Herbivore Showdown

On Friday afternoon, I got a glimpse of a 'showdown' between representatives of the two great endothermic terrestrial animal lineages... put in normal person terms, a woodchuck got into a standoff with a family of geese:

This showdown was preceded by a tiff between two woodchucks, with one chasing the other right past the geese until the pursuer set off the parenting instinct of the adults. Confronted by two hissing theropod dinosaurs, the large rodent decided to beat a hasty retreat.

I had the advantage of being on a raised porch above this particular fray. I doubt that the woodchuck would have approached the vicinity if I had been at eye level.
