138 NEW YORK STATE MUSEUM 



This southern species, also known as the Marsh, Anghcan, or Nuttall 

 tern is an accidental siimmer visitant on the coast of this State. Giraud 

 and DeKay found it rare on the coast, but the latter says that it occurs 

 more frequently on the Great Lakes, a statement which I have been unable 

 to verify and it is certainly not true at the present time. A record of its 

 capture on Shinnecock bay, L. I., on July 8th, 1884, is given by Butcher, 

 Auk, volume 2, page 38; and on South Oyster bay, a pair on July 4, 1882, 

 Auk, volume i, page 34; also Point Lookout, Queens county, July i, 1885, 

 (S), Butcher's Long Island Notes. This cosmopolitan species breeds on 

 the Gulf and the South Atlantic coasts, as far north as southern New Jersey.

The Caspian tern was not mentioned by Giraud or BeKay as occurring 

 in the State. It is cosmopolitan in distribution and is a regular but rather 

 uncommon transient visitant both on the coast and the larger lakes of New 

 York. It breeds both south of us and far to the northward, but nowhere 

 within our borders. A curious fact noticed by several observers is that 

 they almost always appear in pairs on the autumn migration, a young bird 

 escorted by an old one.
