Oregon ruffed grouse were preserved, and the species may be considered 

 fairly common through the winter in this region. This bird has been 

 found previously inCaUfornia only in the redwood forests in the vicinity 

 of Humboldt Bay, so that the present record extends its known range 

 considerably to the eastward. Douglas, in the original description of 

 his "Tetrao Sabini," gives its range as "from Cape Mendocino" north, 

 etc. But recent records, up to the present, indicate ordinarily a dense 

 forest habitat. 



Buteo borealis calurus. Western Red-tailed Hawk. 



An immature male red-tail was shbt on October 11 on the very sum- 

 mit of the Siskiyou, where the Oregon trail crosses. 



Falco sparverius phalsena. Western Sparrow Hawk. 



One was observed on March 2 between Oak Bar and Walker on the 

 Klamath. 

 Ceryle alcyou. Belted Kingfisher. 



A single individual was observed flying up Horse creek on January 1 6. 



Dryobates villosus harrisi. Harris Woodpecker. 



This bird is very common in the groves of black oak which are 

 located here and there on the lower parts of the Siskiyou range. It is 

 also found in the coniferous forests, though in smaller numbers. From 

 October 24 to February 15 fifteen specimens were taken. These are 

 variously intermediate in coloration between hyloscopus and harrisi, 

 but average nearest the latter. Five of the birds have all the white 

 areas strongly suffused with smoke-gray or brown, nearly but not quite 

 as deeply as in specimens from western Oregon and Washington. Four 

 have all the areas practically pure white, while the other six are fairly 

 intermediate between these two types. The whole fifteen present an 

 uninterrupted series, from the whitest to the dingiest. The usual size 

 of all the specimens, however, is that of harrisi; that is, decidedly 

 larger than the white-breasted hyloscopus, which occupies nearly the 

 whole of California in favorable localities outside of the extreme north- 

 ern humid coast belt. 



Dryobates pubescens gairdneri. Gairdner Woodpecker. 



The Gairdner woodpecker is usually to be found in company with 

 the flocks of mountain chickadees which frequent the black oak groves 

 all winter. The oaks are their favorite working places, but they are 

 also to be seen among the pines and spruces. The six specimens 

 brought home are all quite near gairdneri. The smokiness of the lower 

 surface is not so intense as in skins from western Oregon, but the size, 

 especially of the feet, is decidedly that of the northwest coast form.
