months in the Simi Valley, \ en- 

 tura County. 1 saw a bird in this locality, ' P'ebruary 25, 1912, and the fol- 

 lowing day I took a male in the same vicinity. Its testes were much enlarged 

 and it would undoubtedly have bred within a short time. Extreme nesting 

 dates for Los Angeles County are : Two slightly incubated eggs taken by 

 H. A. Gaylord near Pasadena, May 4, 1897, and two fresh eggs taken by Mr. 

 Gaylord in the saiue locality, July 28, 1894 ( Grinnell, Pub. 2, Pasadena Acad. 

 Sci., 1898, 43). J. S. Appleton took a set of eggs in the Simi Valley, Ventura 

 County, in late March. 



310. (622b) Lanius ludovicianus gambeli Ridgway. California Shrike. 

 Abundant resident from the coast to the base of the mountains. Breeds 



mostly from late March to the latter part of May. Extreme nesting dates are : 

 I'lve eggs, fresh, taken by H. j. Lelande near Pasadena, February 14, 1897 

 (Grinnell, Pub. 2, Pasadena Acad. Sci., 1898, 43), and four eggs, incubation 

 advanced, taken by W. M. Pierce near Claremont, Los Angeles Countv, July 

 5, 1903. 



The shrikes that occur along the southeastern border of the coastal slope 

 of southern California are variously intermediate between this form and L. I. 

 cxcuhitoridcs, some speciniens approaching the latter very closely. 



311. (622c) Lanius ludovicianus anthonyi Mearns. Island Shrikk. 

 This insular form, described from specimens taken by R. H. Beck on Santa 



Cruz Island in May, 1897 (Auk xv, 1898, 261), is a fairly common resident on 

 Santa Cruz Island where it is found mostly around the ranch houses and culti- 

 vated lands. It is resident on San Clemente Island but is less plentiful than on 

 Santa Cruz. It is found on Santa Rosa Island but 1 have no information as to its 

 abundance. One bird was seen there by H. J. Lelande and O. W. Howard, June 

 8, 1910. H. Robertson and V. W. Owen saw a pair of these birds and found a 

 nest containing young, on Anacapa Island, June 4, 1899, but when I visited this 

 island in June, 1910, none were seen. It is resident on Catalina Island in small 

 numbers. 



R. H. Beck took four .sets of eggs on Santa Cruz Island, May 6 to 11, 1897 

 (Mearns, Auk xv. 1898, 264), and J. Mailliard took two sets of eggs and found 

 several nests in course of con.struction on the same island in late April, 1898 

 (Bull. Cooper Orn. Club, i, 1899, 41 ). C. B. Linton noted the following nests on 

 San Clemente Island in March, 1907. One downy young and two infertile eggs, 

 March 8 ; five eggs, two-thirds incubated, March 7 ; and five eggs, fresh, March 

 19 (Condor x, 1908, 85). J. Grinnell took five slightly incubated eggs on the 

 same island, April 2, 1897 (Pub. 1, Pasadena Acad. Sci., 1897, 19). R. M. Perez 

 took five fresh eggs on Catalina Island, April 15, 1911.
