First the plural of "Goose" is "Geese".
Geese "migrate", that is they fly North into the Arctic regions in Spring and South to temperate regions in Autumn.
They do this because during the Arctic Summer, the Arctic wetlands are warmed by 24 hours of sunlight, the plants grow and the wetlands team with life that is food for the geese (also there are few predators).
They therefore bread in the Arctic and raise their young over these summer months.
Come Autumn/Winter the ground freezes over and snow covers the vegetation and food ceases to be available for the Geese.
They therefore fly South for the Winter to more temperate climate regions where food is available.

snow leopards do not migrate or hibernate
Yes, the northern part of the snow goose's winter range is in southern New Mexico. They also migrate through the state in the spring and fall migration; they may or may not stop during this journey. Other bands of snow geese winter in other parts of the U.S. and further south but migrate through separate flyways. See : http://identify.whatbird.com/img/4/2808/image.aspx for a range map.

Snow geese have adapted to survive in cold environments by growing thick, insulating feathers that help them stay warm. Their long necks and legs allow them to forage for food in deep snow, while their wide and powerful wings enable them to migrate long distances. They also have a keen sense of direction and are able to navigate accurately during their annual migrations.
"The Snow Goose" was written by Paul Gallico. It is a short novella that tells the tale of a crippled artist and a young girl who together help a snow goose during the Dunkirk evacuation in World War II.
