An innovative amphibious boat, reminiscent of a vessel that might be used by Bear Grylls, is assisting RSPB wardens on Coquet Island in caring for the UK’s only breeding colony of roseate terns. These endangered birds nest on the island each spring, but wardens face challenges accessing it due to the lack of a safe mooring point or harbor at low tide, limiting boat access to high tide only. This situation complicates the logistics for the wardens, who reside in the island’s lighthouse, as they manage their duties around inconvenient boat schedules.
