No. 168.) 

 Sp. Charact. — Varied with black and white; forehead spotted; 



crown pale yellow ; bill considerably depressed. 



According to Richardson, this bird exists as a perma- 

 nent resident in all the spruce forests between Lake Supe- 

 rior and the Arctic Sea, and is the most common Wood- 

 pecker north of Great Slave Lake. It resembles P. villo- 

 sus in its habits, seeking its food, however, principally on 

 decaying trees of the Pine tribe, in which it frequently bur- 

 rows holes large enough to bury itself.

inch 1 line ; the tarsus 9^ lines. — Crown pale safFron-yellow, with 



white specs ; the rest of the upper surface and sides of the head 



velvet-black, thickly spotted with white on the forehead, round the 



crown, and on the sides of the throat. A white line from the eye to 



the nape, and another from the nostrils under the eye. Back and 



wings blackish-brown ; inner scapulars and hind part of the back 



barred with white. Tips of most of the quills, and a series of spots 



on their margins, also white. Two middle pairs of tail feathers 



brownish black ; two exterior pairs barred with black at the base ; 



and the intermediate pair largely tipped with white. Chin, throat, 



a line down the middle of the belly, and the under tail-coverts, 



white ; sides of the belly and inner wing-coverts barred with black. 



Bill bluish-grey above, whitish beneath. Legs lead colored. — Female 



smaller, and without the yellow on the crown, the top of the head 



being thickly spotted with white.
