A medium-sized East Asian gull with a distinctive black band near the tip of its tail, classed as rare/accidental in Borneo where it appears far south of its usual wintering range.
A generalist coastal feeder taking fish, carrion and refuse around harbours, and any record in Bornean waters likely represents a storm-displaced or exceptionally wide-ranging individual.
