FAIR ISLE, THE BRITISH HELIGOLAND 55 



species being modified, since they can no longer be 

 classed as ''rare casual visitors," which was formerly 

 their designation as members of our avifauna. 



The Sea Eagle is one of the birds of the past as a 

 native species. It formerly had an eyrie on the Sheep 

 Craig, but was banished sometime between the years 

 1825 and 1840. There is another site of a former eyrie, 

 but this was probably an alternative nesting-place of the 

 birds alluded to, and not the domain of a second pair. 



The question as to whether young and old birds 

 of the same species migrate in company is an interesting 

 one, and perhaps, as bearing upon it, the following short 

 list of birds which I have observed at Fair Isle so doing, 

 may be worth giving : — 



Rook, Starling, Siskin, Snow- Bunting, Wheatear, 

 Ring-Ouzel, Bluethroat, Bram.bling, White Wagtail, 

 Lapland Bunting, Swallow, Martin, Blackcap, Redstart, 

 Chaffinch, Wigeon, Mallard, Turnstone, Golden Plover, 

 Lapwing, Dunlin, Black-headed Gull, Common Gull, 

 and Iceland and Glaucous Gulls. 



A list of all the native and migratory birds known 

 to Fair Isle, with an indication of their times of arrival, 

 departure, and passage, will be found in a subsequent 

 chapter.
