In two holes made on top in the package, the cord is threaded and tied. The length of the cord is selected independently, looking at the location of the feeder itself. If this bird «restaurant» is located against the wall, then the entrance to the feeder should be cut on one side. But if the feeder is planned to be hung on a branch, here it is better to cut out the entrance to it on both sides. This simple solution will serve as the convenience of birds. In all cases, the hole is made about five to ten cm.- Paying attention to the volume of the bottle. A similar method can be designed by a feeder using a plastic bottle.
