is now known to do so iu Iowa. It is said to occasionally 

 winter in the southern counties, where migrating flocks arrive 

 from the South about, or a little after, the middle of March, 

 and return from the North about the last of October. 



It is a grand bird, weighing often as much as thirty pounds 

 and sometimes nearly forty, with a spread of wings of eight to 

 nearly ten feet — much greater than any other American bird 

 excepting only the Condor and the California Vulture, both of 

 which are considerably inferior in weight. Its eggs, averag- 

 ing about 4.46 by nearly 8.00 inches in size, are so large that 

 one of them is said to be a sufficient meal for a moderate man. 

 Although so large, it is very swift of wing, and Hearne states 

 that in his opinion it is more difficult to shoot when flying than 

 any other bird. 



The name ''Trumpeter" is derived from its ringing note, much 

 more sonorous than that of the common species ( 0. coluia- 

 bianm), and said to resemble a blast upon a French horn.
