The tide is nearly low in the little tidal pond and the water depth is low enough for Great Egrets to wade across the middle.  Each step is slow and deliberate. The egret's long neck and head strain to the side for a better look or maybe to reduce the glare from the sun.  There is barely a ripple on the water to convey the presence of danger to its finny prey. Any little glint of scales or fins, or maybe the translucent body of a shrimp will be met with a lightning fast attack, and as often as not, a meal for the egret.  This is the way Great Egrets stalk their prey.
