While weight offers a useful starting point, appearances can be deceiving—plumage, body shape, and leg length often make a bird look larger or smaller than its true size.
Birds Included in this Guide
This guide highlights birds closely associated with Tennessee’s wetlands. It features the classic wading species—herons, egrets, ibises, spoonbills, storks, and others—along with additional birds that, while not strict “waders,” are still strongly tied to marshes, swamps, ponds, and coastal wetlands.
Wetland birds included in this guide are rarely the only ones found in the marsh.

Tennessee Wetlands
In Tennessee, wetlands cover approximately 318,490 hectares (roughly 787,000 acres), representing nearly
of the state’s total land area.
- Seismic Origins: Reelfoot Lake, the state’s most iconic wetland, was created by the 1811-1812 New Madrid earthquakes, which caused the Tennessee River to flow backward and submerge a cypress forest. This unique ecosystem now hosts one of the highest wintering concentrations of Bald Eagles in the eastern United States.
- Vital Migration Corridor: The bottomland hardwood forests and marshes of West Tennessee serve as a critical link in the Tennessee Flyway. These habitats support over 300 bird species and provide essential wintering grounds for hundreds of thousands of migratory waterfowl, including mallards and wood ducks.
- Historical Loss: Since the late 1700s, Tennessee has lost approximately
- of its original wetland acreage, largely due to land conversion for agriculture in the western portion of the state.
Wetlands constitute less than 5% of the land area of the contiguous United States.

Foraging Strategy and Habitat use as tools to Identify Tennessee Wetland Birds
Even though many birds share wetlands, they don’t all feed in the same way. Each species uses specific strategies—diving, wading, probing mud, or hunting from the air—based on its food preferences and adaptations. For birdwatchers, knowing these foraging groups helps predict where certain species are most likely to be found in a wetland, making it easier to spot and identify them.
The table below summarizes the main foraging groups of Tennessee’s wetland birds, their preferred habitats, and representative species.
| Foraging Group | General Description of Strategy | Preferred Habitat Type | Representative Species |
| Diving Birds | Forage by diving beneath the water’s surface to find food. | Open, deep water (lakes, rivers, coastal areas) | Grebes, cormorants, anhingas |
| Open Water Waders | Forage by wading in shallow water with low-density vegetation. | Shallow water with low vegetation | Herons, egrets, ibises, storks, cranes, spoonbills, avocets, stilts |
| Dense Vegetation Waders | Forage by wading in shallow water surrounded by dense vegetation. | Shallow water with dense vegetation | Night herons, green herons, bitterns, rails, limpkin |
| Dipping/Dabbling Foragers | Forage by surface dipping or “tipping” in shallow water. | Shallow water, ponds, marshes with dense vegetation | Coots, gallinules |
| Moist-soil Foragers | Forage in muddy or moist-soil areas along the shoreline. | Muddy areas, moist soil, shorelines | Ibises, killdeer, rails, gallinules |
| Aerial Piscivores/snail eaters | Use perches or flight to spot and dive for prey. | Open water, often near perches or trees | Terns, kingfishers, eagles, osprey |
Tennessee Wetland Bird Hotspots: Top 5 Locations for Viewing
Tennessee’s diverse aquatic habitats support substantial concentrations of herons, rails, coots, grebes, and others. From the seismic cypress swamps of the west to the riverine impoundments of the east, these wetlands provide vital sanctuary for a spectacular array of migratory and resident waterbirds.
Reelfoot Lake State Park: Located in the northwest corner, this unique flooded cypress forest was created by earthquakes. Its shallow waters and stump-filled basins attract massive wintering populations of Bald Eagles, American White Pelicans, and Wood Ducks, making it a legendary destination for waterbird enthusiasts.
Tennessee National Wildlife Refuge: Situated along the Tennessee River in Middle Tennessee, this sprawling refuge features managed impoundments and mudflats. It is a critical stopover for migratory species, regularly hosting thousands of Sandhill Cranes, Northern Pintails, and American Coots during the peak wintering season.
Seven Islands State Birding Park: Located in East Tennessee near Knoxville, this park features restored wetland meadows and riparian borders along the French Broad River. The diverse habitat is excellent for spotting Yellow-crowned Night-Herons, Sora, and various species of Grebes during spring and fall migrations.
Hatchie National Wildlife Refuge: Positioned in West Tennessee, this refuge encompasses the last unchannelized river in the lower Mississippi Valley. Its bottomland hardwood forests and oxbow lakes provide essential nesting and foraging habitat for Prothonotary Warblers, Great Egrets, and the elusive King Rail.
Duck River Unit (Tennessee NWR): Found at the confluence of the Duck and Tennessee Rivers, this site offers extensive agricultural fields and wetlands. It is famous for attracting high concentrations of Greater White-fronted Geese, Black-necked Stilts, and Least Bitterns within its diverse freshwater ecosystem.
