Bonaparte's Gull is the most tern-like of North American gulls, with buoyant flight and a delicate appearance. Named for the French naturalist Charles Lucien Bonaparte, it nests in boreal spruce forests — the only North American gull that regularly nests in trees. Breeding birds have a neat black hood. It often gathers in enormous concentrations at Niagara Falls and other river outlets.
