Birds of Dead Biv'er Begio-n, Me. F. H. 0. 
72. Picoides arctieus , (Black-backed Tliree-toed 
Woodpecker). The most common Woodpecker 
of the interior forest, and were to be found in all 
sections of the counties. Erratic in movements, 
being seen at times in great numbers and again 
disappearing entirely for a number of days. Their 
tenacious hold upon the rough bark of the spruce 
trees would be retained after being shot. A nest 
excavated in a living spruce, on Boundary Moun- 
tains contained young on June 9, ’79. Another 
nest was in a dead stub, near Moose River, and 
contained four eggs, being found by Dr. Northrup 
May 28, 1885. Other nests found by myself in 
other portion of the State did not differ.
