Snow Geese travel in the company of another couple dozen geese and then form flocks of several hundred thousand during migration. Family groups forage together on wintering grounds, digging up tubers and roots from muddy fields and marshes. Snow Geese quickly adapt to using agricultural fields for feed which is one reason their populations have grown so much.
Snow Geese are vegetarians that eat grasses, sedges (wet-ground grass), rushes (grasslike plants with hollow stems in marshy places), shrubs, and willows. They consume seeds, stems, leaves, tubers and roots either by grazing or ripping plants out of the ground.
Food passes through their digestive tract in an hour or two, generating six to 15 droppings per hour! The rate is greatest when the goose is eating rhizomes that are high in fiber content. (Just thought you'd like to know … )

Snow Geese make epic journeys by air but they are impressive on foot, too. Within three weeks of hatching, goslings may walk as much as 50 miles with their parents to find suitable feeding areas. In wintering and migrating flocks that are feeding, lookouts keep an eye out for eagles and other predators. Upon sighting a threat, they call out and the flock takes wing.
Watching huge flocks of Snow Geese swirling down from the sky is a little like standing inside a noisy snow globe!
