Hmm .. I always see the major reaction to a threat from herd animals is to 'leg it', not hang around to warn the herd & see if everyone is OK.
the point was that they do it as a group, it is the 'safety in numbers' approach, I meant. Often, even when 'legging it', the younger/weaker members of the herd are in the middle of the group & less likely to be 'picked off'.

- it is quite amazing how close a herd of, say, Zebra, will allow a predator to come, provided they can see it - but it is usually the strong, fit ones that do the 'facing', and once they decide to run, the rest of the herd have a head start.
