Great Egret, Red Horse signs, vintage poster on wood, measures 15 by 26 inches. Artist Anthony Morrow. A tall, stately white wader of quiet lakes, rivers and marshes. Common in the south, it may wander far to the north and even into Canada in summer. A frequent visitor to Robyn's Lake House, the Great Egret may stand over 3 feet tall and possess a wingspan of 6 feet. When it takes flight, one hears the familiar, swoop, swoop, swoop of its wings. It is a wonder how such a large bird can take flight.
