Loplop, or more formally, Loplop, Father Superior of the Birds, is the name of a birdlike character that was an alter ego of the Dada-Surrealist artist Max Ernst. Ernst had an ongoing fascination with birds, which often appear in his work. Loplop functioned as a familiar animal. William Rubin wrote of Ernst "Among his more successful works of the thirties are a series begun in 1930 around the theme of his alter ego, Loplop, Superior of the Birds." and the drawing and collage Loplop Presents (1932) was used as the frontispiece of Patrick Waldberg's book Surrealism. followed by a number of works into the mid 1930s, forming an informal series of collages, paintings, and mixed media works.
