THE KITTIWAKE GULL 287 



GLAUCOUS GUr.U, OR BURGOMASTER 



LARUS GLAUCUS 



General plumage white ; back ami wings bluish grey ; tail anil termina 

 portion of the quills Avhite ; bill strong, yellow ; legs livid Hesh-colour. 

 Young mottled with white, grey, and light brown ; shafts of the quills 

 white ; in other respects like the last, but the bill is longer and stouter. 

 Length about twenty-nine inches ; breadth iive feet two inches. Eggs 

 as in the last, but of a greener hue. 



The Glaucous Gull, a large, handsome, and powerful bird, resembles 

 in many of its habits the species last described, but it has not been 

 known to breed in even the most northerly of the British Isles. It 

 pays occasional visits to our shores in winter. A few specimens 

 only have been shot in the southern portion of the island, and no 

 large number in Scotland ; but in the neighbourhood of the whale 

 fishery it is common enough. It is very voracious, and not only 

 eats fish, whether dead or alive, and shares with the whale-fisher 

 in his booty, but pursues other sea-fowl, compels them to disgorge 

 their prey, robs them of their eggs, and, if they resist, kills and 

 devours them.-*- In short, it is the very tyrant of the Arctic Ocean. 

 Its predatory habits were noticed by the early navigators in these 

 waters, who gave it the name of Burgomaster ; but as no accurate 

 description of the bird was brought home, and as some of our other 

 large Gulls are open to a charge of similar rapacity, the name was 

 naturally transferred by WUlughby to another species, which he 

 calls the Wagel (probably the Great Black-Backed Gull in immature 

 plumage). This was in 1676. A hundred years later Brunnich 

 gave it the name of Glaucous Gull ; but it is still called Burgo- 

 master by the Dutch, and by Arctic voyagers generally. 



Mr. St. John gives the name of Wagel to the Great Grey Gull.
