2-in-1 Bird nesting box and Squirrel feeder For squirrels open the large hatch and close the rear round opening. This wooden feeder will help attract squirrels to your garden. It holds around 750g of peanuts, but you can fill it with other foods they like such as grapes, corn, squash, zucchini, pumpkin, strawberries, carrots, apples or seeds. For use as a Bird box close the hatch door and open round opening. The 25mm hole and the size of the box is suitable for a variety of small birds to nest inside roost in the winter. In rural areas, there is a huge shortage of safe natural nesting places for birds. We can all help with this by putting up nesting boxes and encourage them to breed near your home.
