As Chris says, Cattle Egret. Short and stumpy look and the cinnamon-buff patches on back and crown are good Cattle Egret characters (latter a breeding-plumage one, so disappears in non-br.). Yellow bill rules out Little Egret, as do the pale legs. The stocky look, shortness of bill, short neck and legs all rule out Great Egret.
