Correction alert: Birds of a feather flock together

The correct saying is not ‘birds of the same feather flock together’ but ‘Birds of a feather flock together’.

This expression means that people who have things in common are usually seen together. It is often used when you think such an association will bring no good.

Examples:

1. We didn’t know he was a fraudster until we met his friends. Indeed, birds of a feather flock together.
2. You’d know birds of a feather flock together when you see the duo.
