Kill two birds with one stone.
一箭双雕;一举两得。
Fine feathers make fine birds.
人要衣装,马要鞍。
Birds in their little nests agree.
同巢之鸟心儿齐。
Birds of a feather flock together.
物以类聚,人以群分。
Each bird loves to hear himself sing.
鸟儿都爱听自己唱。(自我欣赏)
Its an ill bird that fouls own nest.
家丑不可外扬。
You cannot catch old birds with chaff.
(粗糠) 用粗糠捉不住老鸟。(有经验的人难骗。)
A bird in the hand is worth two in the bush.
双鸟在林不如一鸟在手。
A bird is known by its note, and a man by his talk.
听音识鸟,闻言识人。
