Lesser Prairie-chicken (Tympanuchus pallidicinctus) - A Technical Conservation Assessment


The overall distribution of the lesser prairie-chicken (Tympanuchus pallidicinctus) has declined an estimated 92 percent since settlement by people of European descent and an estimated 78 percent since the early 1960s.
