Question: Which North American heron is most inclined to forage using foot-raking or foot-stirring?
Answer: The Snowy Egret is the most frequent user of the technique.
It starts from a low perch and flies over the water's surface, dragging its feet on the water's surface. When the fish scatter because of the shadow and the motion in the water, the egret stabs down while flying to catch the fish, and then it returns to its perch to eat.
