Seagull cafeteria

      The big green and yellow John Deere tractor and plough have finished their job and departed the rich peaty field but the seagulls have homed in on a major feast.
      The photograph at the top shows only a small amount of seagulls that stretched from side to side right across the field.
      It must be hell down there in worm land with all those beaks searching the soil.
      How fast can you burrow worms?
