That's quite good. I wonder what kind of anti-bird measures they use. Airports around the world use various measures, including employing professional hunters who basically shoot any large enough birds they see, trained hawks and other birds of prey (yes, it's true!) and various advanced scarecrows.

Given CPH's location - surrounded by the Baltic Sea from three directions with quite a strong tide I would imagine there are a lot of gulls and other seabirds in the vicinity.
