Each fall, millions of geese, ducks, hawks, and cranes start a long migration from northern North America, heading for warmer locations in the South. A few months later, large numbers of human migrants from Canada and from the northern tier of American states prepare for their escape from the rigors of snow shoveling, sub-zero temperatures, and dark winter nights. Packing their golf clubs, swimming trunks, and suntan oil, they travel by car, recreational vehicle, and airplane to the southern United States and Mexico. These seasonal migrants are often called "snowbirds."
