FALCO PEREGRINUS I DUCK HAWK. 113 



" Although the Duck Hawk has been long known to 

 breed at the localities in Massachusetts mentioned above 

 [Mounts Tom and Holyoke], those conversant with the 

 fact were not aware that any special interest was attached 

 to it, or that its eggs and breeding-habits were very little 

 known to ornithologists ; and so, until very recently, no

 later he made another visit, and, creeping carefully to the 

 summit of the cliff, at a point near the eyrie already 

 spoken of, he saw the female, on looking over the cliff, 

 sitting on the nest, and but five or six yards distant. 

 She eyed him fiercely for an instant, and then, scrambling
