rjlHE present species builds on bare and barren 

 -L islands, both those of the sea-coast and those of 

 inland lakes, as well as on the margin of the mainland. 

 Steep and precipitous cliffs are used, as well as low 

 marshy moors and sandy places a little way inland. 



The nest is a tolerable quantity of grass, with 

 occasionally, though rarely, some sea-weed placed 

 loosely together in any slight hollow in the rock or 

 the adjacent herbage, the latter least frequently. 



The first or second week in June is the time of 

 building. 



The eggs, two, three, or four in number, are of 

 almost every variety of shade of green and brown, 

 olive green, olive-brown, and stone-colour, thickly 

 spotted with grey, brown of two shades, and brownish - 

 black.
