Résumé :	The variation of the "clattering" was studied in groups of 9 female and 9 male individually marked White Storks in the southern part of Rhineland-Palatinate. We gathered and compared data to find a gender-based characterization in this instrumental noise. A separation of genders was possible by a simple 2-d matrix of the parameters F2M [Hz] and DIK [ms], based on mean of each individual. We assume that the discovered differences depend on the anatomic dimorphism of the beak and of the anatomy of the head.
