Once known as the Skokie Marsh, this area was converted into a chain of lagoons and islands extending from Willow Road north to Dundee Road. Each fall virtually all of the warblers that regularly move through the region are reported in the lagoons. It is also a haven for migrating cuckoos, flycatchers, vireos, thrushes and other species.

Cost for event entry is $10. Urban Birding Festival registration is $30.
