200 SANDWICH TERN. Class 1L 



this a cloven-footed gull, as the webs are de- 

 pressed in the middle, and form a crescent. 



T?hese birds frequent fresh waters, breed on 

 their banks, and lay three small eggs of a deep 

 olive color, much spotted with black. They 

 are found during spring and summer in vast 

 numbers in the fens of Lincolnshire ; male an 

 incessant noise, and feed as well on flies as 

 water insects and small fish. 



Birds of this species are seen very remote 

 from land. Kalm saw flocks of hundreds in 

 the Atlantic ocean, midway between England 

 and America, and a later voyager assured me 

 he saw one 240 leagues from the Lizard, in 

 the same ocean.
