House A Bird – Hanging A Nesting Box #HowTo

Nesting BoxFall is the best time to start putting up nesting boxes. Birds can take a long time to decide where to nest in the spring and they often ‘try out’ a box over the winter before they decide whether they want to nest there or not. So for your best chance of housing an avian family in spring, give them plenty of options now.

You will need:

  • A wooden nesting box
  • A Ladder
  • Galvanised screws
  • A screwdriver
  • Wire or twine
  • Garden Hose

How to do it:

  1. First of all, take a walk around your home & garden to find the best possible place for your bird box. The best spot is a cool place facing north east and between 2 m & 4 m off of the ground.
  2. Now it’s time to choose your nesting box. Some things are important – Do not buy a box you cannot open to clean. If you do, after the first bird has nested there it will not get used again. Don’t buy a box with a perch below the hole. Larger birds will use it to perch on while the reach into the box. See the table below for details of the preferred dimensions & other specs for specific breeds.
  3. If you are affixing the box to a tree, thread enough twine to reach all the way around the tree + 10 inches, through some garden hose. Tie the hose around the tree at the height you want your nesting box. The tube will protect the tree from damage. Fix the nesting box to the hose.
  4. Birds prefer to line the boxes themselves, but you can help by loosely tying small bundles of twine, wool, pet hair or similar for them to use.

You can mount your box in any number of sites – different species like different types of location. These pictures will give you an idea of the kind of spots that work. Good luck & remember to keep a notebook & pen near the window to record your new guests.
