AtlasGlobal TC-ATK Airbus A320-23 and Seagull #45,693 at CPH, july 2016.
Any aircraft on final at Copenhagen Airport might find themselves escorted (from a safe distance) by friendly seagulls, especially when landing from east, where the runway is close to the water.
Mostly the smaller aircraft, though. I have never seen them anywhere near the A380.
