season, a behavior in keeping with its independent, hardy nature and 

 one for which its habits of feeding in small brush would well adapt it. 

 The often associated Yukon chickadee may also nest in the timber and 

 move north in winter. 



I am inclined to think of the downy woodpecker as a visitor after 

 nesting season. 



Along the Yukon and on its Delta Turner (1886) reported these 

 woodpeckers as common and present in winter. 



Picoides arcticus (Swainson) 



Charles Sheldon of Kobuk informed me that both a ladder-back and 

 a black-backed woodpecker with yellow head were well known in the 

 spruce timber along the Kobuk. To demonstrate his point, he later 

 sent me the skin of a male of arcticits, obtained April 22, 1954, weigh- 

 ing 71 grams. Grinnell (1900) had found fasciatus nesting on the 

 Kobuk at Hunt River. It is apparent that both these forms of Picoides 

 occur in arctic Alaska near the limit of spruce timber, but it is unlikely 

 that either would pass north of the forests. 



Picoides tridactylus fasciatus Baird 



Three examples of northern 3-toed woodpeckers have been brought 

 to me from the spruce forest in the vicinity of Hunt Fork. These 

 are a male, January 16, 1948; a female, December 22, 1947, and 

 another male November 27, 1947. The skins of the two former were 

 sent to George Sutton and identified by him. The third, obtained in 

 the spring of 1948, was too badly decomposed for preservation. 



This is the woodpecker which the Nunamiut know as ToyuJcpuh, but 

 as it means only "larger Toyuk^'' the name is hardly specific. There is 

 no indication that these woodpeckers ever abandon the wooded areas 

 nor does it seem likely that their feeding habits among the large spruce 

 trees would enable them to do so. But they do dwell in the most 

 northern timber. They are not included in the avifauna of the Valley.
