Saturday. This unique trip will allow you a great chance to see Whip-poor-wills, a bird in serious decline, after hours in the South Unit of the State Park. Meet at 7:00 pm at the Nature Center parking lot to bird the area for local nesters prior to looking for the Whip-poor-wills. The Nature Center entrance is just west of the Illinois Beach Resort in the South Unit. Leader: Sulli Gibson and Joel Greenberg.
