During our spring, many of the birds using the Atlantic Flyway start at the southern tip of South America or the coast of Chile. They reach the U.S. touching Maryland, Virginia, and Delaware. From there they head to James Bay and Hudson Bay in Canada. Shorebirds have a more complicated fall migration. Most fly south to the Bay of Fundy in eastern Canada and continue to fly over the Atlantic Ocean.
Some birds choose to vear west across South America and end along the coast of Peru.
The Atlantic flyway has some interesting features to observe. Also spring and fall migration of many shorebirds are different, as the above description shows. In general, most shorebirds do not return to many of their fall stopover sights along the Atlantic coast during spring migration, aside from a few southern U.S. sites.
