BIRDS OF THE PACIFIC DISTRICT.

preservation but it may be that they become dazzled by 

 the snow if not quite snow-blind. Their nests are usually 

 in rock rose, also called " tar weed " (Chamcebatia, folio- 

 Ion(i), or in " bear bush," " snow bush " (Ceanothus cordu- 

 latus). One I saw was in a hollow stump, but, as usual, 

 was on the ground and was probably made when the 

 snow was several inches deep outside of the stump. The 

 eggs appear to be in most cases from eleven to thirteen. 

 The first broods are out from about June 20 to July 5, 

 according as the season is early or late. 



Cisco. Dr. Cooper (in letter). Cisco, altitude 5,911 

 feet, April 28, on snow. 



Igo. E. L. Ballou. Common resident. March 27, 

 1884, the species was mated here. June 1, sitting. 



Henshaw, 1879. It is only at rare intervals that it 

 appears to cross the mountains and appear along the 

 eastern slope. About Carson, at Eagle and Honey 

 Lakes, California, and at the Dalles on the Columbia, 

 their presence was detected and is to be accounted for 

 through the natural dispersion of the species. At several 

 localities near Camp Bidwell, Cal., the several covies are 

 the descendants brought from the Pacific Slope and let 

 loose to shift for themselves. They are nowhere in this 

 region very numerous.

 Introduced from California. 



[Perhaps those seen at the Dalles by Mr. Henshaw 

 belonged under 0. pictus. Those I found in Butte Co., 

 lat. 40 10', altitude about 5,000 feet, were identical with 

 those found farther south in the Sierra Nevada. I be- 

 lieve San Pedro Mountain, Lower California, is the most 

 southern known range of the genus Oreortyx. I am 

 positive that it does not inhabit Lower California south 

 of La Paz, and doubt if it ever did. San Pedro Mount-
