Gairdneri occurs in California only in the extreme northwestern corner 

 of the State, the greater portion west of the Sierras being occupied by 

 D. p. turati. (See Fisher, Condor, IV, May, 1902, 68.) 



Xenopicus albolarvatus. White-headed Woodpecker. 



Only three birds of this species were seen in the Siskiyou region. 

 All were shot from sugar pines in the neighborhood of Salt creek. They 

 were obtained on October 10, January 10 and February 19, respectively. 

 These specimens are exactly like the small-billed Sierra Nevadan birds. 

 The known range of the species is thus materially extended, and here 

 seems to be its westernmost station. 



Sphyrapicus varius ruber. Red-breasted Sapsucker. 



This woodpecker was not infrequently seen along Horse and Seiad 

 creeks, mostly in the spruce forest at about 3,200 feet elevation. While 

 not the extreme manifestation of ruber, the four specimens secured, by 

 their large size and dark coloration, easily belong under this head. The 

 white markings of wings and tail are much more restricted than in the 

 Sierra Nevadan daggetti. 



Sphyrapicus thyroideus. Williamson Sapsucker. 



A single individual was found on a ridge above camp on December 19. 

 It was at work in a tall Douglas spruce, and continued tapping hghtly 

 until closely approached. This proved to be a female, and is darker 

 colored than Sierran specimens compared with it. The head is 

 browner, while the deeper yellow belly and extreme length of wing 

 point toward a geographical variation perhaps parallel to S. v. ruber. 



Ceophloeus pileatus abieticola. Northern Kleated Woodpecker. 



The pileated woodpecker is one of the most conspicuous birds of the 

 region. Its loud screech-hke call can be heard for many hundred yards 

 across the canyons. Though often seen it is very wary and difficult of 

 approach. Its favorite resorts seem to be the black oaks, but occa- 

 sional birds are seen to alight in coniferous trees. One specimen had 

 the stomach distended with large black ants, which it was gathering 

 from an oak when shot. As shown by the following measurements (in 

 miUimeters), the four specimens procured belong to the large northern 

 race. There appear to be no significant differences between these and 

 skins from the north Atlantic slope.
