44. Glaucous-winged Gull. Larus 

 glaucescens. 



Range. — North Pacific coast, breeding from 

 British Columbia northwards and wintering from 

 the same country to southern California. 



This Gull is very like the preceding except 

 that the primaries are the same color as the 

 mantle, and are tipped with white. Length about 

 27 inches. Not so northerly distributed a bird 

 as the previous ones, and consequently better

Iceland Gull 

 Glaucous -winged 



Gull 



V , ; % 



Pale greenish brown 



known. They breed in large numbers both on 

 the high rocky cliffs of the islands along the 

 coast and on the low sandy islands of the Aleu- 

 tian Chain. On Copper Island they breed on the 

 inaccessible cliffs overhanging the water. As in 

 the case of the Iceland Gull, when the nests are 

 on the cliffs, a large nest of seaweed is made, 

 whereas if they are on the ground, especially in 

 sandy places no attempt is made at nest-building. The eggs have a greenish 

 brown ground color and dark brown spots. Size 2.75 x 2.05. Data. — West Coast 

 of Vancouver Island. June 20, 1896. Three eggs; nest made of seaweed. 

 Located on a low ledge. Collector, Dr. Newcombe. 



45. Kumlien's Gull. Larus Kumlieni. 



Range. — North Atlantic coast, breeding in Cumberland Sound and wintering 

 as far south as Long Island. 



This bird differs from the Glaucous-winged only in the pattern of the gray 

 markings of the primaries and in having a little lighter mantle. It is quite 

 common in its breeding haunts where it places its nest high up on the ledges 

 of the cliffs. The eggs are not different apparently from glaucescens. 



46. Nelson's Gull. Larus nelsoni. 



Range. — Coast of Alaska. 



Plumage exactly like that of Kumlien Gull and questionably a new species. 

 The nests and eggs are not to be distinguished from the preceding.
