Named after the French ornithologist Charles Lucien Bonaparte, the Bonaparte's gulls are North American birds of the Laridae family. The genus name is an amalgamation of the Greek terms 'chroikos' with 'kephalē' translating to 'color' and 'head' respectively.
The word indicates the appearance of the breeding adults of the species that exhibit a dark slate-black head. George Ord of Philadelphia designated the 'philadelphia' epithet to these gulls.
Migration is observed at the end of July stretching through to November when these gulls flock with the little gull, Ross's gull, and others to avoid the chilly winters. They navigate to a warmer climate, mostly near the coast.
These gray-white gulls are adept at preying on insects in flight while also diving and plucking out small fish and floating eggs from lakes and rivers. They're known to be kleptoparasites, stealing fish and insects from other birds like dunlins. However, the species is hunted down by hawks, ravens, and other predatory birds.
