ANIMAL SAFETY: The transparent plastic front window offers the squirrels a clear view of where they can find their food. The opening has a safety gap to prevent injury to the squirrel if the lid closes while it is eating. FEED 'EM: Recommended food includes nuts, hazelnuts, sunflower seeds, peanuts, and raisins (food is not included in the delivery). Keep squirrel feeders well stocked at all times to prevent squirrels from straying from their feeders. PROTECTION FROM RAIN: The metal roof is made of iron to protect the feeding station from rain, so less moisture enters the wood. EASY TO MOUNT: Hang the wooden feeder on a tree in an area that is quiet and accessible to squirrels. Enjoy watching squirrels grabbing and eating their food from afar!. NUT HOUSE: With the Navaris Squirrel Feeder, you can offer squirrels a safe environment to eat nuts in the backyard, garden or forest throughout the year. Squirrel feeders give them a source of food apart from your bird feeders.
