The Eagle Owl. 



The Hawk or Canada Owl inhabits the Arctic portion* 

 of Asia and America. Its head is not so round, nor is its face so 

 broad, as those of the other owls, from which it is also distin- 

 guished by its habit of hunting by day. In face it bears some 

 resemblance to the harriers. It builds in trees, and lays two eggs 

 — white, as are those of all owls. The eggs of owls are easily 

 distinguished from other white eggs by a peculiar roughness of 

 surface, which cannot be mistaken. The length of the Hawk Owl 

 is from fifteen to eighteen inches. 



The Snowy Owl is properly an inhabitant of the north of 

 Europe, but has more than once been discovered in Great Britain
