Wooden, square bird perch, attachable with screws. - Material: Wood - Shape: Square - Attachment: Screw-on - Use: Bird perch Thank you for looking. I purchased this with natural wood imperfections from the start. Suitable for Java sparrows and Pacific parrotlets, I believe. My bird doesn't like the color of this wood and gets upset when it's attached, so I'm giving it away. I only attached it to the cage for a few days, and as far as I can see, my bird didn't use it.
