Also called the great-billed oriole, this species is confined to the island of São Tomé in the Gulf of Guinea. It favors forest canopies and can be shy, often heard by its rich whistles before being seen. Habitat loss from logging and agricultural expansion is the main threat. It sometimes uses shade-grown plantations where tall native trees remain.
