the next species are even vaster than in our northern 

 islands. The Tarne Islands, where the eggs Hterally 

 cover the flat tops of the "Pinnacle" Stacks, and 

 Flamborough Head in Yorkshire, are especially well- 

 known localities. The beautiful large pear-shaped eggs 

 are green, blue, or white, with various spottings or 

 scrawhngs of black or red-brown. Ordinarily the birds 



Guillemots on the "Pinnacles " 



lay them on ledges almost too narrow for safety, while 

 the successive rows of sitting Guillemots are a feature 

 of many a precipitous northern cliff. In general habits 

 they resemble the Razorbill, but in colour they are 

 browner with a non-compressed bill. The egg never 

 has a green lining-membrane, as in that species. 

 Neither bird makes the slightest attempt at a nest.
