Minnesota Important Bird Areas

Essential habitats for birds

Minnesota's IBAs

Important Bird Areas (IBAs) provide essential habitat for one or more breeding, wintering, and/or migrating bird species. The IBA program is designed to be proactive, voluntary, participatory, science-based and works to identify, monitor and conserve the most essential habitats for birds. Read more about how we determine Minnesota's IBAs and how we use them to prioritize our work.

Agassiz National Wildlife Refuge IBA Bird List

Situated in the transition zone between the tallgrass prairie and prairie pothole region in northwestern Minnesota, 40,000 ducks and 14,000 geese use this IBA during migration. The largest Franklin’s Gull colony in Minnesota and one of the largest in North America, along with Black Terns, Eared Grebes and other waterbirds nest here.

Arden Hills Army Training Site - Rice Creek IBA |Bird List

Located in north-central Ramsey County is a natural area of nearly 2,000 acres in an urban landscape supporting 66 bird species. It consists of two parts: the Ramsey County Open Space known as Rice Creek North and the Arden Hills Army Training Site (AHATS). It has important habitat for waterfowl, raptors, and passerines all within an urban area, offers a unique opportunity for birders and others to view wildlife in the Twin Cities. Trumpeter Swans with their young have been observed repeatedly and a small number of Forster’s Terns and Red-shouldered Hawks have been seen.

Species common to both the northern and southern part of the state are found here including Red-shouldered Hawks, Cerulean Warblers, and Blue-winged Warblers.

Big Bog IBA |Bird List

The Big Bog IBA, over 1.7 million acres in size is in habitat generally known as the Red Lake Peatlands, and contains some of the most unique terrain and habitat in the United States. It is a vast, forested, boreal landscape at latitude where elsewhere in the eastern forest in the US, boreal forest is uncommon. The area is located in north central Minnesota north and east of the Red Lake Reservoir. This IBA includes land within the Red Lake Indian Reservation along with a number of state owned Wildlife Management Areas, Scientific and Natural Areas and State Forests and Parks. At least 289 bird species are found in this area, including at least 12 species of breeding warblers. At least 110 species are major users of this habitat. Numbers alone do not convey the unique diversity of species found in this transitional zone between prairie, deciduous forest, and northern boreal forest. Boreal forest species such as Spruce Grouse, Boreal Chickadee, Black-backed and Three-toed Woodpeckers and many species of neo-tropical warblers occur and breed in this area. The site is a major concentration point for Northern Hawk Owls and Great Gray Owls during the period November to March. The fact that some mammals and many bird species are at the southern edge of their distributional range in this IBA confers even more ecological significance to this area.

This IBA contains a very diverse number of habitats including; prairie grasslands (both virgin and restored), floodplain deciduous forests and their riparian habitats, a wide variety of marshes, several very large lakes plus numerous smaller bodies of water such as prairie potholes. This has resulted in a rich diversity of species including some of Minnesota’s largest concentrations of Canada Geese and other waterfowl, the world’s largest American White Pelican breeding colony (2006) along with other waterbirds, shorebirds and grassland songbirds. This diverse wildlife habitat is surrounded by some of the best, and as a result, the most intensely farmed areas in the upper Midwest. The area is recognized as one of the top ranked birding areas in the State of Minnesota and also attracts waterfowl and upland game hunters and other outdoor recreation users.

Lake Byllesby IBA |Bird List

Lake Byllesby lies in the Cannon River Valley located about 30 miles due south of downtown St. Paul. As birds migrate northward in the spring via the Mississippi River corridor, many eventually leave the corridor and head northwest across southeast Minnesota to follow the prairie-hardwood transition zone enroute to their breeding grounds to the north. The relatively large size of Lake Byllesby with its associated extensive mudflats and shallow areas provide important resting and feeding habitat that is in very short supply in this region of the state. The site contains an assemblage of species characteristic of shallow wetland and alluvial mudflat habitat type. This includes: 31 (78%) of Minnesota's 40 recorded shorebird species; 30 (70%) of Minnesota's 43 recorded waterfowl species; Common, Forster's, Caspian, and Black Tern; American White Pelican, and others.

Lake Osakis is one of Minnesota's most famous birding lakes, supporting major breeding populations of several important nongame bird species that are not well represented elsewhere in the state. It has the largest breeding population of western grebes in the state. Red-necked grebes and a few Clark's grebes have also been documented. Historically, one of Minnesota's largest colonies of Forster's terns a species of special concern in the state, was also documented at Lake Osakis.

Lake of the Woods IBA |Bird List

Lake of the Woods is the largest lake in Minnesota, although most of the lake is in Canada. The areas included within the IBA are the entire lake (United State portion), all the islands (approximately 25 in number), and the open wetlands (sedge, cattails, etc) immediately adjoining the lake. All of Zippel Bay State Park, Garden Island State Recreation Area, Pine and Curry Island Scientific and Natural Area, and Larry Bernhoft, Rocky Point, South Shore, and Border Wildlife Management Areas are included in the IBA. Parts of the Canadian side of the lake have been identified as an Important Bird Area (ON 144). Lake of the Woods is a large body of water attracting migrating waterfowl in both spring and fall. Historically tens of thousands of Lesser and Greater Scaup have migrated through the area. Lesser numbers of teal, American Widgeon, Pintails, and mergansers can also be observed during periods of migration with some local nesting. In recent years, the numbers of Canada Geese have been on the increase. Numerous raptors can be observed along the shores of Lake of the Woods as they skirt the large lake and travel along mainland corridors Pine and Curry Islands, Garden Island and the sandy beaches of the Northwest Angle may be the last areas where the Piping Plover can find adequate breeding localities in the state. Garden Island, with its large sandbars and beaches is a major stop over spot for many migrating shorebirds.
