Pre-registration not required.This site remains one of DuPage County’s premier birding spots. Walk around the marsh with us, approximately 3.25 miles, to check out resident species. We hope to see Red-headed Woodpeckers, Henslow's Sparrows, Eastern Meadowlarks, and some marsh & woodland species. Most of our walk will be on preserve limestone and earthen trails; wear appropriate shoes and clothing. Meet at the visitor parking lot on the north side of Mack Rd., located between Winfield Rd. and Rt. 59 in Warrenville.Leader: Kyle Wiktor, cell: 708-506-5186
