This black-fronted tern (Chlidonias albostriatus) was one of a flock swooping around the Motueka River bridge feeding on flying insects. Black-fronted terns are regarded as primarily a species of the eastern and southern coasts of the South Island, breeding on braided rivers, then moving to the coast outside of the breeding season. The Motueka and Buller River populations are regarded as outliers.
