as in that species. 
The Florida cormorant is solely an inhabitant of the southern portion of the United States, 
not proceeding further to the north than Carolina. They congregate in thousands on the 
Florida keys at the season of reproduction, placing their nests on the mangrove bushes, many 
being established on the same tree. 
They are expert divers and fly with great rapidity.
