Endangered - Piping Plover
The piping plover is probably a very rare fall migrant on the refuge. There are four known records, two on the Big Sandy Unit and two on the Duck River Unit. The most recent observation was made in 2010 in Pool 3 of the Duck River Bottoms.
All the piping plover sightings on the refuge are associated with the mudflats on Kentucky Lake. Efforts to protect this habitat for piping plovers and many other species of migratory birds are a priority of the refuge.
