Features 1. Detail design: The four feeding ports are designed for birds to peck at seeds, and squirrels find it difficult or can only obtain very few seeds. The top cover of our bird feeder is made of metal, and there is a metal clip that holds the cover in place, making it difficult for squirrels to open or bite the cover. The seed tube inside is wrapped in an iron spring, making it difficult for squirrels to bite into the food tube to obtain the seeds. All details are designed for better bird feeding and have design patents. 2. Internal food tube design and weather resistance: The internal food storage tube is made of thick transparent plastic material, which can easily observe the condition of bird seeds. It is suitable for most bird seeds, such as millet, black oil, and striped sunflowers, saffron, peanuts, etc. The metal surface is coated to prevent rust, and the roof can protect seeds from rain and snow. For the convenience of birds, the habitat of the feeding port has also been expanded. 3. Anti squirrel bird feeder: A metal spring is designed around the seed tube. When the squirrel climbs onto the bird feeder, the spring will stretch and the feeding port will be blocked by the spring, making it difficult for the squirrel to obtain the seeds. 4. Attracting Wild Birds: Our wild bird feeder adopts a green and unique design, which will better attract birds and is also a cute backyard decoration. You can enjoy your favorite birds up close, such as Cardinals, Sparrows, Sparrows, and Bluebirds. For those who love birds, this is a great gift.
