馴鹿 秋季遷徙時(shí)正在游過(guò)科伯克河的馴鹿 每年秋天，25萬(wàn)頭馴鹿聚集在一起組成了北極西部馴鹿群，這群馴鹿在阿拉斯加西北部進(jìn)行了史詩(shī)般的遷徙。它們從烏圖克河高地的產(chǎn)犢地向南遷移到蘇厄德半島的冬季牧場(chǎng)。秋天也是科學(xué)家們給牛群成員系上無(wú)線電項(xiàng)圈，追蹤它們的位置和健康狀況，并獲得有助于保護(hù)該物種的信息的時(shí)候。當(dāng)春天到來(lái)時(shí)，他們將再次以相反的方式完成旅行，每年總共行駛2000英里拿著。一個(gè)觀察牛群遷徙的最佳地點(diǎn)之一是在洋蔥波蒂奇，成群的動(dòng)物穿過(guò)這條河，科布克河。這個(gè)名字來(lái)源于因紐特人（Inupiaq，因紐特人），意思是“野洋蔥”，意思是這里生長(zhǎng)的許多野洋蔥。但是當(dāng)?shù)匾蚣~特人來(lái)這里不僅僅是為了尋找洋蔥。幾千年來(lái)，馴鹿穿越吸引了依賴馴鹿肉的原住民，這一傳統(tǒng)一直延續(xù)至今。

原文:

Each fall a quarter million caribou come together to form the Western Arctic Caribou Herd, a group that makes an epic migration through northwest Alaska. In great numbers they move south from their calving grounds in the Utukok River Uplands to their winter range on the Seward Peninsula. Fall is also the time when scientists attach radio collars to members of the herd, to track their location and health, and to gain information that will help conserve the species. When spring arrives, they'll complete the trip again in reverse, covering a total of 2,000 miles each year, give or take.One of the best spots to see the herd on the move is where the great masses of animals cross this river, the Kobuk, at Onion Portage. The name of the portage derives from an Inupiaq (Inuit) word meaning 'wild onions' for the many wild onions that grow here. But the native Inuit people don't come here just to forage for onions. For millennia, the caribou crossing has drawn native peoples who rely on caribou meat, a tradition that continues to this day.
