When thousands of Snow Geese are flying together, I imagine they must stay focused in order to avoid crashing into each other. The sight of a mass takeoff is just a marvel of nature.
Taken 2/26/11 in a field near Fort Indiantown Gap, Pennsylvania, USA. Sharon and I left Middle Creek in search of old barns and found a field filled with thousands of snow geese miles away.
