394d. Nelson’s Downy Woodpecker. 
Dryobates pubescens nelsont OBERHOLSER. 1895. 
We place here without remark all references to the downy 
woodpecker of the northern parts of Canada and Alaska. We 
have no specimens. 
This species is a constant inhabitant of the Northwest Terri- 
tories up to Lat. 58°. It seeks its food principally on the maple, 
elm and ash, and north of Lat. 54°, where these trees do not 
grow, on the aspen and birch. (ichardson.) North to Fort 
Laird, Lat.61°; not rare. (Ross.) A few specimens were observed 
on the Athabasca River, Alta. Rare between Methye Lake and 
Isle a la Crosse. (J. M. Macoun.) Throughout Alaska where 
woodland ora growth of bushes and small trees occurs the present 
bird is certain to be found, and is a resident, winter and summer. 
(Vlson.) This species ranges throughout the wooded districts of 
Alaska. Along the Yukon River it is very common. (Zurner.)
