It is really entertaining to have a squirrel feeder outside the window. Squirrels are clever little acrobats. It won't be long before they figure out how to get the food by sitting on the platform and pushing the roof up with their heads.
The squirrel feeder comes with a mounting plate for installation on a wall, tree or post.
Feel free to fill the feeder with hazelnuts and peanuts, but bird seed mixes can also be used. However, be careful with wheat, corn and Brazil nuts, as they are not good for squirrels.
