Northwest Indiana Birding Opportunities - Willow Slough Fish & Wildlife Area

Willow Slough began with the purchase of 7,800 acres of land in 1949.

Land acquisition continued to bring the total size to 9,956 acres. J.C. Murphey Lake was completed in 1951. Today, despite the history of heavy agriculture and drainage in this area of the state, Willow Slough holds one of the highest diversity of birds compared with other state fish and wildlife properties, with over 250 species seen.

Willow Slough’s mosaic of habitats makes the property a year-round birding destination. But, like other fish and wildlife areas, park amenities are light, so those looking for lodging, food, or gas should prepare beforehand before entering the property. An outer loop of county roads cross through many of the park’s habitat, allowing for short walks to access much of the great birds to be seen.

The centerpiece, J.C. Murphey Lake, is an oasis within the region, often attracting thousands of migrating waterfowl, especially scaup and grebes. It remains the regional hotspot to see migrating American White Pelicans, and other larger birds with a water affinity can also be seen, including Bald Eagles, Osprey, and Sandhill Cranes. Visitors will want to stop near the park office to scan the lake. By mid-spring a large Purple Martin colony has returned, and they are easily observed here.

The northern areas of the lake support high quality wetlands, with breeding evidence for Common Gallinule, Virginia Rail, Least Bittern, and Marsh Wren. Farther north along the county roads, open grassland and oak savanna mosaics allow for Blue Grosbeaks, Bell’s Vireos, and Lark Sparrows. The southern loop road hosts other more traditionally southern nesting birds among the oak forests, including Summer Tanager and Kentucky Warbler. Here and elsewhere in the park is a local stronghold for whip-poor-wills as well; a rarity anywhere else in this region of the state.
