The relation between Marabou Storks and Vultures, Serengeti

This photo shows the relationship between Marabou Storks and vultures. At a first glance, judged by size and strength, these Marabou Storks could easily chase away or kill the vultures. The only reason why they won't is that vultures have the tools to cut prey into small pieces, whereas the bill of the Marabou Stork is useless for cutting. Thus, as you can see, the storks are patiently waiting for the vultures to produce snack-size bites. Only then will they strike.
