A wild crow that befriended a teacher in her own terrace now visits her regularly, enjoying treats, puzzles, and games of increasing complexity laid out by his human friend. The intelligent bird loves his visits so much that he even brings his family along with him.
German native Alexandra Rösch, 53, lives on the outskirts of Berlin. A male hooded crow, Kräri has been visiting her with his female partner, Kruu, for about five years now.
