Twittering Machine (Die Zwitscher-Maschine) is a 1922 watercolor and pen and ink oil transfer on paper by Swiss-German painter Paul Klee. Like other artworks by Klee, it blends biology and machinery, depicting a loosely sketched group of birds on a wire or branch connected to a hand-crank. Interpretations of the work vary widely: it has been perceived as a nightmarish lure for the viewer or a depiction of the helplessness of the artist, but also as a triumph of nature over mechanical pursuits. It has been seen as a visual representation of the mechanics of sound.
