frequenting localities of all descriptions, now running over some 

 cultivated field, then gathering upon some swampy, muddy shore, 

 or along the road. 



The crow builds rather early. The nest is a somewhat course 

 and rough looking structure, situated usually at a considerable 

 distance from the ground, on a tree, very often of the pine species. 

 A nest with three nestlings almost ready to fly was obtained by 

 the writer early in May. 



A well known fact is their gathering in immense numbers at 

 certain roosting places, in tracts of woods, from whence they start 

 regularly in the morning, and return in the evening, always

When assembled together their screaming sometimes becomes
