hummingbird

In a presumably posthumous voiceover, Bwana Beast says he would do it all again, in a hummingbird's heartbeat.

在大概是死后的画外音里，比斯特说他愿意再来一次，不过这次是以蜂鸟的心跳。

Implanted sensors show that a hummingbird’s wing flaps so fast that the brain is generating the muscle signal for the downbeat of its wing while the wing is still going up.

植入的传感器表明，蜂鸟翅膀击打的速度如此之快，以至于当其脑部发出的肌肉信号命令翅膀向下挥动时，但翅膀还是向上挥。

The smaller the bird, for example, the more agile the flying — a swan may need the equivalent of two football fields to take off and get lift, while a hummingbird can rise like a helicopter.

例如，鸟类的体型越小，飞行动作就越灵敏——天鹅就需要两个足球场大的面积才能完成起飞和抬升动作，而蜂鸟就可以像直升机一样垂直起飞。
