reflect the bat's clicks so effectively... they're unmistakable.
同时也令蝙蝠无法抗拒
And irresistible.
这种蝙蝠几乎可以把油麻藤 和其他任何植物区分开来
The bat can detect Mucuna more easily than almost any other plant here,
也可以得到十倍更多的花蜜
it also scores ten times more nectar,

极度需要在求偶仪式中获得关注

And right now, he's just not doing it for her.
它必须沾染上人类血液的甜香
He only gets to mate
才能获得交♥配♥权
if he's wearing a sweet perfume of human blood.
但它的毒牙并不适合噬咬人类
But his fangs aren't made for human flesh.
所以它需要其他吸血类动物 来帮它完成这个麻烦事

凭借超级灵敏的触须 它可以找到我们呼出的二氧化碳

因为它摄入血液越多
Because the more he drinks...
闻起来就越性感
the sexier he smells.
现在
Now,
他准备好开始浪漫恋情了
he's ready for romance.
身上每个毛孔都散发着血液的甜香
And with the sweet scent of blood oozing from every pore...
谁能抗拒得了呢？

要多加小心 因为不然的话… 就要开战了
because the alternative... is to fight.
体积较大的雄性♥交♥战时
When large males clash,
会有严重受伤的风险
they risk serious injury.
战斗会持续20分钟之久
Battles can last up to 20 minutes...
通常会以一方释放墨水 仓皇逃走而结束
and usually end when one escapes in a cloud of ink...

he gets away with it.
雌性非常清楚 这个鬼鬼祟祟的小东西想要干什么
The female knows exactly what the sneaky little faker is up to.
它很喜欢这样
And she likes it.
实际上 偷偷靠近的雄性 在交♥配♥方面要比体型比它大的
In fact, sneaky males are more successful at mating
对手成功率更高
than their larger rivals.
等到大块头意识到时 已经太迟了
By the time the big guy realizes, it's too late.

but this Pacific silver fir
有着非凡的特点 它是公熊的热点之地

一百多年来 它们总会来到这里
They've been visiting it for more than 100 years.
摩擦它们背部
Rubbing glands in their back,
和前面的腺体
their front,
还有它们的爪子
and their feet.
它们会留下秘密的气味信息
They leave behind secret scent messages
透露出它们的年龄、身材 以及婚姻状况
about their age, fitness, and social status.
因为这种气味会被粘稠的树脂吸收
And because the fragrance gets trapped in sticky sap,
它会在长达一个月的时间里 慢慢地挥发到空气中
it slowly diffuses into the atmosphere for up to a month.
公熊通常是用摩擦树干的方法 来建立自己的领地
Male bears regularly use the rubbing tree to establish hierarchy.

and still no one passes. Then finally,
一只公熊出现了
a male.

As soon as he gets wind of an available female,
就决心要找到它
he's determined to track her down.
凭借比猎犬还要灵敏七倍的嗅觉
And with a sense of smell seven times more sensitive than a bloodhound's,
它跟随着母熊充满诱惑的气味
he follows her alluring scent,
一路走到河滩上
all the way to the beach.
它来得正及时
He's only just in time,
但至少它们已经知道彼此相互吸引
