The Bird Feeder is made from recycled materials is fun for all, including the birds! A clear Polycarbonate window makes it easy for viewing birdseed, so you know when to add more. We’ve designed this Bird Feeder with a hinged lid for refilling without making a mess. Birds love the little perch with access to the seed and kids love seeing the variety of birds. The sturdy construction and recycled RSP materials ensure this bird feeder will last for years to come.
