Horicon Marsh NWR
Sunday, August 09, 2026 

We’ll bird various areas around the marsh, including Highway 49 and the Auto Tour.  The group usually hikes 2-3 miles on Old Marsh Road, with other spots visited via car caravan – either from west or east end, depending on recent activity.  We expect to find a nice variety of marsh birds (terns, rails and herons), shorebirds and waterfowl, as well as an assortment of resident passerines (including Yellow-headed Blackbird) and possibly early-fall migrants.

To register, check back here closer to the trip date. Please note that pre-registration on the WSO website is now required for field trip attendees, which includes the signing of waivers. Trip details will be emailed to registrants (including the link to a Google map) a few days prior to that event.
