Die Antwort, ohne jetzt alles auf Deutsch zu schreiben. Kurz gesagt "Wölfe agieren so per Natur! und wenn es noch Zeit gibt, gehen sie wieder dort und essen, was sie bis jetzt nicht getan haben! Originally dubbed “surplus killing” (Kruuk 1972), this phenomenon has also been called “excessive killing” (Carbyn 1983). A fine distinction between the terms has been proposed (Miller et al. 1985), but it is arguable whether this distinction has any relevance. In both cases, wolves kill more than they can immediately consume. However, if sufficient time passes without scavengers finishing off the carcasses, wolves do return and feed on what researchers originally regarded as surplus or excessive (Mech et al. 1998, 2001). Banfield (1954, 49) perceived this behavior more than a half-century ago when he wrote that “what may appear to be excessive killing by wolves seldom goes unutilized in the long run.” The fact is that wolves are programmed to kill and eat whenever they can because generally it requires considerable time, energy, and risk most of the time to do so.
