NORTHERN RAVEN. 



486a. Corvus corax principalis. 25 inches. 



This large crow has the bill proportionally much 

 larger than that of our common crow, and it is par- 

 tially covered with long nasal bristles; the feathers of 

 the throat and neck are also lengthened, narrow and 

 stiff. Eavens are found chiefly along the seacoast, 

 where they feed upon offal, fish, and the young and 

 eggs of various sea birds. They wander about in win- 

 ter, but usually in pairs, and they are supposed to re- 

 main mated for life. 



Notes. Harsh discordant squawks and low chuck- 

 ling noises. 



Range. Eastern North America from Maine north- 

 ward, and south in mountains to Georgia. 

 WHITE-NECKED RAVEN. 

 487. Corvus cryptoleucus. 18^2 inches. 



Similar to the previous species but much smaller 

 and with the bases of the feathers on the back of the 

 head, white. Its habits are like those of the large 

 Raven. It is found in southwestern U. S. and north 



to Nebraska.
