Migrations. — British Isles. — Except for Scottish records no 

 evidence of migration, except those of quite a local character, but 

 in severe weather small flocks and single birds are noticed on coast 

 in various parts. 



Distribution. — Abroad. — ^Middle Scandinavia to south Europe and 

 Ural. Local forms have been separated from Corsica and Sardinia, 

 north-west Africa, south-east Europe, Persia, and Transcaspia, 

 but, though it is certain that southern and eastern birds are paler, 

 their distribution and relations to one another are not yet clearly 

 defined.
