Article Type: Paper
The previous sparse literature on Tongan seabirds is reviewed and is expanded by records made on 60 voyages through the area here described as Tongan waters. Of the 37 species thought to occur, 5 are passage migrants; breeding has been confirmed in 8 species and could occur in a further 8. Eight species are thought to be visiting and the status of another 8 requires confirmation.
