The Flyway Atlas. A wider view of waterfowl.

The Flyway Atlas showing habitat layers, key sites, and generalized migration corridors across North America.

A familiar marsh is one place on a much larger map. The Flyway Atlas is a way to look beyond it, with breeding grounds, wintering grounds, staging areas, and generalized migration corridors shown together.

The map focuses on North American waterfowl and extends beyond the continent where the geography calls for it. You can explore the full view or narrow it to a species and a few layers. It is built for taking a closer look at the places and connections that are easy to miss at a single scale.

Build the view in layers.

Start with breeding grounds, wintering grounds, or staging and stopover areas. Switch layers on and off to see how each changes the map. Adding migration corridors gives you the generalized routes and staging chains; key sites add named places such as colonies, deltas, and refuges.

The species filter helps narrow the view. Clear it to return to all species. When the map becomes crowded, turn off a layer and work with one question at a time: which regions are shown, where a named site sits, or how a corridor connects the places along it.

Read the boundaries.

The atlas uses published conservation boundaries. Its ecological regions draw on NABCI Bird Conservation Regions, with selected areas represented by North American Waterfowl Management Plan Joint Venture boundaries. The administrative flyway layer uses the four U.S. Fish and Wildlife Service waterfowl flyways.

Those layers describe different kinds of geography. A conservation region and an administrative flyway serve different purposes, even when they overlap on the screen. Neither should be read as a hunting-zone boundary. The map's source notes identify the published datasets behind the outlines.

Follow a corridor with context.

The migration corridors are generalized representations of routes and staging chains. They are not live tracking, and they do not trace the exact path of an individual bird. Use them to explore the broad connections shown by the atlas.

Region labels, rivers and lakes, and state and province lines can help you place those connections. The base geography comes from Natural Earth. Optional NASA Blue Marble imagery adds shaded relief; it is a background view of the landscape, not current satellite conditions.

Move between scales.

Pan to a region, zoom in to read the local geography, and use Reset when you want the wider view again. Try the same place with different layers visible. A sparse map is often easier to read than every available layer at once.

If your next step is planning a hunt, the waterfowl regulations reference links to state summaries and official agencies. The atlas provides geographic context; current hunting rules need their own check.
