Habitat and Geographical Distribution: Migratory species. Breeding grounds include rivers and lakes abundant in reeds on the steppes of Mongolia, northern China and Russia. In winter, they are found in coastal habitats such as estuaries in western China.
Diet: Omnivore. Sedges, berries, plants, larvae and insect pupae, small fish and invertebrates.
Reproduction: Oviparous. Build nests from reeds and grasses. In some places, they reproduce in colonies. Lay 3-9 eggs that are incubated for about 28 days.
Behaviour: Can travel 2500 to 3000 km for each migration. To withstand the colder seasons, the geese tend to gather, reaching flocks of up to 30000 individuals. They feed more in the winter in order to prepare for the following breeding season.
