This species is the “Noble Peregrine” of falconry. It would be 
difficult to imagine a bird more highly endowed with qualities which 
make the ideal bird of prey. Its strength of wing and talon is equaled 
by its courage. Few birds fly more swiftly than the Duck Hawk. Even 
Teal—those winged bullets—can not escape it. No bird is more daring. 
I have had Duck Hawks dart down to rob me of wounded Snipe lying 
almost at my feet, nor did my ineffective shots prevent them from 
returning. Duck Hawks are generally found near water, where they 
prey largely on water birds. 
“Of 20 stomachs examined, 7 contained poultry or game birds; 9, 
other birds; 1, mice; 2, insects; and 4 were empty” (Fisher). 
The Perecrine Fatcon, or Orp Wortp Duck Hawk (366. Falco
