Flyways of North America

 The map with green is considered the administrative boundaries of the pacific flyways.  These flyways enable biologists to monitor populations based on these migratory paths. There are four flyways in North America that run all the way into South America. The map below the green map is the "biological flyways" it is where the waterfowl actually migrate, as can be observed, these migration paths cross. These areas are broken up into councils between the four flyways to ensure that regional management is in effect.
Atlantic Flyway This includes parts of Canada, Puerto Rico and the U.S. Virgin Islands, illustrated by the black dots on the map.
Mississippi Flyway This includes parts of Canada and is shown by the blue on the biological map. This council was created in 1952 from a variety of agencies. (tribes, universities, states, conservation organizations)
Central Flyway This includes parts of Canada and Mexico, shown by the green dots.
Pacific Flyway This includes parts of Canada and Mexico, illustrated by the red dots.
All of these flyway councils recommend management suggestions for the United States Fish and Wildlife to better regulate the species.
Flyways.us is a program established for waterfowl hunting management across the North American continent. This means they collaborate with Canada to better the flyways, conducting surveys through flying over large areas and counting the amount of ducks. These are the people that give the estimates on the population numbers of the waterfowl. From these estimates, we are able to use adaptive management to adjust the harvest regulations.
