of Scotland, and a few occasionally stray as far southward as 
the Northumbrian coast, where I have obtained three or 
four specimens, but all in the immature plumage. Its habits 
are stated by Mr Epmonston to be more lively and active 
than those of the Glaucous Gull, and it displays more ele- 
gance of form. It is a common species in the Arctic Regions, 
and is mentioned by Sanrne and Ricnarpson as being plen- 
tiful in Baffin’s Bay, Davis Straits, and Melville Island. It 
is also common upon the Iceland coast, to which it is pro- 
bable many of those that winter with us, and in similar lati- 
tudes, retire to breed. It feeds upon fish, the flesh of whales, Food. 
and other carrion, and when upon our shores, is sometimes 
seen in company with the Black-backed Gull.
