Viewers should plan to arrive early as the best viewing occurs at dawn. The event will proceed until the birds diminish their courtship dancing and booming, which is around 9:30 a.m. Prairie chickens were reintroduced to the area and each spring their courtship dances occur where their booming calls resonate across southern Iowa hills and valleys. Spotting scopes, binoculars, cameras and phones will be trained on capturing the images and sounds of the unique mating ritual that is part dance, part combat, and part haunting symphony. Iowa’s prairie chickens are only found in Ringgold County. ------------------------------------------------------------------------------------- Friday, April 14: Graceland University "Food Citizen Symposium 2017" at Shaw Center Carol Hall.
