Marine Biologist Brendon Dunphy explains why the Hauraki Gulf is seeing increasing numbers of stressed shearwaters and albatrosses.
He says the food chain for tītī, or sooty shearwaters - also known as muttonbirds - , is being affected by rising water temperatures.
Dr Dunphy says some Hauraki Gulf birds are showing some worrying symptoms which relate to the rapidly warming planet.
