One of the signs that has gone up outside the Marlin Bar at Horseshoe Bay , Magnetic Island , due to Kookaburra attacks on outdoor tucker both there and in picnic shelters nearby . Our Shipping Reporter was patrolling the area recently when he witnessed a daring Kookaburra swoop down, grab some meat from a plate , and fly off with it to a young one nearby , giving the purloined sirloin a snake- killing and tenderising couple of whacks.
