Snow geese breed up in the arctic and subarctic tundra of Canada and Alaska. They usually nest close to a pond, lake or near the coast. They look for nesting areas that lose their snow early so that they can avoid some of the flooding that comes from the spring thaw. They winter primarily in coastal areas of the US and Mexico, although there is a large population that migrates to the south central US to places such as the Bosque del Apache where this photo was taken. They often stop to feed at farm fields during migration.
