Ued-shouldered Hawk-. 220 stomachs were examined: 3 contained poultry; 

 1-^, otlier birds; 142, mice and other mammals; 59, reptiles, etc.; 109, insects; 7, 

 crawfish; 2, otial; 3, lisli; and 14 were empty. 



Broad-winged Hawl\ 65 stomachs were examined: 2 contained small birds; 

 28, mice and other mammals; 21, reptiles, etc.; 32, insects, etc.; 4, crawfish; and 

 7 were empty. 



Rough-legged J la irk. 49 stomachs examined: 45 contained mice and other 

 mammals; 1, lizards; 1, insects; and 4 were empty. 



Sparrow HawJi. 320 stomachs examined: 1 contained a quail; 53, other birds; 

 101, mice and other mammals; 11, reptiles, etc.; 244, insects, etc.; and two were 

 empty. 



Marsh IlawJc. 124 stomachs were examined : 7 contained poultry or game 

 birds; 34, other birds; 79, mice and other mammals; 9, reptiles, etc.; 14, insects; 

 and 8 were empty. 



Thus it can be seen that of the 49 stomachs of the Kough-legged Hawk exam- 

 ined by Dr. Fisher, and the 32 examined by me, in 1895, not one contained a trace 

 of any domestic fowl and nearly every one contained mice. Yet many people 

 persist in calling this bird the " Big Hen Hawk " and in treating it as an enemy, 

 when both by law and public opinion it should be protected by every possible means. 

 The statement as to all the other species that I have referred to as beneficial is 

 equally corroborated by my own experience, and shows how well entitled these birds 

 are lo consideration at our hands instead of the persecution they usually meet.
