Last updated Waterfowl flyways in the United States. The Central Flyway is in orange
The Central Flyway is a bird migration route that generally follows the Great Plains in the United States and Canada.[1] 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.[2] 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.[3]
The other primary migration routes for North American birds includes the Atlantic, Mississippi and Pacific Flyways. The Central Flyway merges with the Mississippi Flyway between Missouri and the Gulf of Mexico.[4]
The Continental Divide of the Americas is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic and Arctic Ocean, including those that drain into the Gulf of Mexico, the Caribbean Sea, and Hudson Bay.
The Platte River is a major American river, in the state of Nebraska. It is about 310 mi (500 km) long; measured to its farthest source via its tributary, the North Platte River, it flows for over 1,050 miles (1,690 km). The Platte River is a tributary of the Missouri River, which itself is a tributary of the Mississippi River which flows to the Gulf of Mexico. The Platte over most of its length is a broad, shallow, meandering stream with a sandy bottom and many islands—a braided stream.
The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, and some Caribbean islands.
UTC−05:00 is an identifier for a time offset from UTC of −05:00. In North America, it is observed in the Eastern Time Zone during standard time, and in the Central Time Zone during the other eight months. The western Caribbean uses it year round.
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 United States is sometimes conceived as between the Eastern and Western as part of a three-region model, roughly coincident with the U.S. Census's definition of the Midwestern United States plus the western and central portions of the U.S. Census's definition of the Southern United States. The Central States are typically considered to consist of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Wisconsin, Illinois, Michigan, Indiana, Ohio, Kentucky, Tennessee, West Virginia, Mississippi and Alabama.
Triple Divide Peak is located in the Lewis Range, part of the Rocky Mountains in North America. The peak is a feature of Glacier National Park in the state of Montana in the United States. The summit of the peak, the hydrological apex of the North American continent, is the point where two of the principal continental divides in North America converge, the Continental Divide of the Americas and the Northern or Laurentian Divide.
UTC−06:00 is an identifier for a time offset from UTC of −06:00. In North America, it is observed in the Central Time Zone during standard time, and in the Mountain Time Zone during the other eight months. Several Latin American countries and a few other places use it year-round.
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. 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. Some birds use this flyway to migrate from the Arctic Ocean to Patagonia.
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 Laurentian Divide also called the Northern Divide and locally the height of land, is a continental divide in central North America that separates the Hudson Bay watershed to the north from the Gulf of Mexico watershed to the south and the Great Lakes-St. Lawrence watershed to the southeast.
Class F: Local History of the United States and British, Dutch, French, and Latin America is a classification used by the Library of Congress Classification system. This article outlines the structure of Class F classification.
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.

The 1763 Treaty of Paris ended the major war known by Americans as the French and Indian War and by Canadians as the Seven Years' War / Guerre de Sept Ans, or by French-Canadians, La Guerre de la Conquête. It was signed by Great Britain, France and Spain, with Portugal in agreement. Preferring to keep Guadeloupe, France gave up Canada and all of its claims to territory east of the Mississippi River to Britain. With France out of North America this dramatically changed the European political scene on the continent.
