IT CAN take up to 140 years for a nestbox to form in a eucalyptus tree.

This book is hoping to help that process along.

The Nestbox Book, by The Gould Group. Wilkinson Publishing, rrp $11.99

Nestboxes are the natural tree hollows that form as trees age and drop their branches.

The dead branches become infested with fungi and insects, which eat out the dead wood, leaving long, thick-walled hollows.

But in today's world, urbanisation and forest harvesting have increased the value of man-made nestboxes.

Attracting native parrots, kookaburras, owls, possums and other little creatures, the nestbox not only provides shelter for our fury and feathered friends but allows us to enjoy the wonders of nature.

The nestbox book explains how to properly construct and install a nestbox, with detailed diagrams and instructions.

It is easy to read and contains an array of cute pictures of Australian native animals as they take refuge in these self-made and well-camouflaged homes.

For years, The Gould Group has been dedicated to teaching innovative and environmentally friendly practices.

The most common nestbox lovers are listed, with facts about each animal and habitat maps.

This is a must for bird and nature enthusiasts.
