14. Horned Puffin. 
Fratercula corniculata (NavuM,) BRANDT. 1837. 
Coasts and islands of the North Pacific from the Kurile Islands 
to British Columbia. (A. O. U. List.) Breeding abundantly on 
all the rocky islands in Behring Sea. (JVelson.) This species is 
abundant on all the shore-line of Alaska, south of the Arctic circle, 
and in favored localities it abounds in incredible numbers. All 
the Aleutian Islands with their east and west extensions area con- 
tinuous breeding-ground of these birds for over 1000 milesjin 
length. The Prybiloff Islands, St. Matthew and St. Lawrence 
islands are also great breeding places. (Zwrner.) Common on 
the Prybiloff Islands. (/. 7. Macoun.) 
BREEDING Notes.—This mormon comes up from the south 
about May ioth to the Prybiloff Islands and always in pairs. It 
makes its nests of dried sea-ferns, grass and moss, slovenly laid 
together, far back in some deep or rocky crevice, where, when the 
egg is laid, it is ninety-nine times out of one hundred cases inac- 
cessible. The nest contains but a single egg, large, oblong, oval, 
and pure white. (£//o?t.) 
The nests of this species are placed on the ledges of the highest 
cliffs of those islands where foxes are found, and on islands where 
foxes are not found these birds breed generally at the base of the 
bluff under the large rocks which have become detached and 
fallen down. Their nests are composed of just whatever happens 
to be there, be it sticks, stones, or earth. A single egg of clear 
white colour is laid on the bare gravel or earth. The egg is very 
large for the size of the bird and when cooked is tolerable eating. 
The bird sits long at a time on the egg and does not leave it until 
hunger compels her to seek food. (Zzurner.)
