Buteo pennsylvanicus. — Side by side with the Accipiter 
cooper il reared a Buteo pennsylvanicus of about the same age. 
The characters of the two birds were essentially different. The 
fierce aspect of the Accipiter showed itself quite early, and indi- 
cated by its every action its rapacity and daring. The Buteo, 
on the other hand, was mild in appearance and never exhibited 
the fierceness nor voracity of the Accipiter. 
But I succeeded better in petting the latter. It seemed to grow 
rapidly fond of my company. The Buteo, however, neither 
expressed pleasure, nor showed displeasure upon my coming 
near it, though it would make itself felt when one attempted to 
handle it. It never, however, used its claws with the same 
spirit as the Accipiter. I could handle the latter with impunity 
after it grew to know me. Strangers, it fought with spirit and 
resisted all their attempts at familiarity. The Buteo regarded 
all alike, seemingly neither as foes nor as friends. 
Its voracity was not nearly so great as that of the Cooper’s 
Hawk. It never at any time ate more than five Sparrows a day, 
and generally fewer than five. It, too, was more dainty in its 
feeding, nearly always pulling the feathers before eating. It was 
fond of insects, especially preferring grasshoppers, and ate frogs 
and fish with apparent relish. This the Accipiter did only when 
very hungry. 
If any preference was shown by these Hawks in the selection 
of food, it was for food in the form of warm birds. And I expe- 
rienced some difficulty in procuring enough Sparrows for them. 
I wished to supply in abundance the food they preferred, in 
order to make the conditions of their growth most favorable, 
and further to test their effect upon physical organization. The 
effects were apparent in larger size and more robust physique. 
The Buteo never fed in my presence with the same freedom 
that the Accipiter did, nor were its actions so free. The latter’s 
boldness and daring manifested themselves in every action.
