What was the motive of the goose in that video? Did it think the man stored all the food on top of his head?

I'm seriously pretty sure the goose was trying to mate with him... Notice he isn't trying to bite or hit him with his wings, but attempting to grab him on the back of his head. Males do that to the females to hold on while gettin' it on.
We raised chickens, okay. That's why I know. I'm not into bird porn, I promise.
