Canada Geese winter in the southern United States, and migrate north to breed in the upper Midwest, Canada, and Alaska.  Wetlands are crucial along their migratory paths.

As birds developed these migratory routes, there were natural wetlands along the way to sustain them and provide nesting grounds.  But as more humans populated and developed more and more land, many wetlands were drained and no longer available to the bird and animal species that depended upon them.  We now realize how important wetlands are for many reasons, and we are restoring and preserving them.
