Neveu studied leaf-length erasure of Galton-Watson trees, Geiger and Kauffmann the subtree spanned by vertices picked uniformly at random and Duquesne and Winkel the subtree spanned by leaves picked uniformly at random, each finding that the reduced tree is also a Galton-Watson tree. We observe that the offspring distributions that occur in the three examples are the same, and we introduce the...
