Other meanings of Central Flyway
Ornithology
The Central Flyway is one of the four principal North American bird migration routes, spanning the Great Plains between the Mississippi River and the Rocky Mountains. It channels millions of waterfowl, shorebirds, and songbirds from their Arctic and prairie breeding grounds to wintering areas in the southern United States and Mexico. The flyway is managed cooperatively by federal and state agencies under the Migratory Bird Treaty Act, with a focus on habitat conservation and sustainable hunting.
The Central Flyway extends from the Canadian prairies and the Arctic tundra south through the Great Plains, following the Missouri and Mississippi river systems, and reaches wintering grounds in Texas, Mexico, and Central America1. It includes the eastern slopes of the Rocky Mountains and the western edge of the Mississippi River basin, covering states such as Montana, Wyoming, Colorado, Nebraska, Kansas, Oklahoma, and Texas2. The flyway's wetlands, including the Prairie Pothole Region and the Platte River, serve as critical stopover sites for migrating birds.
Waterfowl dominate the flyway, with species like the mallard, northern pintail, and snow goose relying on its wetlands for breeding and staging. Shorebirds, such as the long-billed curlew and the piping plover, also use the flyway, as do raptors like the Swainson's hawk, which migrates to Argentina3. The timing of migration is tightly linked to seasonal food availability, and climate change is altering these patterns, causing earlier arrivals and shifts in range4.
The Central Flyway Council, established in 1952, coordinates waterfowl management among state and federal agencies, setting hunting regulations and habitat priorities5. The U.S. Fish and Wildlife Service and the Canadian Wildlife Service jointly monitor populations and set harvest limits under the Migratory Bird Treaty Act6. Habitat loss, particularly of wetlands, remains the greatest threat, prompting initiatives like the Prairie Pothole Joint Venture and the North American Wetlands Conservation Act7.
The flyway is also a corridor for the endangered whooping crane, whose only wild flock migrates from Wood Buffalo National Park to Aransas National Wildlife Refuge, passing through the Central Flyway1. Historically, the flyway was a route for passenger pigeons, now extinct, and for the Eskimo curlew, likely extinct. The term 'flyway' was popularized by ornithologist Frederick Lincoln in the 1930s, who used banding data to map these routes2. The flyway also intersects with the 'Central Corridor' of the Monarch butterfly migration, though the butterflies are not birds.
The Central Flyway is one of four major North American flyways, each named for its geographic corridor.
