Typically the Canada goose engages in two seasonal migrations, each autumn and spring. According to the Ducks Unlimited website, the migration of the Canada goose is typically associated with a need for food. Grass has become a goose's primary food source and as the grasslands of the north freeze, geese travel south to more temperate climates. In the spring, geese travel along the same routes to return home to their starting point. Some Canada geese, known as resident geese, only migrate short distances unless severe weather forces them to leave, according to the Humane Society. Many geese find rest points along their migration route and may spend several days or weeks in a particular area before traveling further south, according the Wisconsin Department of Natural Resources.
