BIRDS OF THE PACIFIC DISTRICT. 81 



rather numerous about some rocky bluffs close to the 

 sea shore, March 22. I saw none at Fort Mojave until 

 May. On the 7th of June, near the head of the Mojave 

 River, I found a few about some lofty granite cliffs. 



San Diego, December 15, 1S83, a few near the bay. 

 El Cajon, twelve miles east of San Diego, January 16, 

 1884, a hundred or more flying about a pond, several 

 shot; all very fat, proving that insect food was ample, 

 in winter, here, for their support. I heard of these after- 

 ward in January, but swollen unbridged streams and 

 very bad roads restricted my observations in February, 

 March and April to the immediate vicinity of San Diego, 

 and consequently I did not again look for them, and did 

 not again see the species at San Diego. — L. B. 



San Bernardino. F. Stephens. — Tolerably common 

 summer resident of the foothills; rare winter visitant to 

 the valley and foothills. Agua Caliente, March 2o-28, 

 1884, common in neighboring canons. In 1886, seen 

 from March 24 to April 15 (day of leaving). 



Baird, Brewer and Eidgway. — Dr. Cooper saw many 

 of this species in the canon of Santa Ana, May 20. He 

 also saw them near San Buenaventura, August 25, when 

 they came down the valley from the sandstone cliffs ten 

 miles distant. They afterwards hunted insects daily 

 near the coast, flying high during the calm morning, but 

 when there were sea breezes flying low and against it. 

 After a month they disappeared and none were seen un- 

 til December 14, when they were again seen until the 

 20th. None were seen during the rains or until Febru- 

 ary 26, when they reappeared. After April 5 they re- 

 tired to the mountains. 



Port Harford. L. B.— March 29, 1881, two or three 

 dozen. Summit, Central Pacific Railroad, July 2, 1885 

 from four to six dozen, also seen in August. Breeds in 

 lava cliffs of Calaveras County.
