Parrot Tower Junior The perfect choice if our Premier Parrot Towers don't fit your space. Following its debut several years ago, the Parrot Tower Junior was an instant success. The Junior offers the same great features in a smaller size. Perch Diameter: Cockatiel size: approximately 1/2 inch. Our Java Perches have varying diameters for healthy feet. Includes: 10 perches for Amazons, 2 8-oz food bowls & holder, casters, 5 toy mounts (everything pictured except our birds and toys). Dimensions: 4' tall, and 25" x 19" Wide. Java Branches are naturally irregular and require a separate box for shipping.
