THE LAUGHING GULL. 535 



The Caspian Tern (Sterna caspid), a much larger species 

 even than the Royal Tern of the South Atlantic, must be 

 found on the coast of Nova Scotia in the migrations, for it 

 breeds far to the north, and "must be considered a regular 

 visitor every season, and one by no means uncommon," 

 on the New England Coast. 



THE LAUGHING GULL, 



Amidst the clouds of Terns on Flat Island could be seen 

 some eight or ten Black-headed or Laughing Gulls {Larus

 Indian Squaw, and giving marked propriety to the name of 

 the bird. I was much surprised to find this so-called 

 southern species so far north. Mr. Everett Smith, of Port- 

 land, Maine, had given me no encouragement as to finding 

 it about the coast of that State; and Mr. J. N. Clark, of 

 Saybrook, Conn^ thought it but an uncertain resident in
