24 WHITE'S THEUSH. 



in Europe can only be considered accidental, though acci- 

 dents of this kind happen regularly. After the breeding 

 season is over in the Arctic regions, the great stream of 

 migration which passes from north to south through Central 

 Siberia appears to divide before it reaches the mountains of 

 Mongolia, to avoid the deserts beyond. Some species of 

 the birds turn east and others west ; and of the species 

 which Nature has ordained to winter east, some individuals, 

 probably for the most part young birds who have never 

 migrated before, lose their way and get into the wrong 

 stream, and thus find their way into Europe as strangers 

 from the East, some of whom fall into Gaetke's hands on 

 Heligoland every year. The breeding ground and true 

 home of this fine Thrush is South- Central and South- 

 Eastern Siberia and North China. It winters in South 

 Japan, South-West China, and the Philippine Islands, occa- 

 sionally straying as far west as Sumatra." ^ 



This bird was named White's Thrush in honour of the 

 Eev. Gilbert White, whose memory is dear to ornithologists, 

 and whose Natural History of Selhorne is a perennial source 

 of delight to all lovers of Nature.
