Corvus amer icanus . 
Concord, Mass. 
1393^ Yesterday I saw a flock of Crows, which I estimated to 
Aus.lt • contain about thirty birds, at Ball's Ilill. They were there 
again to-day and I counted them accurately; there were thirty- 
eight. They were feeding on the recently cut meadow most of 
the time. When flying they kept well bunched. They acted on 
the whole like migrants from the north.
