Even if the ducks killed weren’t from a protected species, anyone in Italy is required to have a hunting permit, even on private lands. This permit is almost impossible to get for a foreigner because it’s an exam with a lot of extremely specific questions in Italian
I get the racial stereotypation, but at least it should be funny.
Btw, taking a hunting license requires a medical exam (including psycho-physic evaluation), a basic zoology exam to recognize species, an exam on laws around hunting, one about nature preservation and one on weapons handling. It has to be renewed every 5 years.
Nothing too complicated, tons of idiots have it, but still quite a process.
