Things You'll Need
Instructions
Build a rectangular box that is 23-by-32-by-20 inches. The box should be shallow. Falcons won't nest in anything that resembles a cave.
Position the falcon nest box on its side. Use scraps of wood to create a ledge 3 to 4 inches from the edge of the box.
Drill holes in the bottom for drainage purposes. Use a drill with a paddle bit attachment. The holes should be small to prevent harm to the falcon.
Utilize small, smooth gravel for a nest substrate and make it 3 to 4 inches deep. If the gravel is rough the eggs will crack.
Observe the falcon in your area to determine where you should place the falcon nest box. It should be placed in a high location near water.
