OG 
GUILLEMOT, COMMON. 
Foontsu GUILLEMOT. 
URIA TROILE, Lath. 
The Common Guillemot is found in various parts 
of the northern hemisphere, including Great Britain, 
Many individuals of this species remain on our 
coasts during winter, and in summer are met with 
in vast numbers on particular rocks, either on the 
coast or in islands, where they may be seen stand- 
ing in rows, nearly erect, on the ledges, or sitting 
on theiregg. The Common Guillemot builds no 
nest, but deposits its eggs on the bare rock. The 
egos are extremely large, three inches and a quarter 
in length and two inches in breadth, pear-shaped 
and rough on the surface. Some are white, marked 
with a greenish blue; others verdigris green, 
marked with lines and spots of dusky brown. The 
young seldom go to the water until well grown.
