Comprehensive resource for understanding and mastering English idioms
The idiom "birds of a feather flock together" means that people who have similar interests, personalities, or qualities tend to spend time with each other. It suggests that birds of the same species are attracted to one another and prefer to travel together in large groups. This idiom is often used to describe how people who share common characteristics tend to form social groups and interact with one another more frequently than those who do not.
The idiom "birds of a feather flock together" has been used since at least the 17th century. The earliest known usage can be traced back to John Dryden's poem "Annus Mirabilis," published in 1684, which includes the line "Like parrots, which are of one kind, / Fluttering and squawking, if you touch them." This suggests that birds of a feather flock together because they are attracted to each other. Over time, the idiom has evolved to refer specifically to people who share common interests or qualities. It is now commonly used in contemporary language to describe how people tend to form social groups based on shared characteristics. The idiom may have regional variations depending on the culture and language spoken in different parts of the world. For example, in Spanish, a similar expression is "De pájaro feo," which means "of a different kind of bird."
