Now in its fourth year, Nature Notes is a 4½-minute weekly radio program produced by Marfa Public Radio in Marfa, Texas, in conjunction with the Chihuahuan Desert Research Institute in Fort Davis, Texas. This environmental program examines a little-known desert region in the United States and Mexico. But many desert-dwellers featured—such as turkey vultures and prairie dogs—will be familiar to listeners outside this region. Through interviews with scientists and field recordings, Nature Notesreveals the secrets of desert life.
