During migration, water birds rely on a system of highly productive wetlands to rest and feed, building up sufficient energy to fuel the next phase of their journey. International cooperation across their migratory range is therefore essential to conserve and protect migratory water birds and the habitats on which they depend. [ 2 ]
The passing of the Migratory Bird Treaty Act of 1918 in the United States resulted in a need for more information on bird migration. Frederick Charles Lincoln was put in charge and improved methods for trapping and banding, developed record-keeping procedures, recruited banders, fostered international cooperation, and promoted banding as a tool for research and wildlife management.

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.

A common pattern in North America is clockwise migration, where birds flying North tend to be further West, and flying South tend to shift Eastwards. Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V formation may conserve 12–20% of the energy they would need to fly alone.
Milwaukee is under "high" migration alert Wednesday night, with more than 27,000 birds expected to migrate over the city. Kakatsch said colder weather usually drives an upswing in migration in the ...
