Bonaparte's Gull

Bonaparte’s Gull is one of only five black-headed gulls in North America. With its light body and long wings it is likely to be mistaken for a tern. Unlike many gull species, Bonaparte’s Gull is not a scavenger and is rarely found at rubbish tips. Feeding is done on the wing or by picking up food while swimming or wading. Its preferred diet is plankton, crustaceans, insects and fish.
