Recently, Abraham and Delmas constructed the distributions of super-critical Levy trees truncated at a fixed height by connecting super-critical Levy trees to (sub) critical Levy trees via a martingale transformation. A similar relationship also holds for discrete Galton-Watson trees. In this work, using the existing works on the convergence of contour functions of (sub) critical trees, we prove that the contour functions of truncated super-critical Galton-Watson trees converge weakly to the distributions constructed by Abraham and Delmas.
