27. Grus americana. Whooping Crane. — Several flocks of large

 rolling call; one of these flocks contained 57. On the night of Sept. 

 21 there was a heavy migration of these birds, their call being heard at all 

 hours of the night. Positive identification was impossible, but as the 

 birds were very large, and were migrating from the north, it seems reason- 

 ably certain that they were Whooping Cranes.
