THESE 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 

 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 

 nlate is figured from it.
