One of the great things about Loess Bluffs National Wildlife Refuge in Mound City, MO is the migration of birds. While it is a crazy place in the spring, fall isn't a bad time either. Here a small group of Snow Geese take to the air. The sounds in the air is amazing from all the duck and swans on the water. Lots of people driving around the wetland and taking photos.
