The humble pigeon is anything but "common" to those who know the true nature of these birds. This bird is so enamored by some that, for over six thousand years, people have devoted themselves to the art of pigeon flying and pigeon breeding. Across the world, from the cities of America to China, enthusiasts have lovingly nurtured their flocks, creating thousands of breeds from small to large, and admired their beauty in every shape and size: pigeons with crests and frills, those who fly and those who can't.
