There's something otherworldly about the traditional Swedish musical style known as Kulning. Back in the day, the shrill and haunting singing was used to herd cows, but animals of all kinds apparently find it irresistible. When Swedish author-turned-animal-whisperer Åsa Larsson starts crooning, wild swans swim over to investigate the "magical" notes.
On the other hand, Monty the parrot can't seem to stay away from his "puzzle box" after a year apart. The clever bird knows it completely by heart!
