THIS species, which breeds on the coasts of Scotland and 

 Ireland, pairs about the middle of March, and the eggs 

 are laid in the beginning or more usually by the middle 

 of June. They are hatched in twenty-four days. The bird 

 sits very close, so as to be easily taken on the eggs. Two 

 or more couples have been known to lay under one piece 

 of rock. 



The bare earth, or rather the bare rock, or a crevice in it, 

 is the only bed sought for by this species for the purpose of 

 nidification. Mr. Hewitson writes as follows: "On some of 

 the islands which present a steep precipice to the sea, they 

 make use of holes or crevices in the rocks, in which the eggs 

 are laid at various distances from the mouth of the hole from 

 one or two feet, which is most usual, to three or four. On 

 other islands less precipitous, it deposits them in cavities under 

 or between fragments of rock and large stones, with which the 

 beach is strewed. In one place several pairs rear their young 

 ones in crannies between the stones which form the ruins of
