Like a blizzard filling the sky, these pictures show one of nature's most amazing displays as more than a million snow geese stop for a rest during their annual migration.

The spectacular shots were taken by Mike Hollingshead in Squaw Creek National Wildlife Refuge near Mound City, Missouri. The geese must travel 2,500miles twice a year.

Every autumn the snow geese head from their main breeding grounds in central Canada to their wintering grounds in the Gulf of Mexico. The noisy birds migrate in unusually large flocks of 100 to 1,000 that are made up of many family groups. Biologists still do not understand how the birds decide when to migrate.
