When do snow geese begin to arrive in SW Iowa?
The geese start to move into SW Iowa when the ground is snow free and they have open water to roost at night. That may be as early as mid February or as late as mid March. Snow geese migrate during warm fronts with a south wind. If the ground is snow free but water areas are still frozen some birds may move into Iowa during the daytime but fly back south at night to roost in open water.
