In Japan „missbrauchen“ Rabenkrähen sogar Verkehrsampeln und Autos dazu, um Nüsse zu knacken: sobald die Ampel auf Rot schaltet, fliegen die Krähen mit einer Walnuss im Schnabel auf die Kreuzung und legen die Nuss schnell auf die Fahrbahn.



Während der nun folgenden Grünphase schauen sie dann zu, wie die Autos die Nuss zerdrücken. Beim nächsten Rot holen sie sich dann ihre Leckerei wieder ab.
