Once, three Crows and two Sparrows lived in a forest. They all were good friends. They would meet every day and fly around together from one place to another. The Crows would repeatedly look for food and the Sparrows for a place to make their nests.
One day, the Crows said, “Let’s explore this part of the forest. Someone told us there is lots of food here.”
The new part of the forest was beautiful and there was, indeed, plenty of food. However, there was only one large tree. The Sparrows and the Crows all wanted to live there.
The Sparrows told their aunts, uncles, cousins, grandparents and friends about the new place. Everyone wanted to live there. The Crows also did the same.
Soon, a big fight broke out among the birds. The Crows said, “We found the place first, so we will live on the tree.”
The Sparrows said, “So what? We will live there. We found the tree first.”
After this, the two Sparrows and three Crows could not be friends anymore.
They constantly fought with each, “You Crows are bad.”
“You Sparrows are fools!”
Thus, they went back to their own kind.
Birds of a feather flock together. Birds of the same kind are often seen to flock and fly together. A swallow would not be seen to join a goose and vice versa. Some special kinds of birds which cross the seas in search of warm regions go in flocks.
This is because a bird can be comfortable only in a flock of its kind. This is the case in human beings also. Those with similar tastes and interests almost always form groups and associate with one another.

Birds of a feather flock together
「Birds of a feather flock together」是擁有同樣羽毛的鳥會聚在一起，也就是「物以類聚」；或是負面涵意的「一丘之貉」，例如：
They’re birds of a feather, they both like football, snooker and drinking cola.（他們都喜歡足球、撞球還有喝可樂。）
Don’t be friends with bad boys. People think that birds of a feather flock together.（不要和壞孩子成為朋友，別人會認為你們是一丘之貉。）
I’m not surprised these two are such friends ; they are birds of a feather flock together（這兩個人交上朋友我毫不奇怪，他們氣味相投。）
You know me better than others, vice versa.（你比所有人更為了解我，我也比所有人更為了解你）。
Balance indicates existence, and vice versa.（平衡即是存在，反之亦然。）
She has a good impression of me and vice versa.（我和她彼此都有好感。）
Like Water Off A Duck’s Back
Tom’s uncle: How’s Tom getting on at school?
Tom’s mom: Well, his last report wasn’t very good actually.
Tom’s uncle: Oh dear. Why not?
Tom’s mom: Because he just won’t work. He’s only interested in sport, and he just won’t put any effort into anything else at all. We’ve tried everything. we’ve stopped his pocket money – we don’t let him go out in the evenings. In fact, last week we even went to see his headmaster. But he just doesn’t take any notice of anybody.
Tom’s uncle: But surely he can’t enjoy all that? I mean, it’s not very pleasant to be criticised all the time, is it?
Tom’s mom: It doesn’t bother Tom. It’s like water off a duck’s back. He’s got a thick skin. It doesn’t matter what you say, it won’t upset him.He’s got a skin as thick as a rhinoceros.
湯姆的媽媽：因為他不作功課。他只對運動感興趣，他根本不肯為其他學科付出任何努力。我們什麼都試過了，我們不再給他零用錢 ，不讓他在晚上出去。 事實上，上周我們還去拜訪他的校長，但任何人的警告都吸引不了他的注意力。
