abundance. It occurs at Kadiak and along the adjacent coasts 
from Sitka to the peninsula of Alaska. Common around the 
Pribilof islands and the other islands in Bering 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. (Zwrner.) Only reaches

BREEDING Notes.-—This bird lays its single egg upon the points 
and narrow shelves on the faces of the cliff fronts of the Pribilof 
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 colour of the old bird, in less than 
six weeks. (E/hott.) See Palmer, ‘The Birds of the Pribilof 
Islands.” for full account of this bird. 
At Egg island, about ten miles from the entrance of St. 
Michael harbour many of these birds breed every year on the 
bluffs and ledges. The egg is laid on the bare rock without any 
pretence of a nest. 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. (Zurner.)  *
