Two miles up, the crumbling precipices seem devoid of life.
兩英里高的碎石崖上似乎不可能有生命存在
But there are animals here. A grizzly bear.
可是那里仍有動物。一只灰熊
It seems to be an odd creature to find on these high rocky slopes.
很奇怪這樣的動物為何會爬到如此高的碎石斜坡上
It's hard to imagine what could have attracted it here.
真不知道這里有什么吸引著它
At this time of the year, bears should be fattening up for the winter,
在每年的這個時候，熊必須為越冬儲備脂肪
yet they gather in some numbers on these apparently barren slopes.
然而卻有一定數量的灰熊聚集在這片不毛之地
They're searching for a rather unusual food. Moths.
它們正在尋找一種很特別的食物。飛蛾
Millions have flown up here to escape the heat of the lowlands and they're now roosting among the rocks.
為了躲避低洼地帶的炎熱，數百萬只飛蛾抵達此地，棲身于巖石縫隙之中
Moths may seem a meagre meal for a bear,
飛蛾似乎并不足以填飽熊的肚子
but their bodies are rich in fat and can make all the difference in a bear's annual struggle for survival.
但它們身體內富含脂肪，直接關系到灰熊每年冬天的生存能力。
