Take a yogurt container and nail the lid onto a vertical board or fence.

Carefully make a 4 centimetre (1.5 inch) hole in the bottom of the yogurt container.

Carefully make 3 nail holes on the side of the yogurt container that will be on the bottom. They are used to drain water if the rain gets in.

Securely fasten (glue/tape) the container to the lid.

Watch and see if any birds use your home made nest.

If they do, take a picture, send it in (as a jpeg or mail it as a print), and Global Forest will post it in the GF-Gallery along with your name and we will mail you a GF series sticker for your GF collection.
