Bonaparte's Gull (Chroicocephalus philadelphia) lives in coastal wetlands. Bonaparte's gull is a small gull found mainly in North America.
Fascinating facts about the Bonaparte's Gull
- At just 28-38 cm long, Bonaparte's gull is one of the tiniest gulls in North America, only out-sized by the little gull and Saunders's gull. Adults weigh a feather-light 180-225 g and span 76-84 cm across the wings, giving them a sleek, tern-like silhouette that lets them dart through open water with ease. Their diminutive size lets them exploit narrow tree branches for nests.
- Bonaparte's gull builds its nest high in conifer trees, usually 3-6 m above ground and within 60 m of open water, a habit rare among gulls that typically nest on the ground. Nests are modest platforms about 25 cm across, spaced 30-50 m apart, and can be as far as 180 m from water.
- Bonaparte's gull eggs are tiny powerhouses: each measures 49 mm × 34 mm, weighs 28.5 g, and is laid in clutches of 2-4, most often three. Both parents share incubation duties for 22-24 days, but storms can devastate nests, one study in Churchill, Manitoba found over half the eggs blown out of nests, leaving only 42 % to hatch. Such weather-linked losses highlight the species' vulnerability to climate extremes.
- During the breeding season Bonaparte's gull turns into an insect-catching specialist, swarming in massive numbers to follow termite flight dispersals and hovering to snatch insects mid-air.
- Unlike most gulls, Bonaparte's gull often nests in trees, yet it will travel up to a kilometre to chase away humans that approach its nest, even tolerating human presence nearby; some pairs even choose to nest close to people.
