GLAUCOUS GULL. 
In summer the head, neck, lower back, tail and 
edge of the wings, and whole under plumage, pure 
white ; the mantle and wings pale grey ; quills 
crossed by a black bar, broad on the first but after- 
wards rapidly narrowing upon the others, and on 
the sixth scarcely an inch in breadth ; the first 
quill with a white tip ; the bill is a pale dull yel- 
low, angle of the mandible reddish orange ; legs 
and feet grey, tinted with light red. In winter 
the head is streaked with pale greyish brown. 
The next two birds closely resemble each other 
except in size, and also the Herring Gull, differing 
and both at once distinguished from the latter by 
the quills wanting the black at their extremities. An 
example will be seen in our next plate, representing 
THE GLAUCOUS GULL, 
Larus glaucus.
