THE MARSH HAWK 



63 



The preponderance of meadow mice found in the stomachs of 124 

 Marsh Hawks obtained in various parts of the United States, as re- 

 corded by Dr. Fisher, speaks for the careful preservation of this 

 bird of prey. 



Because they frequent the marshes where gunners pursue wild- 

 fowl, they are in the greater danger, and are more often shot care- 

 lessly as well as intentionally by hunters who little appreciate the 

 economic value of these birds. 



R. M. Anderson records that Mr. C. F. Henning of Boone found 

 three adult and eight young field mice in the viscera of a Marsh Hawk 

 taken October 20, 1890.
