Wildlife Sciences introduces two new Fly-through Suet Feeders. With the popularity of fly-through bird seed feeders, Wildlife Sciences decided to design our own Fly-Through Suet Feeders. The feeders are attractive and durable with powder coated metal components and antiqued copper roofs. Our Fly-Through Suet Cake Feeder holds four standard suet cakes and the Fly-Though Suet Ball Feeder is designed for our unique suet balls.
