Scientific name: Larus philadelphia
The Bonaparte’s Gull nests in remote areas of Canada and Alaska, and is the only gull that nearly always nests in trees. Young Bonaparte’s Gulls jump out of the nest when only a week or less old, and in late July they begin migrating south shortly before the adults.
Bonaparte’s Gulls are quite small for a gull, and are very graceful in flight. If a predator or human approaches a nest, the adults will often dive-bomb the intruder while giving alarm calls that sometimes attract other bird species.
