Corvus amerioanus. 
1892. Mass . 
Oct. 12. Concord .- about for several minutes finally returning to the Imnena* 
woods and meadow and separating into smaller flocks. I counted flock 
them roughly( or father tried to) and made out their number to be of 
upwards of 200 birds, an unusually flairfee flock. The movement Crows , 
just mentioned was doubtless a "false start" for about an hour 
later the whole body mounted to a height of at least a thousand 
feet and went off due south. Their order of flight was not 
loose and straggling as is uaually the case during migrationjbut 
in a compact flock each individual of which had no more horizon- 
tal space than was required for the free use of his wings. 
There was a good deal of cawing in fact it was incessant-but the 
combined clamor was less than one would expect from so many bird 
It came to mv ears with perfect distinctness when the flock had 
passed .bevond my vision although no obstacles intervened and the 
air was free from haze. When the birds were rising and circling 
over me I heard the cr-r-r-r and cluck-cluck-cluck-cluck calls 
frequently (this rendering was noted on the spot). 
I do not remember to have seen Crows migrate in this way 
before. They usually fly in windy weather low down, and in 
loose, scattered flocks. The size of this flock was also remark- 
able.
