[EBB Sightings] American Crow Leapfrogging Canada Goose

Yesterday I witnessed what seemed like some very bizarre behavior by an American Crow. Two Canada Geese were grazing at the north end of the Springtown Golf Course, in short mowed grass far from any trees or shrubs.  An American Crow was repeatedly jumping over one of the geese, hitting the goose on the back with its feet on the way.  This happened about 25 times in about five minutes, all silently. The goose seemed oblivious to all this, only lowering its bill and advancing toward the crow once.  A couple of times the crow seemed to stumble upon landing, pitching forward wih its open bill in the grass, but immediatly recovered, turned, took a couple of steps, and jumped over the goose again.  The two geese continued to graze, while walking slowly. In the meantime, I was moving closer for a better look, and finally, the geese walked away from me, and the crow pecked at the ground a few times, then flew.  I looked closely at the spot where the crow had pecked, but could find nothing, just short grass with some clover mixed in, and a few dried-up whitish clover flowers.  Not even any goose droppings.

Has anyone ever seen this kind of behavior before?  Can anyone explain its purpose or significance?  Any thoughts?

I suppose one possibility is that the crow had been attacked in a similar manner by a blackbird, which I have seen frequently, and decided to copy that behavior.
