April 6 - June 29

7:00-8:30 AM


In addition to this schedule, on Friday mornings in spring join the naturalists from Retzer Nature Center and Benjamin Goss Bird Club as we set out to discover who’s chirping on the trails. We’ll explore habitats, welcome back spring migrants and check on our year-round residents. Binoculars are available on a limited basis. No reservations needed. Meet in the parking lot.

5:30 or 6:30 AM



Meet at 5:30 or 6:30 AM in the parking lot on the north side of Henneberry Drive, just west of Cty Y in Muskego. People who are there at 5:30 will walk some of the trails and return to the parking lot at 6:30 so later arrivals can join us. At that time we'll begin a roughly 2-mile walk over mostly level terrain, but be prepared for wet and/or muddy trails. Engel can be good for a variety of migrants including flycatchers, warblers, waterfowl, and shorebirds if the water level is right.

8:00 AM


Meet at 8:00 AM at Harnischfeger Park located at the end of Crawfish Road west of Ashippun. While Prothonotary Warblers can be heard from the boat launch, many more wonderful gems can be seen and heard from on the water - nesting Barn and Cliff swallows, Bald Eagles, Great Blue Herons, kingfishers, Spotted Sandpipers, pewees, orioles, flycatchers, vireos, and more! We will spend at least 2 to 3 hours on the water paddling approximately 5 miles one way. We'll park some of our vehicles at the take-out point at the Kaul Park boat launch so we don't have to paddle back upstream! In case of rain on Saturday, June 9, we'll plan the outing for Sunday, June 10.
