 Nu Ni6 Adult with Young on Nest on Ground. (1900) Chapman 



This is a good example of protective coloration. 



Nu Ni7 Adult Asleep on Log. Weymouth, Nova Scotia 



C. Will Beebe 



During the day the nighthawk in wooded regions perches upon 

 a log or limb ; in the open country it roosts upon the ground. It 

 can not perch upon small branches because its feet are too small 

 and weak. It rests lengthwise on larger branches for better sup- 

 port and in so doing simulates a knot or bump. 



Nuthatch, White-breasted (Sitta carolinensis carolinensis) 



Among the most conspicuous of winter birds is this very inter- 

 esting one that may be recognized by its peculiar habit of going 

 down a tree head foremost. It has a harsh call, hardly in keep- 

 ing with its colors. Its food consists of insects that it discovers 

 in the crevices of bark and various other places. It is also fond 

 of oily seeds such as those of the sunflower. 5.5-6 



Nu NuW Adult on Side of Stump, Characteristic Position. (April 

 14, 191S) Allen 



This bird was attracted by suet forced into a hole in the stump. 

 Note th« long upcurved bill, short tail and perching-bird type 

 of foot. 



Nu NuW2 Adult Female with Food at Nest in Tree Trunk. Ithaca. 

 (June 2, 1915) Allen 



Gathers its food chiefly from tree trunks and so does not have 

 far to go from the nest to find it. Usually selects for its nest a 

 cavity in a tree entered through a knot hole.
