The call of the wild in Alaska

Most visitors to Denali National Park and Preserve in Alaska come with a checklist for the 'big five' mammals that live here: Grizzly bears, moose, wolves, Dall sheep, and caribou like this small group walking along a ridge. These are barren-ground caribou, a migratory subspecies of caribou found across the arctic band of North America to western Greenland. Barren-ground caribou migrate in large herds, some traveling over 600 miles one way, between their summer and winter ranges. But the Denali herd, today which numbers around 3,000 animals, generally stay on the park's 6 million acres. For good reason, too—they're the only large herd that aren't hunted.

阿拉斯加野性的呼唤

大多数到德纳利国家公园和阿拉斯加自然保护区的游客都会带上一份居住在这里的“五大”哺乳动物的清单：灰熊、驼鹿、狼、大头羊和驯鹿，就像这一小群沿着山脊行走的动物一样。这些是贫瘠的地面驯鹿，驯鹿的一个迁徙亚种，发现于北美洲北极带到格陵兰岛西部。贫瘠的地面驯鹿成群结队地迁徙，有些驯鹿在夏季和冬季之间单程旅行600英里。但如今的德纳利兽群大约有3000头，它们一般都生活在公园的600万英亩土地上。也有很好的理由，它们是唯一没有被猎杀的大型兽群。
