Snow Geese migrate every year between the tundras of Alaska and Canada to as far south as Mexico. They have become very efficient flyers, taking advantage of high thermal currents to move great distances. When they are not flying, they are foraging for food and eating their way across fields and swamp lands. Here are a few shots taken last month of these birds doing what they do best, flying. They were among a flock of several thousands at the Edwin B Forsythe National Wildlife Refuge, and all I had to do was point the camera up and click away.
