GLAUCOUS GULL. 



as in other Gulls. In the perfect summer state the 

 whole plumage is white, excepting the back, scapu- 

 lars, and wing-coverts, which are a very light ash- 

 colour: the primary quill-feathers are still lighter, 

 the ends and under part being pure white : there is 

 no black whatsoever on any part of the plumage. 

 When arrived at maturity the beak is three inches 

 in length, of a lightish horn-colour, the angular pro- 

 jection of the lower mandible being bright red ; orbits 

 naked, straw-coloured, and very fierce ; legs and feet 

 a livid flesh colour." 



Inhabits the northern parts of Europe and Green- 

 land, and, according to Captain Sabine, also on the 

 British coasts. Like the rest of this genus it feeds 

 upon fish, and also on the smaller aquatic birds. 

 Captain S. observes, that one specimen which was 

 killed during the north-western expedition disgorged 

 a little Auk when it was struck, and proved, on dis- 

 section, to have a second in its stomach. Its eggs 

 are greenish, elongated at the tip, and marked with 

 six or eight black spots.
