among them. The species is migratory, however, even in 

 these mild climates. 



Along the coasts of Georgia and Florida Wilson observed 

 these Terns in numerous flocks in the month of July. They 

 were very noisy, and darted down headlong after small fish. 

 Birds of this species frequently settle on the rigging of ships at 

 sea, and, in common with their relatives, are called Noddies by 

 the sailors. 



The Sooty Tern occurs regularly north to the Carolinas, and oc- 

 casionally wanders to the shores of Massachusetts. It is almost 

 exclusively a sea-bird, feeding chiefly upon fish, which it catches by 

 swooping to the surface, not by dropping into the water. It rarely 

 floats upon the water, but its flight is powerful and rapid.
