1903.] NATURAL SCIENCES OF PHILADELPHIA. 9 



Melanerpes torquatus. Lewis Woodpecker. 



The first bird noticed on crossing the Klamath and entering Horse 

 creek canyon was the Lewis woodpecker. The species was then, Sep- 

 tember 6, abundant in oaks bordering the meadows near the mouth of 

 the creek. On September 13, two specimens were shot from a spruce 

 near Grater's farmhouse. There were a number of others about at the 

 time, but at the report of the gun they made off down the canyon, and 

 nothing was afterward seen of the species anywhere in the region. It 

 probably occurs only as a migrant. 



Colaptes cafer saturatior. Northwestern Flicker. 



Flickers were seen in the yellow pine forests on the ridge west of 

 camp all through the fall and early part of winter, but they were so 

 excessively shy that none were secured until January 20. They were 

 always abundant near the mouth of Seiad creek, in some open meadows 

 lined with oaks, and alders overgrown with wild grapevines. As com- 

 pared with specimens from the vicinity of Monterey, the type locality 

 of coUaris, the three skins from the Siskiyou country show somewhat 

 greater dimensions and also darker colors. This is especially noticeable 

 on the back, which is a decidedly richer brown, the ground color being 

 deep Prout brown. 



Sayornis saya. Say Phoebe. 



On September 16 a Say phcebe was shot from its perch on the barn at 

 Grater's place. This was the only bird noted, and so is probably repre- 

 sented in the region only as a migrant. 



Cyanocitta stelleri carbonacea. Coast Jay. 



This was the only jay detected in the Siskiyou Mountains, and was 

 by no means as conspicuous as jays often make themselves. Only 

 occasionally was one heard scolding in some cluster of spruces, or dis- 

 covered hopping quietly from limb to limb in a black oak. Eight skins 

 were obtained during the winter, and all proved to be quite typical of 

 the humid coast race carbonacea (see Fisher, Condor, lY, March, 1902, 

 41). But a female specimen taken at Walker Post Office, Siskiyou 

 county, March 11, 1902, is very different, approximating C. s. frontalis, 

 though not as pale as the average of southern California birds. Walker 

 is only about twenty miles due east of Seiad Valley, and about forty- 

 five miles northwest of ]\It. Shasta. If this specimen represents the 

 resident race of its locality, it furnishes a very interesting example of 

 the possible close invasion of two races toward each other from their 

 original separate centres of differentiation (until the area of intergrada- 

 tion may ultimately disappear).
