Uria lomvia arra (PALL.) RipGw. 1884. 
Wherever the coasts and islands of Alaska are bordered by 
rugged cliffs and rocky declivities, this bird is found in great 
abundance. It occurs at Kadiak and along the adjacent coasts 
from Sitka to the peninsula of Alaska. Common around the 
Prybiloff Islands and the other islands in Behring Sea, and in 
Norton Sound ; it breeds in small numbers in Chamisso Inlet 
and Kotzebue Sound and on the cliffs near Cape Lisburne. (/Ve/- 
son.) Extremely abundant at Bogoslov where they breed in 
millions,and throughout the Aleutian Islands. TZzrner.) Only 
reaches Point Barrow asa rare straggler. (Murdoch.) 
BREEDING Notes —This bird lays its single egg upon the points 
and narrow shelves, on the faces of the cliff-fronts of the Prybiloff 
Islands, straddling over the eggs side by side, as thickly as they 
can crowd, making no nests. Its curious straddling by which 
the egg is warmed and hatched lasts nearly twenty-eight days 
and then the young comes out with a dark thick coat of down, 
which is supplanted by the plumage and color of the old bird, in 
less than six weeks. (Ed/o?t.)

Michael Harbour many of these birds breed every year on the

pretense of anest. Only one egg is laid in a season if undis- 
turbed, but will be renewed if the season is not too far advanced. 
The egg is very large, having a bluish-green ground with dark- 
brown mottlings of variable outline. (Zwrner.)
