NON-INDIGENOUS BRITISH BIRDS. 21 



pole that occur within the area of the British Islands, but 

 do not differ in colour or character of markings. The 

 locality is a tolerably safe guide to their identification, if 

 it can be relied upon. 



Family FRTNGILLID.-E. Genus Calcarius. 



Sub- family EMBERIZIN^. 



LAPLAND BUNTING. 



Calcarius lapponicus {Linnccus). 



(British : Rare abnormal autumn migrant.) 



Single Brooded. Laying season, June. 



Breeding area : Northern Nearctic and Palaearctic 

 regions. The Lapland Bunting breeds on the tundras 

 and barren grounds above the limit of forest growth in 

 Europe, Asia, and North America, and in a similar 

 region at high elevations in various parts of the Dovre 

 Fjeld in Norway. Singularly enough it is not known to 

 breed in Iceland, Spitzbergen, or Nova Zembla, but is 

 common across Northern Europe and Asia, in Europe 

 extending as far north as continental land exists, but in 

 Asia not apparently beyond about lat. 73°. In Greenland 

 it breeds as far north as lat. 70'', and is said to be 

 abundant in the Arctic regions of the New World from 

 Alaska eastwards. 



Breeding habits : The Lapland Bunting is another 

 typical boreal species, only breeding on the treeless 

 wastes of the north, above the limits of forest growth — 

 on the Arctic prairies or flower-decked moors that stretch 

 away beyond the forests to the shores of the Polar seas.
