蜂鸟是世界上最小的鸟类,有的只有黄蜂那么大,从头到尾还不到2厘米,最大的也不过4.5厘米。更有意思的是,它们飞起来像蜜蜂一样,会发出嗡嗡的响声,也喜欢吸食花蜜,所以给它起“蜂鸟”的名字是再合适不过了。 Hummingbirds are the smallest birds in the world. Some are just as big as the wasps. They are less than 2 centimeters from the beginning to the end and the largest is only 4.5 centimeters. What’s even more interesting is that they fly like bees and they make a buzzing noise. They also like to suck nectar, so it’s more appropriate to give it a name called Hummingbird.
