THE SANDWICH TERN.
+ Sterna cantiaca, Gmel.
PLATE CCCCXXXI.— Adult.
On the 26th of May, 1832, while sailing along the Florida Keys in Mr. Thrttston's barge, accompanied by his worthy pilot and my assistant, I observed a large flock of Terns, which, from their size and other circum- stances, I would have pronounced to be Marsh Terns, had not the difference in their manner of flight convinced me that they were of a species hitherto unknown to me. The pleasure which one feels on such an occasion cannot easily be described, and all that it is necessary for me to say on the subject at present is, that I begged to be rowed to them as quickly as possible. A nod and a wink from the pilot satisfied me that no time should be lost, and in a few minutes all the guns on board were in requisition. The birds fell around us; but as those that had not been injured remained hovering over their dead and dying companions, we continued to shoot until we procured a very considerable number. On examining the first individual picked up from the water, I perceived from the yellow point of its bill that it was different from any that I had previously seen, and accordingly shouted "A prize! a prize! a new bird to the American Fauna!" And so it was, good reader, for no person before had found the Sandwich Tern on any part of our coast. A large basket was filled with them, and we pursued our course. On opening several individuals, I found in the females eggs nearly ready for being laid. The males, too, manifested the usual symptoms of increased action in the organs distinctive of the sex. I felt a great desire to discover their breeding grounds, which I had the pleasure of doing in a few days after.
The vigour and activity of this bird while on wing afforded me great pleasure. Indeed its power of flight exceeds that of the Marsh Tern, which I consider as a closely allied species. While travelling, it advances by regular sharp flappings of its wings, which propel it forward much in the manner of the Passenger Pigeon, when, single and remote from a flock, it pushes on with redoubled speed. While plunging after the small mullets and other diminutive fishes that form the principal part of its food, it darts perpendicularly downwards with all the agility and force of the Common
