The Bonaparte's Gull was named not for the French general, but for his nephew, the zoologist Charles Lucien Bonaparte. This gull is a winter resident along the Atlantic Coast, where it feasts on fish, crustaceans, and other marine life. On its Canadian breeding grounds, it subsists mostly on insects, often taking them on the wing. It also nests in trees, an unusual habit among gulls.
In winter, most easily found at the Ocean City Inlet. In spring migration, can be abundant along Back River and the Susquehanna River.
Large flocks sometimes attract vagrant Little Gulls, Black-headed Gulls, and others.
