Pinnated Grouse

At one time, the eerie hollow moaning of male prairie-chickens displaying on their spring 'booming grounds' was a common sound across much of central and eastern North America. Today the prairie-chickens are quite uncommon and localized; the race on the Atlantic seaboard, called the Heath Hen, became extinct in 1932. Greater Prairie-Chickens still thrive on a few areas of native grassland in the midwest.
