After the breeding season, magpie geese move to favorable areas in large family groups and gather in large groups of several hundred when foraging. It is mainly vegetarian, mainly green plants, rushes, reeds and wild rice. Tubers and roots are also eaten on land. To do this, a wide pit is dug and the entire head and neck are buried in it.

The nesting density of magpie geese depends on location and year. Mating is possible throughout the year, with breeding beginning in the rainy season, usually October to November. The nesting takes place in two stages. The goose builds its first folded prototype nest out of vegetation and then places it in a cup-shaped nest. Male geese have two female mates, and often all three live together and remain united overall. In nature, females usually lay 7-9 eggs per nest. But if two females occupy the same nest, the number may climb to eight or 10. The incubation period is 24 to 26 days, and adult geese take turns to hatch regularly.

Listed on the International Union for Conservation of Nature (IUCN) 2012 Red List of Threatened Species ver 3.1 - Low Risk (LC).
