★ This perch is 10mm thick. Suitable for Bengalese finches and Java sparrows. Perfect for baby birds! Made from Aomori Hiba and American Hiba. I made this on a whim. It can be used by young birds to old birds. I've created a perch that can be used for rehabilitation, muscle training, and singing and playing. The height is about 3cm, so even if they fall, they'll be fine! (*•ω•)b Up to 3 birds can perch together, so you can give them treats? You can also take photos of them being friendly! Size: Stable, 3cm thick, 4cm square. This perch is 10mm thick. Suitable for Bengalese finches and Java sparrows. Perfect for baby birds!
