Background and release
Billie Eilish first previewed "Birds of a Feather" on May 13, 2024, through a teaser trailer for the third season of the Netflix series Heartstopper.

Composition
A pop, baroque pop, indie pop, new wave, and synth-pop song, "Birds of a Feather" borrows its title from the English idiom "birds of a feather flock together". In an "emotionally vulnerable" tone, Eilish sings about falling in love with a person that she wants to "stick together" with. The love for her significant other brings her to tears, and she begs her lover to stay and never end their relationship.
The song is composed in the key of D major in a common time and features a tempo of 105 beats per minute.
Critical reception
Mikael Wood of the Los Angeles Times described "Birds of a Feather" as a "breezy neo-new-wave jam", Alisa Ali of NPR wrote of the song that "poignant lyricism hides amid the dark humor and [Eilish's] clever cadence makes for one of the singer's most memorable vocal performances". Tom Taylor of Far Out classifies it as "a classic pop chorus with Eilish burst out in a blushing '80s pop vocal", adding that it "has a sort of hook that would have old-fashioned music bigwigs screaming, 'It's a hit', but cleverly, the song doesn't give itself up to that and heads back to nuanced verses, layering in a touch more sincerity to undercut the bubblegum synth whistle". In 2026, writers for Time Out named "Birds of a Feather" the best love song of all-time.
