GLAUCOUS GULL. 



BURGOMASTER. 

 Larus GLAUCUS. 



Char. Mantle pale pearl gray, rest of plumage white ; bill yellow, with 

 a ])atch of orange at the angle; legs and feet bright pink. Length about 

 32 inches , female somewhat smaller. 



In winter the head and neck are streaked with pale brownish gray. 

 Immature birds are mottled grayish brown and pale gray ; the first 

 plumage is the darkest. In the spring, before the young assume the pearl 

 mantle, their entire plumage becomes white. 



Nest. Usually on a cliff, sometimes on a low, grassy island or sandy 

 beach; a slight affair of seaweed or moss or grass. 



Eggs. 2-3 ; stone drab or olive buff, sometimes pale buff, marked with 

 brown and ashy gray ; average size about 3.00 X 2.00.
