Pigeon Navigation: The sound of distant waves

Pigeons live in a different world, from The Economist:
Pigeons form a far richer picture of the world than a person can manage, through three senses unavailable to humans: an instinctive ability to navigate by the sun, an ability to detect magnetic fields that provides them with an inbuilt compass, and an ability to hear infrasound. But if local conditions mean they cannot hear their destination, they are as lost as a driver whose satnav has suddenly failed.
H/t Tyler Cowen.
