186 NOTES ON THE 
The flight of the Red-tailed Hawk is truly a marvel of dignity 
and grace equalled by few and excelled by no other species of 
bird. Who would have every sentiment of poetry in his nature 
awakened and ‘‘see God in his works,” let him watch its flight 
lovingly and reverently one hour.

BUTEO BOREALIS KRIDERIT Hoopes. (837a.) 
KRIDER’S HAWK. 
My attention had for some time been called to a white hawk 
by observing sportsmen, when one day Mr. G. W. Tinsley, a 
leading one of them of Minneapolis, brought me one that he had 
taken. Shortly another one was brought to me, which, after 
careful examination I decided was something new. About the 
same time I learned that Mr. Krider, of Philadelphia, while 
spending the summer in this section, had obtained several 
of these Hawks, and submitted them to Mr. Hoopes, of that 
city. Hoopes named the variety as above. During some years 
they are met with quite frequently, while in others I hear of 
none. The plumage varies exceedingly in the individuals that 
I have seen, but the presence of more or less white is its dis- 
tinguishing characteristic for varietal recognition. 
Having seen no nests, or seen no one who has, I can add no 
further facts in the history of this variety of the Red-tailed 
Hawk, except that they are less a prairie species than has 
been represented by some writers. On the contrary, I find 
them predisposed to neither prairies nor dense forests, but 
sparsely timbered openings. 
Note. Since writing the above, I have ascertained that this 
variety of the Red-tails has been observed in the vicinity of 
Lake Superior, at Red lake, Mille Lacs and Lake Traverse.
