CHAPTER II 



THE CORMORANT AND OTHER DIVERS 



IT has been necessary to write a somewhat 

 lengthy explanatory chapter so as to make 

 clear certain points in natural history as seen 

 from under the water. 



I now propose to describe the life history of 

 a few birds and animals without further detailed 

 reference to these points, on the presumption 

 that the reader has grasped their significance 

 from the introductory chapter. 



The name " divers " has been given by the 

 naturalist to certain sea-birds that either swim 

 or fly after their prey under the water. 



The British divers include the grebes, the 

 northern, black and red-throated divers, guille- 

 mots, razorbills, puffins and cormorants. 



The main diet of sea-birds consists of fish; 

 divers feed on fish almost exclusively, while gulls 

 take fish to a far greater extent than is generally 

 recognised.
