Included in the Garden Gadgets at Gizoo, I think this useful bird feeder works great in balconies as well. Actually, I’m planning to get one in the near future and attach it on my bedroom’s window and, why not, on the balcony as well. The Window Bird Feeder can help many birds survive during winter and would also make your garden look more alive during summer.
Designed like a bird house, the Window Bird Feeder has transparent walls, access from three sides, and holds both water and seeds. It’s easy to set, clean and fill. Find it at Gizoo at £9.95.
