The Mississippi Flyway is a bird migration route that generally follows the Mississippi, Missouri, and Lower Ohio Rivers in the United States across the western Great Lakes to the Mackenzie River and Hudson Bay in Canada. The main endpoints of the flyway include central Canada and the region surrounding the Gulf of Mexico. [1] The migration route tends to narrow considerably in the lower Mississippi River valley in the states of Missouri, Arkansas, Mississippi, and Louisiana, which accounts for the high number of bird species found in those areas. [2] Some birds use this flyway to migrate from the Arctic Ocean to Patagonia. [3]
Typically birds use this route because no mountains or ridges of hills block the path over its entire extent. [2] Good sources of water, food, and cover exist over its entire length. About 40% of all North American migrating waterfowl and shorebirds use this route. [3]
The other primary migration routes for North American birds include the Atlantic, Central and Pacific Flyways. The Central Flyway merges with the Mississippi Flyway between Missouri and the Gulf of Mexico. In the northern portions of the Upper Mississippi River, the birds congregate in the Driftless Area. [4]
Major wildlife refuges along the flyway include Trempealeau National Wildlife Refuge and Upper Mississippi River National Wildlife and Fish Refuge. [5]
A flyway is a flight path used by large numbers of birds while migrating between their breeding grounds and their overwintering quarters. Flyways generally span continents and often pass over oceans. Although applying to any species of migrating bird, the concept was first conceived and applied to waterfowl and shore birds. The flyways can be thought of as wide arterial highways to which the migratory routes of different species are tributaries. An alternative definition is that a flyway is the entire range of a migratory bird, encompassing both its breeding and non-breeding grounds, and the resting and feeding locations it uses while migrating. There are four major north–south flyways in North America and six covering Eurasia, Africa, and Australasia.
The Central Flyway is a bird migration route that generally follows the Great Plains in the United States and Canada. The main endpoints of the flyway include the Canadian Prairies and the region surrounding the Gulf of Mexico; the migration route tends to narrow considerably in the Platte River and Missouri River valleys of central and eastern Nebraska, which accounts for the high number of bird species found there. Some birds even use this flyway to migrate from the Arctic Ocean to Patagonia. Routes used by birds are typically established because no mountains or large hills block the flyway over its entire extent. Good sources of water, food, and cover exist over its entire length.
DeSoto National Wildlife Refuge, created in 1958, is located along the banks of the Missouri River in the U.S. states of Iowa and Nebraska. The 8,362-acre (3,384 ha) refuge preserves an area that would have been otherwise lost to cultivation. In 1960, an Army Corps of Engineers channelization project on the Missouri River moved the main river channel in the area to the west. The former river channel became DeSoto Lake, a seven-mile long oxbow lake. As a result, part of the Nebraska portion of the refuge lies on the east side of the Missouri River.
The Upper Mississippi River is today the portion of the Mississippi River upstream of St. Louis, Missouri, United States, at the confluence of its main tributary, the Missouri River. Historically, it may refer to the area above the Arkansas Post, above the confluence of Ohio River, or above Cape Girardeau.
The Cape May National Wildlife Refuge is a protected area on the Cape May Peninsula in Cape May County, New Jersey. It is part of the National Wildlife Refuge System and managed by the United States Fish and Wildlife Service. Established in January 1989 with 90 acres (0.36 km2) acquired from the Nature Conservancy, it has since grown to more than 11,000 acres (45 km2) in size, and plans call for its further expansion to more than 21,200 acres (86 km2). It comprises three distinct and non-contiguous units: the Delaware Bay Division, the Great Cedar Swamp Division and the Two Mile Beach Unit. Located in the Middle Atlantic coastal forests ecoregion, the cape provides habitat for large numbers of migratory birds.
The Mark Twain National Wildlife Refuge Complex was established for the protection of migratory birds including waterfowl, shorebirds, and songbirds. It is located along the Mississippi Flyway, one of the major routes for migrating waterfowl. Refuge units also provide important habitat for big-river fish and a variety of other native wildlife such as deer, fox, beaver, frogs, turtles, and snakes. Key goals are to conserve and enhance the quality and diversity of fish and wildlife and their habitats, to restore floodplain functions in the river corridor, and to provide wildlife-related recreational experiences for the public.
The Mingo National Wildlife Refuge is a 21,676-acre (87.7-km2) National Wildlife Refuge located in northwestern Stoddard and southeastern Wayne counties in Missouri. Its southwesternmost portion lies on the shores of Lake Wappapello. Named after the Mingo tribe, it was established to preserve bottomland hardwoods and provide waterfowl and other migratory birds in the Mississippi Flyway with nesting, feeding, brooding, and resting habitat.
The Atlantic Flyway is a major north-south flyway for migratory birds in North America. The route generally starts in Greenland, then follows the Atlantic coast of Canada, then south down the Atlantic Coast of the United States to the tropical areas of South America and the Caribbean. Every year, migratory birds travel up and down this route following food sources, heading to breeding grounds, or traveling to overwintering sites.
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites.
The Deer Flat National Wildlife Refuge is an important breeding area for mammals, birds, and other animals. The National Wildlife Refuge is located on land surrounding Lake Lowell, just outside Nampa, Idaho. It serves as a resting and wintering area for birds, including mallards and Canada geese, along the Pacific Flyway and was named a "Globally Important Bird Area" by the American Bird Conservancy.
Port Louisa National Wildlife Refuge is a 10,780-acre (43.6 km2) National Wildlife Refuge located on the Mississippi River at the border of Illinois and Iowa. The refuge is east of Wapello, in Louisa County, Iowa and Mercer County, Illinois.
Trempealeau National Wildlife Refuge is a 6,808-acre (27.55 km2) National Wildlife Refuge located along the Upper Mississippi River in extreme southern Buffalo County and extreme southwestern Trempealeau County in Wisconsin, United States. There are two small private areas in the protected area.
The Missouri River Valley outlines the journey of the Missouri River from its headwaters where the Madison, Jefferson and Gallatin Rivers flow together in Montana to its confluence with the Mississippi River in the State of Missouri. At 2,300 miles (3,700 km) long the valley drains one-sixth of the United States, and is the longest river valley on the North American continent. The valley in the Missouri River basin includes river bottoms and floodplains.
The North American Waterfowl Management Plan (NAWMP) is an international plan to conserve waterfowl and migratory birds in North America. It was established in 1986 by Canada and the United States, and expanded to include Mexico in 1994.
Lake Ophelia National Wildlife Refuge was established in 1988 to protect the Mississippi/Red River floodplain ecosystem. The refuge is located in Avoyelles Parish, Louisiana, east central Louisiana. The refuge is named for its most prominent water body, the 350-acre (1.4 km2) Lake Ophelia that was at one time a channel of the nearby Red River of the South.
Hagerman National Wildlife Refuge (HNWR), a haven for migratory birds and other wildlife, lies in northwestern Grayson County, Texas, on the Big Mineral Arm of Lake Texoma, on the Red River between Oklahoma and Texas. This National Wildlife Refuge is made up of water, marsh, and upland habitat. Visitors can hike, observe wildlife, hunt, and fish throughout the year.
The Great Texas Coastal Birding Trail is a state-designated system of trails, bird sanctuaries, and nature preserves along the entire length of the Texas Gulf Coast in the United States. As the state of Texas hosts more bird species than any other state in the U.S. the trail system offers some of the most unusual opportunities for bird-watching in the world. The "trail" is actually 43 separate hiking and driving trails that include 308 birding sites. The sites themselves feature a variety of viewing opportunities with boardwalks, observation decks, and other amenities. The trails boast more than 450 bird species. The trail system is managed by the Texas Parks and Wildlife Department as part of the Great Texas Wildlife Trails which also include the Heart of Texas Wildlife Trail, the Panhandle Plains Wildlife Trail, and the Prairies and Pineywoods Wildlife Trail.
Pass a Loutre Wildlife Management Area (WMA) is a 115,000-acre (47,000 ha) protected wetland in Plaquemines Parish, Louisiana, United States. The WMA is located due south and bordering the 48,000 acre Delta National Wildlife Refuge, accessible only by air or boat, contains the Pass A L'Outre Lighthouse, and Port Eads is within the boundary.
The Summer Lake Wildlife Area is a 29.6-square-mile (77 km2) wildlife refuge located on the northwestern edge of the Great Basin drainage in south-central Oregon. It is administered by the Oregon Department of Fish and Wildlife. The refuge is an important stop for waterfowl traveling along the Pacific Flyway during their spring and fall migrations. The Summer Lake Wildlife Area also provides habitat for shorebirds and other bird species as well as wide variety of mammals and several fish species. The Ana River supplies the water for the refuge wetlands.
The Arctic Goose Joint Venture (AGJV) is a conservation partnership established in 1989 between governments, organizations, and conservation groups to coordinate research and monitoring of Arctic, sub-Arctic and boreal nesting goose populations of North America, specifically the cackling goose, Canada goose, emperor goose, greater white-fronted goose, Ross's goose, and snow goose. Executing Arctic research expeditions in collaboration with partners is a primary goal of the venture, so that the logistics of such research can be coordinated efficiently. One of its main activities is to collar geese in Canada, the United States, and other nearby Arctic areas, such as Wrangel Island of Russia.
