mountains, snow often covering tlie ground to the depth of 

 two feet. Nine inches fell during one night. 



I am under obligations to Dr. J. G. Cooper and Mr. Kob- 

 ert Ridgway for identifying several of the species included 

 in these lists. Specimens were taken of all excepting Golden 

 Eagle, Turkey Buzzard, Crow, and Sandhill Crane. 



Arriving on the mountains in January, bird life was met 

 with in profusion, scattered among the trees and bushes, no 

 storms having yet occurred to drive them down to the val- 

 leys or confine them to sheltered flats along the creeks. 

 After the first hard rain storm they commenced moving 

 lower down, and the first fall of snow, towards the latter 

 part of January, sent them hurrying to the warmer valleys. 



The species taken or seen on the mountains were as fol- 

 lows: 



1. Grus mexicana. 



Sandhill Cbane. — A large flock was seen flying north- 

 ward March 16th, and another on March 20th. 



2. Oreortyx pictus plumiferus. 



Plumed Paetridge. — A bevy of forty or more was seen in 

 January. They were not as common as the Valley Par- 

 tridge. 



3. Callipepla californica vallicola. 



Valley Partridge. — Abundant. This species withstands 

 the cold and snow far better than its larger relative. The 

 Plumed Partridge became scarce after the first heavy fall of 

 snow, having gone to a lower altitude to winter. 



4. Gathartes aura. 



Turkey Vulture, — Only noticed on one occasion, when 

 eight or nine were seen circling above the main ridge (Feb- 

 ruary 22d). 



5. Accipiter velox. 



Sharp-shinned Hawk. — One seen February 22d.
