1912 BIRDS OF SOUTHERN CALIFORNIA 13 



17. (36) Stercorarius pomarinus (Temminck) . Pomarine Jaeger. 

 Jaegers are frequently seen along our coast, but, as few specimens have been 



taken, it is hardly possible to estimate the comparative abundance of this species 

 and the next. According to the last A.O.U. Check-List, the Pomarine Jaeger 

 is a common fall migrant on the coast of California, wintering south to the 

 Galapagos Islands- It occurs at Point Pinos, Monterey County, every month 

 in the year, but is really common only during the passage southward in August, 

 September and October (Beck, Proc. Cal. Acad. Sci., ser. 4, vol. in, 1910, 61). 

 We may safely conclude from the above that the species is rather common on 

 the ocean in the fall, and may occasionally be found at other times of the year. 



18. (37) Stercorarius parasiticus (Linnaeus). Parasitic Jaeger. 

 Fairly common fall and winter visitant along the coast. According to R. H. 



Beck, most numerous on the coast of Monterey County in August and September 

 (Proc. Cal. Acad. Sci., ser. 4, vol. in, 1910, 61). Noted by H- W. Henshaw 

 as common in December, 1884, from Santa Barbara north (Auk n, 1885, 232). 

 Recorded by B. W. Evermann as frequently seen in winter along the coast 

 above Ventura (Auk in, 1886, 88). H. S. Swarth took a female at Santa 

 Monica, Los Angeles County, September 29, 1895 ( Grinnell, Pub. 2, Pasadena 

 Acad. Sci., 1898, 6). I took a male at Hyperion, Los Angeles County, December 

 15, 1911; and on December 18, following, I took two more specimens and 

 Antonin Jay secured one, in the same locality. 



19. (38) Stercorarius longicaudus Vieillot. Long-tailed Jaeger. 



One record, that of a young male taken by H. W. Marsden at Pacific 

 Beach, San Diego County, September 19, 1904 ( Bishop, Condor vii, 1905, 

 141). Now no. 11682, collection L. B. Bishop. 



20. (40a) Rissa tridactyla pollicaris Ridgway. Pacific Kittiwake. 



Regular winter visitant in small numbers, south to Lower California. A fe- 

 male in first winter plumage was sent to J. Grinnell from Playa del Rey, Los An- 

 geles County, where it was found dead on the beach, January 9, 1906 (Condor 

 viii, 1906, 57). Antonin Jay has an immature male found dead on the beach in 

 the same locality, December 30, 1911. C. B. Linton took a female at Alamitos 

 Bay, Los Angeles County, April 14. 1907 (Condor ix, 1907. 199). A. W. 

 Anthony noted the Kittiwake as of regular, though not common, occurrence, 

 off San Diego and about the Coronados Islands (Auk xv, 1898, 267). He 

 took a specimen near San Diego February 26, 1895 (Auk xn, 1895, 177). 



21. (44) Larus glaucescens Naumann. Geaucous-winged Gull. 



Regular winter visitant in small numbers, south at least to San Diego. Re- 

 corded by B. W. Evermann as a winter visitant at Ventura, though not common 

 (Auk, in, 1886, 88). J. Grinnell noted it at Catalina Island in December, 1897, 

 and W. B. Judson took an immature bird at Redondo, Los Angeles County, in 

 winter (Pub. 2, Pasadena Acad. Sci., 1898, 6). Several immatures were noted 

 by G. F. Breninger at San Clemente Island in February, 1903 (Auk xxi, 1904, 

 219). I have an immature female taken by Antonin Jay at Hyperion, Los 

 Angeles County, July 4, 1910, and I saw an adult bird in the same locality
