when I was a kid we used to play 'king on the hill' (sort of a human instinct game of who is boss) where on some small mound of earth or boxes or what ever everyone would try to become the only one standing upright on that mound after furious minutes of flailing, throwing, tripping and what ever method not involving actual fisticuffs although many a nose was bloodied in the process depending on where we played
but here on this log the Mallards seem to be king(s) simply by being first while the geese are waiting patiently for their turn [just dumb beasts, eh?]
