BIRDS OF THE PACIFIC DISTRICT. 263 



Beaverton, Oregon. A. W. Anthony. Common sum- 

 mer resident; first seen February 29, 1884. March 15 

 abundant. 



295. Sialia arctica (Swains.) MOUNTAIN BLUEBIRD. 



San Diego. L. B. Common until March 15, 1884, 

 when it disappeared, but a large flock returned March 

 29 during a cold rain-storm and stayed two days. April

 range of 8. mexicana, though I found a few pairs of 

 both species breeding at an altitude of 5,800 feet in 

 Butte County, an unusual occurrence. 



Poway. F. E. Blaisdell. It arrived November 10,

 they had been in the habit of visiting this locality. 

 January 3, 1885, a flock seen; the only ones seen this 

 winter. 



Alamedaand Contra Costa counties. W. E. Bryant. 

 Tolerably common winter visitant. 



Marysville. W. F. Peacock. February 13, 1884, last 

 seen. 



British Columbia. John Fannin. Rare migrants; 

 found only east of Cascade Mountains. 



Ridgway. This is the characteristic bluebird of the 

 interior, and it is most numerous where other species 

 are rarest. In June it was common at Virginia City 

 where it nested in the manner of the eastern species in 

 suitable places about buildings in the town. It was also
