I got these pictures from the Lewes, DE to Cape May, NJ ferry, its a 17 mile ferry ride across Delaware Bay.
The only northern member of the booby family, the Northern Gannet is one of the most spectacular sea birds. During migrations gannets may be observed offshore, either gliding above the water or diving into the sea after fish, sometimes plunging headlong from heights as great as 50 feet. They are pelagic, spending their whole life at sea except during breeding season.
Seeing them from the ferry is wonderful, a real up close look at birds you'll probably not otherwise ever get this close to!
