如果你正在南美洲幽静的山林里旅行,就会看见一颗颗似流星的东西飞快地掠过花丛,当你正想看清是什么东西时,它却一闪就不见了。有时,你还会看见一种奇异的“昆虫”,它的身子悬在空中,发出“嘤嘤”的声音,用长长的嘴吮吸着花蜜,你正想仔细看它时,一眨眼,它又不见了。这究竟是什么东西呢?原来它就是世界上最小的鸟——蜂鸟。 If you are traveling in the secluded mountainous forests of South America, you will see something like a meteor flying across the bushes. When you are looking for something, it disappears. Sometimes, you will see a strange “insect”, its body hanging in the air, making a “squeaking” sound, sucking nectar with a long mouth, when you want to look at it carefully, blink it It’s gone again. What exactly is this? Originally it was the world’s smallest bird, the hummingbird.
