MD Osprey:

Many birders will closely inspect each Sandwich Tern encountered in 
North America to make sure it's not the South American subspecies, 
CayenneTern, especially in case of any future split. Sight records of 
Cayenne Terns have been recorded from North Carolina.

Well, now the British BOU Taxonomy Committee has recommended 
splitting the Sandwich Tern, that we see here, from the Old World's 
Cabot's Tern; one of which <may> have been recorded last year in 
Chicago. This split prompted Greg Neise to undertake an excellent 
analysis of these two taxa.

Since Cabot's could possibly show up in our region, his analysis is 
of interest. It can be found at the link in his message, below ...
