North Dakota offers some of the most spectacular birdwatching opportunities in the United States, primarily due to its pivotal location within the Central Flyway migration route and its landscape dominated by the Prairie Pothole Region. Often referred to as America’s "duck factory," the state's vast expanses of mixed-grass prairie and countless small wetlands create essential breeding and staging grounds for millions of birds. With more National Wildlife Refuges (NWRs)—63 in total—than any other state, North Dakota is an essential destination for any serious birder or wildlife enthusiast.
Audubon NWR, established on the southern portion of Lake Audubon, is a major stopover for hundreds of thousands of waterfowl, including ducks, geese, and Sandhill Cranes, during the spring and fall migrations. It provides diverse habitats—native prairie, planted grasslands, and wetlands—which also support nesting species like Western Grebes, Ruddy Ducks, and a host of shorebirds and songbirds.
Though less information is readily available for McKenzie Slough, it is part of the same critical Prairie Pothole landscape, offering vital wetland habitat that attracts similar concentrations of waterbirds and grassland specialties, including sought-after species like the Baird's Sparrow, Sprague's Pipit, and Chestnut-collared Longspur.
Visitors can expect to see over 200 species of birds, ranging from impressive flights of American White Pelicans to the subtle beauty of grassland sparrows. These refuges and sloughs provide an accessible and unparalleled opportunity to witness the incredible biodiversity of the northern plains.
Long Lake NWR
Long Lake National Wildlife Refuge (NWR) is a crucial sanctuary situated in south-central North Dakota, primarily near the town of Moffit, and encompasses parts of Burleigh and Kidder counties. Geographically, it lies along the western edge of the Prairie Pothole Region, where the flat Coteau Slope meets the rolling terrain of the Missouri Coteau. This junction creates a complex landscape of mixed-grass prairie, scattered small wetlands, and the refuge's namesake—Long Lake.

This is an 18-mile-long, shallow, saline (salty) lake basin that has been partitioned by dikes for water level management. The lake’s depth is highly dynamic, ranging from marsh-like shallows in most years to depths of up to seven feet in wet periods, leading to a highly variable and productive aquatic system that is vital for migratory birds.
Established in 1932 along the Central Flyway, Long Lake NWR is globally recognized for its importance to avian conservation, designated as both a Globally Important Bird Area and a Western Hemisphere Shorebird Reserve Network (WHSRN) site. Birdwatching opportunities peak in spring and fall, when the refuge hosts thousands of migrating waterfowl, including massive flights of ducks, geese, and Sandhill Cranes, with occasional sightings of the endangered Whooping Crane.

During the nesting season, the expansive mudflats (especially when water levels recede) and grassy uplands attract a rich diversity of species. Notable nesters include the Marbled Godwit, Willet, and the threatened Piping Plover, while visitors in spring can witness the dramatic mating displays of Western Grebes on the open water and the 'dancing' of Sharp-tailed Grouse on traditional leks in the native prairie.

Bowman-Haley Recreation Area
The Bowman-Haley Recreation Area is situated in the southwestern corner of North Dakota, approximately 11 miles south of the city of Bowman and just a couple of miles north of the border with South Dakota. The geography of the area is defined by the Bowman-Haley Dam, an earthen dam completed in 1970 on the North Fork of the Grand River. This structure created Bowman-Haley Lake (also known as the Bowman-Haley Reservoir), a V-shaped body of water with about 17 miles of shoreline.

The surrounding landscape consists of roughly 7,000 acres of rolling uplands and prairie creeks, a classic example of the rugged buttes and mixed-grass prairie of the western Great Plains, contrasting with the central and eastern portions of the state. This geographic setting, nestled between prairie, uplands, and a substantial reservoir, creates a unique transitional habitat.
The distinct mix of open water, riparian creek bottoms, and short-grass prairie makes Bowman-Haley a crucial spot for birdwatching, especially given its location near the western edge of the Central Flyway. The reservoir attracts an abundance of waterfowl and shorebirds, including various ducks, geese, gulls, and terns, particularly during migration.

Furthermore, the surrounding mixed-grass prairie provides excellent opportunities to find signature western grassland species such as the Chestnut-collared Longspur, Lark Bunting, and possibly the elusive Baird's Sparrow or Sprague's Pipit. Birders may also spot raptors like the Prairie Falcon over the rolling landscape and occasionally even the endangered Whooping Crane during its spring and fall migration between Texas and Canada's Wood Buffalo National Park.

McKenzie Slough
McKenzie Slough, officially the McKenzie Slough Wildlife Management Area, is a highly productive wetland complex located in Burleigh County, North Dakota, just southeast of the state's capital, Bismarck. Geographically, it is part of the vast Prairie Pothole Region, a crucial landscape of the North American Great Plains formed by the last glaciation, which left behind millions of shallow depressions or "potholes" that fill with water.

The slough itself is described as a large swamp area within the Lake McKenzie Basin, an extensive lake plain surrounded by low glacial hills. Its position near the Missouri River and in the Central Flyway ensures that the 736-acre management area's diverse habitat of emergent vegetation, open water, and surrounding prairie is essential for migrating and breeding birds.
The primary appeal of McKenzie Slough for birdwatching lies in its phenomenal concentrations of waterbirds and migratory species. When water levels are high, the slough is a reliable breeding ground for a variety of nesting species, including Pied-billed and Eared Grebes, Ruddy Ducks, American Coots, and colonial nesters like Yellow-headed Blackbirds and Marsh Wrens.

During the spring and fall migrations, the slough becomes a temporary home for a stunning array of waterfowl and shorebirds such as American Avocets, Wilson's Phalaropes, and various sandpipers. Notably, the area hosts a massive blackbird mega-roost in the fall, where radar has estimated counts of hundreds of thousands to over a million birds, offering an unforgettable avian spectacle for visitors to the region.

Arrowwood NWR
Arrowwood National Wildlife Refuge (NWR) is centrally located in North Dakota, roughly 26 miles north of Jamestown, spanning parts of Stutsman and Foster counties near the town of Pingree. Established in 1935, the refuge encompasses nearly 16,000 acres, its geography defined by a 16-mile stretch of the James River Valley. This river system feeds four main water bodies—Arrowwood Lake, Mud Lake, Jim Lake, and Depuy Marsh—creating a unique, diverse blend of habitats.

While predominantly mixed-grass prairie and extensive wetlands within the Prairie Pothole Region, Arrowwood is also notable for its forested coulees featuring uncommon trees like oak and hackberry, which offer sheltered areas that contrast with the open plains. The refuge's management actively uses prescribed fire and grazing to maintain healthy native grasslands, ensuring it remains an ideal environment for both resident and migratory species.
As a critical stopover along the Central Flyway, Arrowwood NWR offers outstanding and varied birdwatching opportunities, with over 250 species documented over time. The refuge is renowned for its spectacular concentrations of waterfowl during spring and fall migrations, when numbers of ducks and geese can swell to nearly 100,000. Common sightings include Canada Geese, Mallards, Pintails, and various diving ducks.

The mixed habitats also make it excellent for observing diverse bird groups, from wading birds like Great Blue Herons and American Bitterns in the wetlands to prized grassland songbirds such as the Baird's Sparrow, Grasshopper Sparrow, and Bobolink in the uplands. Birders can take advantage of the 5.5-mile self-guided Auto Tour Route and the dedicated Warbler Woodland Watchable Wildlife Area, a great spot to catch numerous songbirds during the May spring migration.

Minot Sewage Lagoons
The Minot Sewage Lagoons are a well-known, albeit unorthodox, birdwatching hotspot located just outside the city of Minot in Ward County, North Dakota. Geographically, this location sits squarely within the state’s expansive Prairie Pothole Region, a landscape defined by thousands of small, glacier-formed wetlands and surrounding mixed-grass prairie.

While Minot itself lies in the Souris River Valley, the artificial bodies of water created by the city’s wastewater treatment process mimic the natural sloughs and wetlands of the prairie, creating a reliable and year-round source of open water and varied mudflat habitat that is often absent elsewhere, especially during dry periods or late in the season. These man-made impoundments provide a critical stopover for migratory species traversing the Central Flyway.
The dependable water and controlled water levels at the lagoons create exceptional birdwatching opportunities, particularly for waterfowl and shorebirds. Birders frequent the site to observe large congregations of ducks, geese, and grebes, including species like Gadwall, Northern Shoveler, Ruddy Duck, and multiple grebe species, such as Eared Grebe.

Crucially, the varying water depths attract a diverse array of waders and shorebirds like Wilson's Phalarope, American Avocet, Black-necked Stilt, and various sandpipers, which forage along the muddy edges of the dikes. The site’s reputation as a reliable spot for unusual migrants, including the occasional rarity, makes it an essential stop for any birder visiting the Minot area, supplementing the excellent birding found at nearby natural areas like the Upper Souris and Des Lacs National Wildlife Refuges.

Kellys Slough NWR
Kellys Slough National Wildlife Refuge (NWR) is strategically located in the heart of the agriculturally intensive Red River Valley in Grand Forks County, northeastern North Dakota, approximately 11 miles west of the city of Grand Forks. Geographically, the refuge lies within the ancient lakebed of Glacial Lake Agassiz, resulting in a smooth, nearly level topography. This location is part of the famed Prairie Pothole Region, a critical ecosystem of the U.S. Central Flyway. The refuge complex, established in 1936, encompasses a system of managed wetlands and grasslands, covering about 1,270 acres.

The intermittent stream of Kellys Slough, which flows into the Turtle River, forms the core wetland habitat. This system is crucial because it serves as one of the few significant wetland stopover points in the intensively farmed Red River Valley, providing essential water and rest for countless migratory birds.
The refuge's location and actively managed wetlands—including eight water-controlled pools—make it an exceptional birdwatching destination, particularly for shorebirds and waterfowl. Kellys Slough NWR has been designated as a Western Hemisphere Shorebird Reserve Network (WHSRN) Site of Regional Importance, hosting over 35,000 shorebirds between April and August. Birders can regularly spot over 22 species of shorebirds during peak migration, including the American Avocet, Wilson's Phalarope, Lesser Yellowlegs, and Marbled Godwit.

Additionally, the managed pools and surrounding grasslands provide nesting habitat for a wide variety of species: over a dozen species of ducks, such as Mallards and Blue-winged Teal, along with grassland birds like Bobolinks and various sparrows. An elevated viewing platform and short nature trails offer excellent, accessible vantage points for observing these spectacular concentrations of migrating and breeding waterbirds.
