Although nestboxes cannot replace the millions of tree hollows that have been lost, they can be of great benefit to wildlife in areas of human habitation, where hollows are extremely rare. Nestboxes can be placed so that you can watch birds and mammals breed and go about their daily business. Nestboxes can allow you to see animals in your area that are normally so small or secretive that you won't see them. Beautiful little feathertailed and sugar gliders, for example can be seen leaving nesting boxes for each evening in some areas. Nestboxes are great fun, and we hope that you will learn much from them about your local Australian wildlife.
