20 PACIFIC COAST AVIFAUNA No. 7 



until later in the season. L. II. Miller has an adult female taken near Santa Bar- 

 bara Island, April 10, 1904; in June, 1911, I found the species plentiful in the 

 channel between Santa Barbara and San Nicolas islands. Although at this time 

 I made careful search over all of the former island and part of the latter, I was 

 unable to find any evidence of the species breeding". 



50. (108.1) Oceanodroma socorroensis C. II. Townsend. Socorro 

 Petrel. 



Breeds on the islands ofif the coast of Lower California from Los Coronados 

 south. Straggles northward at least to San Diego, where A. W. Anthony found 

 it to be fairly common during April and May, 1895, at which time he took a small 

 series of specimens (Auk xii, 1895, 387). Godman considers this form identical 

 with Oceanodroma monorhis (Swinhoe), a race found on the coast of China and 

 Japan (Mon. Petrels, 1907, Z2-?>c>). 



51. (120c) Phalacrocorax auritus albociliatus Ridg\vay. Farallon 

 Cormorant. 



Common resident along the coast. Breeds on the Santa Barbara Islands in 

 May and June. J. Grinnell and H. A. Gaylord took two sets of fresh eggs on 

 Santa Barbara Island, May 15, 1897. At this date most of the birds were nest 

 building (Pub. 1, Pasadena Acad. Sci., 1897, 25). June 15, 1910, I found the 

 species breeding commonly on San Miguel Island. Nest contents varied from 

 fresh eggs to half-grown young (Condor xii, 1910, 173). In some instances, 

 probably where previous sets have been destroyed by the gulls, eggs may be found 

 as late as August. 



52. (122) Phalacrocorax penicillatus (Brandt). Brandt Cormorant. 

 Common resident along the coast. Breeds on the Santa Barbara Islands in 



April, May and June. C. B. Linton noted incomplete sets on San Nicolas Island, 

 April 3, 1910, and I took four sets of fresh eggs on Catalina Island, April 11. 

 1904. J. Grinnell and H. A. Gaylord took thirty sets of eggs on Santa Barbara 

 Island, May 15, 1897. They were in all stages of incubation, and several nests 

 contained newly hatched young (Pub. 1, Pasadena Acad. Sci., 1897, 25). I found 

 several large colonies nesting on San Miguel Island in June, 1910. On the 15th 

 of the month, nests contained fresh and incubated eggs and young of various 

 ages (Condor xii, 1910, 173). 



53. (123bj Phalacrocorax pelagicus resplendens Audubon. Baird 

 Cormorant. 



Common resident on the Santa Barbara Islands, but less plentiful than the 

 two preceding species. Occasional along the mainland shores in winter. Breeds 

 in May and June. J. Grinnell and H. A. Gaylord noted this species breeding on 

 Santa Barbara Island, May 15, 1897 (Pub. 1, Pasadena Acad. Sci., 1897, 26), 

 and I found them nesting commonly on Anacapa and San Miguel islands in June, 

 1910. Fresh eggs were taken on the latter island as late as June 19 (Condcn- xii, 

 1910, 170, 174). 



54. (125) Pelecanus erythrorhynchos Gmelin. White Pelican. 

 Regular visitant to the marsh lands in fall, winter and spring. Arrives in
