Join us to bird one of the most important sites for biodiversity in Illinois, named for the waterway known as the Middle Fork of the North Branch of the Chicago River that transects the property. Featuring a rare tallgrass savanna ecosystem as well as wetland, woodlands, prairies and open fields, this preserve is a prime spot for viewing fall migrants like Fox, White-crowned and Lincoln’s Sparrows as well as Sandhill Cranes, Wilson’s Snipe, Northern Harrier and a variety of migrating waterfowl. Special mid-October sightings in recent years have included Harris’ Sparrow, Purple Finch and the spectacle of hundreds of undulating Pine Siskins swooping over the fields. European Goldfinch are also becoming increasingly common sightings here.

Directions: The preserve is located at 1401 Middlefork Dr in Lake Forest. From Route 60, take Route 43 north to Westmoreland Dr./Middlefork Dr. Turn left to the parking lot.

Leaders: Charlotte Pavelka and Doug Reitz (847) 347-8416
