Animal migration event?

I've noticed that when this event pops it often proceeds to then pop several (2-3) more times in a row in the same city which seems a little excessive. When it happens it only seems to happen at the beginning of the game in the capitol city.

That is what "random" is all about. It happens fewer times than it did.
