The owner of an Audi A2 and Golf GTI in Worcestershire, England, thought that vandals were attacking his cars with pen knives but was shocked that the culprit was actually a cute little Chaffinch. He believes the territorial bird was attacking its own reflection. It had taken chunks out of the bodywork around the windows and mirrors of the cars. Ciaran Nelson, of the RSPB, said: "Garden birds are very protective of their territories, particularly males. Shiny cars or car windows often provoke a very aggressive response, because they think their reflections are really a rival bird. It’s just a primeval reaction."
