Bird House Design
How elaborate you make your bird house depends
on your own tastes. In addition to where you place the box, the most
important considerations are: box height, depth, floor dimensions,
diameter of entrance hole and height of the hole above the box floor.
Refer to the following chart before building
your nest box, keeping in mind that birds make their own choices,
without regard for charts. So don't be surprised if you find tenants
you never expected in a house you intended for someone else.
