Answer:
Foot-stirring is the most common. It involves moving one foot forward, and then wiggling it in a circular motion through aquatic plants and mud. Any fish that moves is quickly stabbed by the beak. Another variation is hover-stirring. For this, the egret hovers above the water, and again uses a foot to stir the water, catching any fish that move.
They have also been seen moving a foot slowly through the water above the mud, using the toes as a worm-like lure to attract fish.
Another foot strategy is "disturb-and-chase". The egret moves forward quickly, using its feet to scare fish, which it then chases. All in all, Snowy Egrets have been seen to use 34 different feeding behaviors, a truly amazing bird.
