Comparing the notes of this bird with those of the Common Tern, 

 Mr. Brewster writes : " Their notes are similar, but several of them 

 can be distinguished. The usual cry of S. macrura [= paradiscBa] cor- 

 responds to the tearr of S. hirundo, but is shriller, ending in a rising 

 .inflection, and sounding very like the squeal of a pig. The bird also 

 has a short, harsh note similar to that of Porster's Tern. At any dis- 

 tance within fair gun-range I could usually separate it from Wilson's 

 [= Common] Tern by its longer tail, and by the uniform and deeper 

 color of the bill. In flight and habits the two seemed to me identical "

JSgga, three, not distinguishable with certainty from those o{ S.forsteri qt

This species is found associated with colonies of Common Terns, 

 apparently making its nest among theirs. It is a less excitable, wilder 

 bird than hirundo, and . its single harsh note, cack, may be distinctly 

 heard above the uproar of Common Terns, as it hovers somewhat in
