The heath hen (Tympanuchus cupido cupido) was a distinctive subspecies of the greater prairie chicken, Tympanuchus cupido, a large North American bird in the grouse family, or possibly a distinct species, that became extinct in 1932. Heath hens lived in the scrubby heathland barrens of coastal North America from southernmost New Hampshire to northern Virginia in historical times, but possibly south to Florida prehistorically. The prairie chickens, Tympanuchus species, on the other hand, inhabited prairies from Texas north to Indiana and the Dakotas, and in earlier times in mid-southern Canada.
