It seems that German police are busy during the summer answering complaints about noise. The noise being reported sounds a lot like people having very loud sex. Only it's not humans getting frisky, it's actually hedgehogs.
Police are frequently called out in the summer months to similar complaints about the noise. It reports that hedgehogs are among the loudest nocturnal animals, competing with cicadas, frogs and the caridean snapping shrimp. People often mistake hedgehogs mating with humans having really loud sex.
The hedgehog mating ritual is a lengthy affair, known in German as Igelkarussell, or hedgehog carrousel, and takes place over an area of around 500 square feet. Their most active period is between April and the beginning of September.
- Hedgehog experts warn police not to bother them and that they won't so much mind if you sit quietly and watch. The Hedgehog populations have dropped dramatically in recent years and are under threat so if you come across one having sex, don't bother them.
