"Birds of a Feather" is a song by Lana Del Rey written and recorded as May Jailer. It is the fifteenth and final track on the album Sirens. It differs from the other tracks on the album as it heavily features auto-tune.
While not directly referring to the song, Del Rey first used the song title to describe the story of her and a lover depicted in "Off to the Races" during a 2012 interview with TV Italiana. Del Rey later referenced the title again to describe her friendship with James Franco during the Beats 1 interview with Zane Lowe on August 10, 2015, while promoting Honeymoon.
