Syrnium nebulosum. — Lastly I bad a juvenile Barred Owl 
in my possession. In it, as in the others, abundance of food pro- 
duced the same effects — larger size and more robust organization. 
The food most preferred was birds and small rodents ; frogs and 
fish were eaten when quite fresh, though the latter were taken 
only when hungry. Insects, too, were eaten. 
Digestion was rapid, requiring about one and a half hours for 
the digestion and absorption of a pair of Sparrows. Birds were 
always eaten without pulling a feather. If not too large they 
were swallowed whole, for the throats of young Owls are quite 
capacious. The indigestible parts are ejected when digestion is 
completed. 
The Owl never, except once, fed knowingly in my presence 
(and it was difficult to observe its habits without its knowledge). 
Its sense of sight is so acute, and its range of vision so extended, 
that I was compelled to use many devices to deceive the bird and 
accomplish my purpose of observation without being observed. 
The food put into its cage was seldom eaten until pressed by 
hunger, and the bird never ate in a day more than one-third the 
quantity of food eaten by the Accipiter in the same time. 
It could not easily be petted, nor did it acquire a fondness for 
being handled. Indeed it seemed to remain unaffected by kind- 
ness, and to love solitude. T h „„„
