An intimate view of a mated pair of Northern gannets , Morus bassanus, fou de bassin, at their nest on Bonaventure Island, Quebec, Canada. Fencing is a behavior (pair bonding) used by Gannets to greet each other once reunited. Morus bassanus formerly: Sula bassana, Pelecanus bassanus. Bonaventure Island on the Gaspe Peninsula of Quebec is home to the largest Northern Gannet, Morus bassanus, Colony in the world and is the place to go to see large numbers of this species. Often seen off of the East and Gulf coasts of the United States in winter, the spectacle of the Bonaventure Island gannetry should not be missed.One of the largest seabirds of the North Atlantic, the gannet is a long-winged bird that plunges spectacularly into the sea in pursuit of fish. Nesting colonies are on northern sea cliffs; one at Bonaventure Island, Quebec, has become a famous tourist destination. In winter off southern coastlines, the gleaming white adults may be outnumbered by brown and patchy immatures; it takes four years for gannets to attain full adult plumage.Field MarksA goose-sized white seabird with extensive black wing ends. Scales over the ocean and plunges headlong for fish. Much larger than Herring Gull, with a pointed tail, longer neck, larger bill (often pointed toward the water). Immature is dusky, but note the "pointed at both ends" shape. Young birds in transition may have a splotched piebald look.
