嘿呀
Hi ya!
我是Amberly这里是Animalist News
I’m Amberly and this is Animalist News.
你可能已经看过这个视频
You guys may have seen this video
由生物学家联盟播出的
by The Company of Biologists showing a falcon
展示了一只隼攻击一只乌鸦
attacking a crow.
这真是疯狂
It is so crazy!
显然这其实是非常常见的事情
Apparently this is actually a pretty common thing
发生在大多数鸟类中 尤其是乌鸦
that happens between birds, especially crows.
为什么呢
Why?
其一 乌鸦疯狂的聪明
Well for one crows are insanely smart
它们知道集体攻击
and they know that attacking in groups
让它们对大体型的鸟类更有威慑力
makes them a lot more threatening to a larger bird,
例如隼
like a falcon.
这种聚群称为聚扰
That ganging up is called mobbing,
这可以是你现在看到的东西
and it could be what you’re seeing here.
在聚扰的情况下 比起与整个鸟群战斗
In mobbing situations, rather than fight the whole mob,
隼会孤立一只乌鸦 然后试图
falcons will single out one crow and attempt
把其他所有吓走
to scare all the others away.
正如你在视频中看到的
As you can see in the video the falcon
隼调整了它的飞行模式所以它可以跟踪同一只乌鸦
adjusts its flight pattern so it can track the same crow
在整个飞行中
throughout its entire flight.
这发生了几次 然后
It happens a couple of times, and then,
骗隼扔下炸弹
bam the falcon dive bombs.
游戏结束
Game over.
当然隼很快
Sure falcons are fast.
世界上最快的鸟是游隼
The fastest bird in the world is the peregrine falcon,
它可以达到每小时200英里的速度
and it can reach speeds over 200 miles per hour.
但是它们只能快速飞行一小段时间
But they can only go that fast for short periods of time,
所以它们需要去储存补充它们的能量。
so they need to conserve their energy.
如果一只隼错过了一次攻击
If a falcon misses an attack and instead
取而代之的是被整个乌鸦群压倒
becomes overwhelmed by the gang of crows,
它会直接撤退避免使用额外的能量
it may simply retreat and avoid using any extra energy.
如果你是一只动物 你会怎样捕到你的猎物
If you were an animal, how would you take down your prey?
让我们在下面的评论区知道
Let me know in the comments down below.
嘿 隼不是唯一一种有聪明行为的鸟
Hey, falcons aren’t the only birds that have smooth moves.
