We call this bird feeder "The Essential" because it mimics a natural feeding position for birds. The paddle simulates a tree trunk and allows birds to prop their tail while they feed on the Suet Cake inside the cage. Birdwatchers and nature lovers will enjoy watching the birds feed on this tail prop suet feeder because you will have a clear view of the birds with no visual obstructions. These feeders are very popular among woodpeckers, nuthatches, bluebirds, cardinals, chickadees, and wrens. These unique, handmade bird feeders have been designed and created with highly reputable Amish craftsmanship right here in the USA. Every detail of these pieces have been thoughtfully planned out so that you get the best of the best. Each bird feeder is made with Poly Lumber and 100% post-consumer recycled plastic; a wonderful way to take care of the Earth while simultaneously enjoying the Earth's beauty. To ensure no maintenance is needed on these feeders, our builder uses stainless steel screws and cables, aluminum screens, and UV protection.
