This is a small squirrel feeder that can be mounted onto a wooden fence or wall. There is a small nail on the base on which you can place dried corn cobs. Squirrels (and birds too) will soon find this treat and you'll be running back to the pet store for more dried corn cobs before you know it. This item is made from cedar or pine and assembled with galvanized nails to withstand the elements. It can easily be taken down and moved to a new location.
