ONTARIO. 



This handsome little Falcon is a miniature of the Peregrine, 

 and is quite its equal in courage and spirit, often attacking 

 birds of much greater weight than itself. It is not a common 

 species anywhere, and in Southern Ontario can only be regarded 

 as a migratory visitor in spring and fall. It is at all 

 times a difficult matter to define the precise breeding range of 

 birds that are rare everywhere, and regarding the summer 

 haunts of the Pigeon Hawk we have yet much to learn. As it 

 has been known to breed in Maine, and in Alaska, it is quite 

 likely to breed also in Ontario, where there is plenty of room 

 for it to do so without being observed. In the fall 

 when the Blackbirds get together in flocks, they are frequently 

 followed by the Little Corporal who takes his tribute without 

 much ceremony. I once saw him " stoop " on a flock as 

 they hurried toward the marsh for shelter. How closely they 

 huddled together, as if seeking mutual protection, but he went 

 right through the flock and came out on the other side with one 

 in each fist !
