When the doors are closed the rubber flashing on top of the feeder prevents rain from entering the feeder. When feeder doors are open The Gull Wing Door design minimizes rain from entering the feeding area when the doors are open. In an event that you experience a sideways rain storm our feeder is designed to allow any water that may enter through the side of the product to escape through the bottom of the feeder. We are also developing a rain sensor that will be offered as an accessory at a later date.
