O ganso-de-cabeça-listrada é famoso pelas suas extraordinárias migrações de alta altitude sobre o Himalaia, atingindo elevações de mais de 7.000 metros. É facilmente identificado pelas duas listras pretas características na cabeça branca. Cria em lagos de alta altitude no Tibete, Mongólia e países adjacentes. Hiberna nas planícies do subcontinente indiano. Tem fisiologia especialmente adaptada para respirar em altitudes extremas com hemoglobina que tem maior afinidade pelo oxigénio.
