Birds of a feather flock together
Possible interpretation: "Birds of a feather" means "birds of the same type". The whole proverb means that people of the same type or sort stay together. They don't mix with people of another type.Note: feather (noun) = part of the soft, light covering of a bird's body | flock (verb) = gather in a crowd | This proverb reminds us of the proverb "Tell me who you go with and I'll tell you who you are."
