August 26, 2017 - Bonaparte’s Gull (Chroicocephalus philadelphia)

These small gulls breed in Canada and Alaska, migrating through much of the United States to winter in parts of the United States, Mexico, and the Caribbean. They eat small fish and large invertebrates, often catching insects in flight during the breeding season. Unlike most gulls, they frequently nest in trees, building open cup-shaped nests from branches, twigs, bark, moss, grasses, and lichens. Both parents probably incubate the eggs and feed the chicks.
