a little birdie told me

The phrase "a little birdie told me" is an idiomatic expression used to convey the idea that the speaker obtained certain information from a confidential or anonymous source. It suggests that the speaker is aware of something that others may not know, often adding an element of intrigue or secrecy. The source of the information is humorously attributed to a small bird, metaphorically indicating that the information was obtained in a secretive or indirect manner.
