Through the years we have found a wide variety of fauna that can be difficult to observe, from birds such as Grasshopper and Henslow's Sparrows to many first county record dragonflies such as river cruisers (Macromia illinoiensis and taeniolata), Swamp Darner (Epiaeschna heros), Great Blue Skimmer (Libellula vibrans), and Citrine Forktail (Ischnura hastata).
