Abies concolor lowiana. 



A fir probably referable to this form is found in the lower portion of 

 Canadian and higher Transition, where it occurs in company with the 

 Douglas spruce. In the canyon of Horse creek it was seen down to an 

 altitude of 3,100 feet. 



Pinus monticola. Mountain Pine. 



This tree is frequent in the Canadian zone, to which it seems 

 restricted. 



Hudson: AN Zone. 



Tsuga mertensiana. Black Alpine Hemlock. 



Hemlocks grow in abundance near the head of the east fork of Horse 

 creek and elsewhere along the range in cool places. During a tramp 

 along the crest this tree was seen repeatedly. 



Notes on the Birds of the Region. 



Ardea herodias herodias. Great Blue Heron. 



On January 25 a great blue heron was seen on Seiad creek, about four 

 miles above the mouth. Again, on March 2, two herons were observed 

 on the Klamath river, between Oak Bar and Walker Post Office. 



Oreortyx pictus plumiferus. Mountain Partricige. 



On September 12 a small boy brought in two cjuail which had been 

 shot near the house on Grater's Ranch. Subsequently the species was 

 detected only once : a flock of six or eight were seen in Seaid Valley on 

 December 20. The two September birds were preserved, and in spite 

 of extremely abraded plumage, are plainly referable to plumiferus, and 

 not pictus, as one might expect. One of the specimens is adult and 

 shows a few new feathers appearing on the scapulars, breast and sides, 

 but there is no evidence of approach toward the brown-necked humid 

 coast form. This is an interesting example of the westward extension 

 of a Sierra Nevadan form. 



Bonasa umbellus sabinei, Oroyon Ruffed Grouse. 



The people of the Siskiyou state that this l^ird is invariably seen on 

 the ground or on fallen logs. The observations of the past winter go to 

 confirm this, for all the grouse seen were upon the ground or flying near 

 it, and in all cases were in groves of small Douglas spruce, such as 

 grow near or in the canyon bottoms. There is another grouse known to 

 the inhabitants of this region. This l^ird is said to l)e found mainly in 

 trees and is doubtless the sooty grouse (Dendragapus obscurus fuligi- 

 nosus). In the latter part of Februar}- and early in IMarch, the drum- 

 ming of what was thought to be this latter species was heard, but not 

 even a glimpse was obtained of the performer. Foiu' specimens of the
