The swan goose is a large, long-necked goose with a dark crown and hindneck sharply contrasting with its pale face and fore-neck. It breeds around lakes, marshes and river valleys in Mongolia, northern China and south-eastern Russia, migrating mainly to eastern China. Flocks graze grasses and sedges and pull aquatic plants; the domestic Chinese goose descends from this species (Wikipedia, general species account). It is Nationally Vulnerable (Thailand Red Data 2025).
