1'ilK PEREGRINE PALCi 'X. 



General Range. — Arctic America, breeding from Newfoundland northward, 



anil migrating in winter to the northern borders of tbe United States. Occasional 

 in England. 



Range in Ohio. — Very rare, or casual in winter. 



THIS rare winter visitor looks and acts like a Hawk, and is strictly 

 diurnal in its habits, but it has the soft noiseless plumage which marks the 

 Owls. When seen southerly it is most frequently at look-out upon the top 

 of a stub. If frightened, it dives down almost to the ground before taking- 

 rapid flight. 



Its food consists chiefly of insects and rodents, but it is a spirited bird 

 and quite equal to despatching game of good size. 



The nest is said to be frequently made upon the top of broken stubs. 

 Others are in natural cavities in trees, and others still are placed in the thick 

 foliage of pine trees, well up. 



'The note is a shrill cry which is uttered generally while the bird is 

 on the wing" (Fisher). 



No. 172.
