MIGRATION. 
393 
birds of passage of Northern Asia betake themselves 
during the winter season. No less adapted to the 
purpose are the shores of the Caspian Sea, Lake Ural, 
and also Japan, all which places are well adapted for a 
winter residence. I have grudged no pains in thoroughly- 
examining such works and statements of competent 
naturalists as I have had access to, and give to the 
reader the results of my researches. 
The following species visit the south of China during 
the migrating season:—the Imperial Eagle, Sea Eagle, 
Lanner, Peregrine Falcon, Hobby, Sparrow Hawk, Hen 
Harrier, Short-eared Owl, the Little Owl of Japan, Xotaka
