I spotted these Canada Geese resting on a river bank in a Wyoming wilderness meadow. As I approached them I had to stop many times for them to get used to my being there. When they would lay back down, I would creep a bit closer. Finally as the one on the right sounded a warning, signaling a severe encroachment, I snapped the shot before I lost it. Sure enough after a few seconds they all took off and hydroplaned to a stop on the river a few hundred feet down stream.
