The birds can enter the bird feeder from both sides or from the front to get food, and the practical design provides the birds with comfort. 2. Sturdy and durable: The transparent acrylic window bird feeder is made of highquality acrylic material, which maintains transparency and prevents yellowing over time. The weatherproof design is suitable for all weather conditions. 3. Drain hole design: You can put seeds, sebum, fruits and other foods into the feeding area. After rainy and snowy days, this bird feeder can effectively drain the water in the tray, which keeps the bowl dry and prevents mould.
