During the 1930s, the Skokie Swamp, north of Chicago, was converted into a series of wooded pools called the Skokie Lagoons. Extending from Dundee Rd. on the north to Winnetka Ave. on the south, the property encompasses 894 acres and is owned and managed by the Cook County Forest Preserve District.
The region has numerous parking areas, but the spot I visit most frequently is the Erickson Woods Picnic Grove, on the north side of Willow Rd., west of the southernmost lagoon and just east of the Edens Expressway (I-94). I usually walk through a mowed area, cross a bridge and a bike path, and then enter another mowed picnic area that opens onto the lagoon. Woods surround the opening, and a tree-covered island sits just to the north.
Birds can be thick in spring or fall anywhere in the area. Wood Ducks breed here, returning in March and remaining through late October. I like to make a loop, heading north along the lagoon for a while and then up-slope to the bike path, where I continue north until I come to another bridge that allows me to cross the creek and return back south. A leisurely walk in May can yield about 60 species. — Joel Greenberg
