Why Do Birds Sing? is the fifth studio album by Violent Femmes, released on April 30, 1991. It was the band's last album with original drummer Victor DeLorenzo, who left two years later to devote his time to acting, and was produced by Michael Beinhorn, best-known then for his work with the Red Hot Chili Peppers on Mother's Milk and The Uplift Mofo Party Plan.

The album featured the single "American Music," which rose to number 2 on Billboard's Modern Rock chart during the week of May 18, 1991, and became a staple of the band's live shows.
