10 NESTS AND EGGS OF 



blufifs ; two birds are often found sitting, each on its eggy in the same 

 burrow. The eggs are deposited late in June and in July. Mr. Frazar 

 found these birds abundant on the coast of Labrador. An island of 

 two or three hundred acres in extent was covered with Puffin burrows ; 

 about a thousand nests examined contained one egg each, while in a 

 dozen others there were but two eggs to a nest. The greater part 

 of these were plain, dull white ; others were more or less thickly- 

 spotted, with obscure chocolate and reddish-brown markings ; a num- 

 ber had distinct brown spots, blotches and tracings, such as are seen in 

 the Murre eggs.* The sizes range from 2.25 to 2.85 in length by 1.45 

 to 1.85 in breadth.

liarge-billed Puffin. 



Hab. Coasts and islands of the Arctic Ocean, from Spitzbergen to Baffin's Bay. 



This bird is like the last, but greater in size, the bill larger and 

 differently shaped. It breeds in the far north, on the islands of Baffin's 

 Bay and along the coasts of Greenland — nesting in the same manner 

 as arctica. The eggs are not distinguishable. According to Prof. 

 Ridgway they average larger than F. arctica.-\

""^^ * Horned Puffin. 



Hab. Coasts and islands of the North Pacific, from Kurile Islands to Sitka. 



The Horned Puffin breeds on the bleak rocky islands of 

 the polar seas. It is found along the coast of Alaska, is common in 

 the Northern Pacific Ocean and on nearly all the islands of Behring's 

 Sea. It takes its name from the slender, upright horns of the upper 

 eye-lids. The term "horns," however, is regarded by some as mis- 

 leading. In the living bird the horns are said to be only soft, flexible 

 caruncles or wattles. The nest-holes of this species are in the deep, 

 narrow interstices of rocks, seldom within the reach of a man's arm, 

 and, except in the absence of the bird, it is hazardous to attempt to 

 rob the nest. Like the Tufted Puffin, Lunda cirrhata it often inflicts a 

 severe wound with its powerful bill. The nest cavities are lined with 

 grass, moss, etc. A single egg is laid, which is oblong-oval in shape, 

 pure white in color and the shell is rough, measuring 2.74 x 1.84.
