THE BIRD BOOK 
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 
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. Sizre 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. 
Iceland Gull 
Glaucous-winged Gull 
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.
