DietThe snow goose is an herbivore. It feeds in water-logged soil or shallow water and eats a variety of plant species and parts, from aquatic plants to grasses and grain. Some of their favorite foods include grasses, sedges, willows, rushes, and horsetails. Snow geese will eat all parts of a plant from seeds, leaves, and stems to tubers and roots. They graze for seeds and grain above the ground and also grub around and rip up plants by the roots. In the winter, they feed on left over grain and new shoots on farmland. The snow goose is a voracious eater. They have to be, food passes though their digestive system in only an hour or two! Life CycleSnow goose pairs form in the spring and nest in colonies. The female lays 2-5 white eggs in a scrape in the ground lined with dried plant parts and down. The male guards the nest while the female incubates the eggs. The gosling hatch in 22-25 days. The goslings leave the nest within two days of hatching and can swim and feed themselves. The goslings stay with their parents through the first winter and migrate with them in the fall and then again in the spring back to the breeding grounds. Male and female pairs usually mate for life. Behavior
Snow geese migrate in large flocks and fly during both night and day. They rest and feed on marshes and other wetlands during their migration. They usually return to the same nesting area each year. |
