When they first arrived at the water hole, the female went in the water and drank. Then a bull arrived and cow moose amicably shared the water hole with him.
He arrived like a mack truck, barreling into the pair of moose and making them move out of the water.
The male in the pair who was just bullied out of the water looked hard at the moose who had thrown him out but no fight broke out. The moose who had successfully claimed the water was definitely the biggest of the three.
Then, the biggest moose monopolized the water for the rest of their time at the water hole. He lay down in the water and did not budge even when the others paced past him. Finally, when he saw the other two leaving, he abandoned the water to follow them. I hope that they forgave him.
Here's a video of the trio at the water hole. You can watch at YouTube:
