The early bird catches the worm.
早起的鸟儿有虫吃。捷足先登
A bird is known by its voice, and a man by his words.
闻声知鸟，闻言知人。
Every bird likes its own nest best.
鸟均爱其巢，人皆爱其家。
There are no birds of this year in last year's nest.
时过境迁。
If you sell the cow,you sell the milk too.
事难两全。
No bees,no honey.
不劳无获。不劳动，不得食。
One swallow does not make a summer.
独木不成林。一花独放不是春。一燕不成夏。
A bird in the hand is worth two in the brush.
一鸟在手胜过双鸟在林。
Every dog is lion at home.
狗是百步王，只在门前狠。耗子扛枪窝里横。
The scalded dog fears cold water.
一朝被蛇咬，十年怕井绳。
