Navigators
With night falling, a large flock of Canada Geese soared high above - silent for once, and heading towards open water. There were no stars visible through the overcast sky and the shoreline below would have soon been obscured in the darkness. I can understand why they fly at night - with less turbulence in the air, no predators to contend with, and cooler temperatures to avoid overheating - it makes perfect sense. However, I don't understand what makes them such good navigators.
