The ‘ewa‘ewa or sooty tern is an abundant and gregarious tern (Family: Laridae) that lives in the tropical regions of both hemispheres, and is able to remain on the wing for years. Eight ‘ewa‘ewa (sooty tern) subspecies are recognized, and one (S. f. oahuensis) breeds in Hawai‘i. Individuals have long, slender wings and a deeply forked tail.

Wagtails are slender, often colourful, ground-feeding insectivores of open country in the Old World. Species of wagtail breed in Africa, Europe and Asia, some of which are fully or partially migratory. Two species also breed in western Alaska, and wintering birds may reach Australia.
