It's the only one of its family that could live above the snow line.

这是鹦鹉家族中唯一能生活在雪线之上的品种。

Above the snow line, glacier lakes are all covered with pure white snow all year round.

雪线处，是一座座常年白雪皑皑的冰湖。

As the snow line retreats further and further up these peaks, there is less and less space for wildlife, and that is a challenge for one of the most majestic of all mountain creatures.

雪线向山峰处退去，野生动植物的生存空间日益减少，恶化的条件威胁着一种美丽山地动物的生存。

But at rare intervals warm rains and warm winds invade the mountains and push back the snow line from 2000 feet to 8000, or even higher, and then come the big floods.

但偶尔会有暖雨和暖风侵入山区，将雪线从 2000 英尺推回 8000 英尺，甚至更高，然后发生大洪水。
