For World Migratory Bird Day, we"ve journeyed down to Bosque del Apache National Wildlife Refuge in southern New Mexico to join a group of sandhill cranes and their mallard duck friends as they feed in shallow water. Each year beginning in late October, this 57,000-acre refuge becomes the winter home to tens of thousands of migratory birds including sandhill cranes and various species of geese and ducks who travel from as far away as Alaska and Siberia to hunker down in warmer climes. They stay until late February when they begin their journey back north to their summer homes.
