WHERE THE MIGRANTS GO. 241 



however, be borne in mind that many of the birds 

 from North-East Europe winter in Asia Minor, 

 Arabia, Persia, and Turkestan, whilst a considerable 

 contingent of birds from West Siberia find their 

 way south-west to Africa. It is highly probable, 

 however, that every one of our British summer 

 migrants either winters in the basin of the Medi- 

 terranean or in the two lower zones of Africa. 

 Some of them inhabit South Europe as well as 

 the middle zone of Africa, and others do not cross 

 the Mediterranean at all. 



It is rather noteworthy how many of the 

 British Birds of Prey are migratory " British " 

 implying those that undoubtedly breed in our 

 islands. The two greatest travellers are the 

 Hobby and Montagu's Harrier. Both these birds 

 are excessively rare with us, yet their migrations 

 are as regular and as interesting as those of much 

 commoner species, whose annual movements are 

 better understood. The winter home of these 

 two birds is in the lower zone of Africa, extending 

 to the Cape Colony. The species that winter not 

 quite so far away from us that is to say, in the 

 country between the equator and the Atlas Moun- 

 tains are the Kestrel, the Honey Buzzard, and 

 the Marsh Harrier ; whilst those that travel least 

 of all are the Osprey and the Hen Harrier, which 

 find a suitable winter haunt in the basin of the 

 Mediterranean, many individuals remaining on 

 the northern shores of that sea. The Ring Ousel 

 is the only other migrant the British examples of
