Sobre

O ganso-ruivo é um pequeno ganso marinho que cria na tundra ártica e hiberna em costas marinhas temperadas. Tem cabeça e pescoço pretos com remendo branco manchado no pescoço. As subespécies variam nas cores do ventre de pálido a escuro. Alimenta-se de ervas marinhas, alfaces-do-mar e outras plantas costeiras. As populações colapsaram nos anos 1930 devido ao declínio das ervas marinhas, mas recuperaram com o retorno destas. Estão entre os gansos que percorrem as maiores distâncias de migração.
