斑头雁

放牧和旅游是斑头雁与人接触的主要原因。青海湖斑头雁和人的接触强度在空间和时间上均差异显著。

Livestock grazing and tourism were the major reasons resulting in contact between Bar-headed Goose and human .

相反地，斑头雁却是依靠奋力扇动翅膀飞到如此高度的，虽然其姿态并不怎么优雅。

By contrast , the bar-headed goose reaches such lofty heights by flapping vigorously , if not gracefully .

斑头雁与其它飞禽相比，它们用于飞行的肌肉里有更多的线粒体&这是一种能在细胞内产生能量的结构。

The geese 's flight muscles also have more mitochondria energy-producing structures inside cells than their fellow fowl .

与人类不同的是，斑头雁可以急速呼吸而不会头晕或者昏倒。

Unlike humans , bar-headed geese can breathe in and out very rapidly without getting dizzy or passing out .

更令人惊奇的是，这些斑头雁在上升过程中仅仅凭借它们自己肌肉的力量，而并未借助顺风或上升的气流。

Even more impressive , the birds completed the ascent under their own muscular power , with almost no aid from tail winds or updrafts .

结果表明：斑头雁通常是早上730后飞离夜栖地，傍晚1930以后从主要活动地飞回夜栖地。

The results showed that Anser indicus usually flied away from the roosting area at 7:30 am , and came back from the main activity area at 7:30 pm .

这些斑头雁可以选择向东、向西或者绕过这座山脉，而不用飞越，但是这可能会增加几天的行程，可能会消耗更多的体力。

The birds could potentially head east or west and fly around , rather than over , the mountain range , but this would add several days to their trip and would actually use up more energy .

2005年以来，斑头雁在多起高致病性禽流感疫情中大量死亡，其生物生态学以及在禽流感病毒扩散中的作用引起关注。

Since 2005 , the species had been involved in a number of HPAI outbreaks and resulted in mass death , which draw widely concern on its biology , ecology and the role in spread of avian influenza virus .
