To make a bird feeder, we need a plastic bottle with a volume of one to two liters (the best is square), a piece of wood, and a piece of nylon thread about three millimeters thick. Of the tools you need a sharp clerical or simple kitchen knife:
All operations for making a bird feeder are best done on a stable table with a flat surface. With a knife, carefully and without undue effort, at a height of ten centimeters from the bottom, cut a square hole seven by ten centimeters in the side wall of the bottle. In order not to cut yourself while making a cut, it is best to firmly press the bottle to the table. The next step is to make a hearth by which the birds will go into the feeder.
To do this, take a piece of wood prepared in advance and cut from it the required pole twelve centimeters long and five millimeters in diameter. With the same knife, cut a hole a centimeter below the entrance to the feeder and insert a six into it. The feeder is almost ready, it remains to hang it for something on a tree, for this we attach a nylon thread to the neck and tighten it with a cork. Now we are ready to welcome the birds.
