r 1 1HESE birds resort for the purpose of incubation 

 -*- to the highest grassy parts of small rocky islands 

 and the kindred shores of the mainland, as also to 

 sandy places, where they breed in burrows, going in to 

 a depth of about two feet. The excavating of these 

 appears to occupy a considerable time. Both birds 

 sit, and that so closely as to allow themselves to be 

 taken in the hand. 



They appear to be very variable in the time of 

 laying, from the end of May to the end of June. 



The nest is at most and best but a slight collection 

 of fern leaves and withered stems of other plants; 

 frequently none is formed, but the sand alone suffices 

 the bird. 



Only one egg is produced; it is large in size in 

 proportion to the bulk of the bird, perfectly white, and 

 of an oval form, but both ends obtuse. 



This egg was taken by the Rev. H. B. Tristram, 

 in Orkney. The plate is figured from it.
