Pre-registration with the leader is required, limit 12 participants. We'll visit a few spots that highlight the park's variety of habitats, staying within about 1/3 mile of the parking lot. New birders welcome. We'll seek summer residents, youngsters, and early migrants along the DuPage River, in the woods, at a field's edge, and among shade trees by the nature center. Trails are level and are grass/dirt/paved. Meet at the parking lot on 336 Knoch Knolls Rd., Naperville.Leader: Steve Constantelos, 630-890-8956, steve.constantelos@gmail.com
