虽然此时是万籁俱寂,一片荒凉的景象 - But it's about to change.
但这一切即将发生变化 - Snow geese.
雪雁 - They winter along the Gulf of Mexico, and in spring they fly the entire length of North America to reach the Arctic tundra.
它们在墨西哥湾越冬 等到春天便一路飞过北美洲 来到这里的北极苔原 - Five million birds make this journey every year.
每年有五百万只雪雁都是这样迁徙 - Their marathon migration is almost 3,000 miles long
这场马拉松式的迁徙长达三千英里 - and has taken them three months.
耗时多达三个多月
