 Popular synonym : Common Crow. 



The American Crow is an abundant resident. In his hst of 

 Cook County birds, Mr. Robert Kennicott says that the Crow 

 was at that time (1853-1854) "Common throughout the state." 

 Mr. E. W. Nelson, on the other hand, while Hsting the Crow as 

 resident, says: "This is far from an abundant species in North- 

 ern IlHnois, at any season or locaHty. A small number breed 

 in the low pines on the sand hills along the Lake shore, and in 

 winter unite in small flocks and move from place to place." 



The range of the Crow includes the whole of North America 

 from the Fur Countries on the north southward to the southern 

 border of the United States. It is rare or local in the interior 

 western districts.
