110 PACIFIC COAST AVIFAUNA No. 7 



December (xA.uk in, 1886, 186). I have found it plentiful during some winters in the 

 vicinity of Los Angeles, and during other winters have failed to see it. Accord- 

 ing to J. G. Cooper, during the severe winter of 1861-2, these birds came 

 down in large numbers to the vicinity of San Diego and remained until the end 

 of February, when all suddenly disappeared (Land Bds. Cal., 1870, 29). During 

 the spring of 1884, L. Belding found it common at San Diego until March 15, 

 when it disappeared. A large flock returned March 29, during a cold rain storm, 

 and stayed two days. A female taken April 4, was the last seen (Land. Bds. Pac. 

 Dist., 1890, 263). During June, 1907, I found the Mountain Bluebird fairly 

 common at Bear Valley, 6750 feet altitude in the San Bernardino Mountains. 

 Several nests were examined, all of which contained young ( Condor xn, 

 1910,44). 



HYPOTHETICAL LIST 



1. (5) Colymbus dominicus brachypterus Chapman. Mexican Grebe. 

 Often quoted from W. Gambel as occurring in "Upper California." No 



definite record. 



2. (83) Thalassogeron culminatus (Gould). Yellow-nosed Albatross. 

 An inhabitant of southern oceans. Said to occur casually north to the coast 



of Oregon. No California specimens known. 



3. (84) Phoebetria palpebrata (J. R. Forster). Sooty Albatross. 



A southern species which has frequently been stated to occur "north to the 

 coast of Oregon," without, however, a great deal of definite data to substantiate 

 its occurrence so far north. A specimen recorded by C. P. Streator as having 

 been taken near Santa Barbara (Orn. & Ool. xi, 1886, 90). Its present where- 

 abouts unknown. 



4. (87) Priocella glacialoides (A. Smith). Slender-billed Fulmar. 

 A bird of southern oceans. Said to occur north along the Pacific coast to 



Oregon. Supposed skeleton found by J. G. Cooper on Catalina Island in 1863 

 (Baird, Brewer & Ridg., Water Bds. N. Am. n, 1884. 374). Also recorded by 

 Dr. Cooper as found dead on the beach near Ventura (Auk iv, 1887, 87). 



5. (181) Olor buccinator (Richardson). Trumpeter Swax. 



This bird, now believed to be nearly if not quite, extinct, is frequently stated 

 to have occurred in winter in Los Angeles County. So far as I have been able 

 to ascertain, these statements all originated from specimens obtained by A. M. 

 Shields, which specimens, I am informed by Mr. Shields, were destroyed in the 

 San Francisco fire. As it has since been found that the Whistling Swan (Olor 

 columbianus) , is a fairly common winter visitant to Los Angeles County, and as 

 buccinator has not been further noted in this locality, I am inclined to believe that 

 Mr. Shields' specimens were wrongly identified, and should be referred to 

 columbianus. 



6. (183) Ajaia ajaja (Linnaeus). Roseate Spoonbill. 



Recorded by W. Gambel as occurring on the coast of California in 1849
