        The new flying cage for aquatic birds in the ravine near the Connecticut avenue entrance will prove one of the most interesting features of the Zoo. It is fifty feet in length, of corresponding height, and has a miniature lake its entire length. It contains fifty-five fine specimens of aquatic birds, from the big marabou heron, four feet in height, to the little heron of twelve inches. Cormorants, snake-darters, pelicans, great blue herons, European storks, and other water birds make a lively scene.
