Identification

POWERED BY MERLIN

Tropical tern with gray back, black cap, and white forehead. Nonbreeding and immatures have a messy dark nape. Most similar to Sooty Tern but paler gray above with more extensive white tail edges and paler undersides of flight feathers. Also compare with the paler Gray-backed Tern. Bridled Tern is found in warm tropical waters worldwide. It breeds on islands, usually concealed by a large rock or bush. Otherwise, usually stays far offshore, often seen perching on floating wood or debris. Rarely seen near land except when blown off course by a hurricane.
