company with the Razor-bill, Guillemot, and Puffin. 



The nest is a mixture of grass and other dry 

 herbage with sea-weed. 



The time for laying is the latter end of May, or 

 the beginning of June. 



The eggs are usually two, but occasionally, though 

 very rarely, three in number. They differ much in 

 their colouring and markings; the prevailing tint is 

 stone-colour with a tinge of olive, much spotted with 

 grey and brown of two shades; or greyish-white faintly 

 tinged with brown, and blotted with dark brown and 

 purple grey.
