Sobre

O ganso-cisne é um grande ganso do leste da Ásia com um pescoço longo e bico com tubérculo proeminente na base. É o ancestral dos gansos domésticos do leste da Ásia, incluindo o ganso chinês. Em estado selvagem, cria em zonas húmidas de floresta e pradaria na Rússia Oriental, Mongólia e China. Hiberna na China, Japão e Coreia. As populações selvagens são ameaçadas e têm sofrido declínios significativos devido à perda de habitat de hibernação e caça.
