MURRE 
30. Uria troille. 16 inches. 
In summer the throat is brownish black, but in win- 
ter the throat and sides of head are white; feet blackish 
bill, long and stout, 1.7 in. dene while that of Brunnich 
Murre (Uria lomvia—No. 31), is shorter (1.25 in.) and 
more swollen. The ranges and habits of the two species 
are the same. Murres are very gregarious, nesting in 
large colonies on northern cliffs. In summer every ledge 
available at their nesting resort is lined with these 
birds, sitting upright on their single eggs.

Notes.—A hoarse imitation of their name “ murre.” 
Nest.—Their single eggs are laid upon the bare ledges 
of cliffs. They are pear ~shaped to prevent their rolling 
off when the bird leaves; greenish, gray or white in 
color, handsomely blotched or lined with blackish (3.40 
x 2.00). Their eggs present a greater diversity of color- 
ation and marking than those of any other bird. 
Range.—Breeds from the Magdalen Is. northward; 
28 winters south to Long Island.
