Know thy enemy.

The American Widgeon is often found feeding with diving ducks such as the Redhead, Scaup, and Canvasback, who are adept at rooting up vegetation from deep in the water. The American Widgeon often feeds by snatching these underwater greens away from the diving ducks as they surface. The American Widgeon is more restless than most ducks, and is quick to sense trouble and will launch itself into the air with a flurry of alarm calls and beating wings, thus alerting the less suspicious diving ducks around it of the existing danger.
