THE NESTS AND EGGS 



OF 



NON-INDIGENOUS BRITISH BIRDS, 



Family CORVIDzE. Genus Nucifraga. 



NUTCRACKER. 



Nucifraga caryocatactes {Lhuiceus), 

 (British : Rare nomadic autumn migrant.) 



Single Brooded. Laying season, March to June, 

 according to latitude. 



Breeding AREA : Palaearctic region. The Nutcracker 

 breeds throughout the conifer forests of Europe and 

 Asia, almost as far north as the limits of forest growth, 

 and from the Atlantic to the Pacific. It breeds in the 

 forests of Scandinavia, south of about lat. 6f\ on various 

 islands in the Baltic, and thence across Russia and 

 Siberia to Kamtschatka and the Kurile Islands. South- 

 wards in Europe it is known to breed in East Prussia, in 

 the Black Forest, in the Alps and the Carpathians, and 

 possibly in the Pyrenees and the mountains of South 

 Spain. In Asia, although apparently absent from the 

 Caucasus, it breeds on the various southern and central 

 mountain ranges, but its distribution in the nesting 

 season is by no means clearly defined.
