Photo taken at Bosque del Apache NWR in 2016. I'll be there the following week, can't wait.
Geese fly in a "V" formation for several reasons. It conserves energy. Each bird flies slightly above the bird in front resulting in less wind resistance. The birds take turns being in front, falling to the back when they get tired. It enables the to fly longer distances by flying a a "V".
Bosque del Apache NWR is winter home to around 30,000 Snow geese. They are an awesome sight and sound when they lift off the water in the morning headed for planted fields to eat.
