Southwest Indiana Birding Opportunities - Cane Ridge WMA | Tern Bar Slough WDCA

Cane Ridge Wildlife Management Area was created as a joint restoration project by the US Fish & Wildlife Service Duke EnergyHabitat Conservation Plan to provide a nesting area for the federally endangered “interior” Least Tern.

Black Necked Stilt


In addition to supporting a breeding colony of these birds, this 463-acre property also provides wetland habitat for migrating and wintering waterfowl, waders, shorebirds, gulls and terns. Cane Ridge is recognized as a Globally Important Bird Area by the National Audubon Society. Tern Bar Slough Wildlife Diversity Area lies immediately east of Cane Ridge, and consists of 840 acres of grassland, scrub and wetland habitat.

Total Birding Time:
1-3 hours. Most birding will be done from the county roads, or from the observation deck at Cane Ridge.

Best Times to Bird:
Cane Ridge and Tern Bar Slough can be productive any time of year. Spring and fall migration are obvious high points, but summer yields breeding Least Terns and grassland birds (and later, migrating shorebirds and herons), while winter into early spring sees a massive influx of waterfowl – especially Snow Geese, which occupy nearby Gibson Lake in the tens or even hundreds of thousands.
