Tympanuchus pallidicinctus, commonly known as the lesser prairie-chicken, is a type of bird that is native to the grasslands of the southwestern United States. Synonyms for this species include the following: Tympanuchus cupido pallidicinctus, Tympanuchus cupido attwateri, Tympanuchus pallidicinctus attwateri, and Tympanuchus pallidicinctus pinnatus. This bird is known for its distinctive mating dance, which involves inflating its air sacs and making a series of hooting sounds. Unfortunately, habitat loss and other factors have led to a decline in the population of the lesser prairie-chicken, and it is now considered a threatened species. Efforts are underway to protect its habitat and ensure its survival for future generations.
