examples of sifkensis taken in the early fall, in freshly acquired 

 winter plumage, but even in these the color is not quite the same, 

 and taking comparable specimens, there is no difficulty in dis- 

 tinguishing the two forms (judging from the material at hand), 

 by this one character alone. 



The white-spotted wing coverts of the Sitka woodpecker have 

 been remarked upon by Jenkins (1906, p. 168) and Grinnell (1909, 

 p. 216) as being peculiar to this northern form, as distinguished 

 from typical harrisi of the Puget Sound region, but I do not find 

 that this is the case, for in the series at hand from Vancouver 

 Island (eighteen specimens) these spots are almost invariably 

 present in some degree, nearly to the extent shown in the Sitkan 

 birds. This is a character that seems to vary independently of 

 the otherwise general darkening of the species in the humid 

 northwest. Thus the Alaskan subspecies is a relatively paler- 

 colored race with fairly conspicuously white-spotted wing coverts, 

 the Puget Sound harrisi (as represented by Vancouver Island 

 specimens) is very much darker colored, with the wing coverts 

 somewhat less conspicuously marked, while the white-bellied 

 form found in California has the wing coverts uniformly black.
