Fig. 89. — A glimpse of Bird Key, Dry Tortugas, Florida, showing the vast 

 numbers of noddy and sooty terns, an estimated total of 75,000 to 80,000 

 birds. Due to the shifting of the coral sand forming the key, the house which 

 was located approximately at the center of the island is all but submerged.
