Snow Geese breed in the Arctic Tundra and winter in farmlands, lakes and coastal areas in the American south, southwest and east coast. These attractive geese occur only in North America, and make an annual round trip journey of more than 5,000 miles at speeds of 50 mph or more.
Temperatures plunge well below zero, fresh water and plants are often scarce and in some places the sun doesn't even rise to light and warm the Earth for extended periods. While humans couldn't survive outdoors for long in, say, the Arctic tundra, diverse types of animals have adapted to live there and in other cold climates successfully. Migration Some animals live in cold places for part of the year, but migrate to a slightly warmer and more hospitable environment when winter rolls around. Many types of birds, including various species of geese, ducks and cranes, fly south for the winter.
