Introduction: Simple Bird Nesting Box

Make a home for our feathered friends to raise their young.

This is a simple open fronted bird nesting box for small to medium sized birds such as song thrushes, (European) robins, wrens and flycatchers. I was going to publish an Instructable to make a box for hole-nesting birds, but Cheapchuck has done such a good job HERE, I'm going to make a few of his.

Some birds which were once common are declining with the loss of habitat and changes in climate, and gardens are a valuable refuge. Wild birds are very entertaining to watch and any effort to attract them to the garden and help them to breed is well worthwhile.

You also have the added benefits of free pest control. Birds, especially during the breeding season, will hunt down and eat many garden pests. It has to be better to encourage a natural balance of wildlife in your garden than to upset the eco-system by spraying with pesticides.

Step 1: Tools and Materials

You will need a saw, a hammer, some 30mm panel pins, wood glue, a measure, a marker and a piece of wood around 3 foot (1 metre) long, 6" (150mm) wide and 1/2" (12mm) thick. A drill would be useful for drilling mounting holes, but not vital.

I used a piece of rough pressure treated timber which had been at the back of my shed for many years. If you are buying new, use plain timber. It won't last as long as treated timber, but recently treated wood can harm the birds you're trying to help. Building the box took me a bit over an hour and that included designing it, so with a bit of effort, you could make a few in an afternoon.

Step 2: Measuring and Cutting

Mark out the wood and saw into the required parts. Note the one sloping cut, which is going to give a slight angle so rain runs off the roof.

If you're using different width or thickness timber you will need to adjust the measurements. If you cut the side pieces first it's pretty easy to work out what you need to change by holding the sides against the back-piece and measuring the required lid-width and length. The lid length will be the width plus twice the thickness. The length of the base will be the width minus twice the thickness.

I've given measurements in Imperial and metric units, although nothing needs to be exact as anything you make is going to give the bird a palatial home much more secure than some of the places you find them nesting.

Step 3: Putting It Together

Hammer the panel pins into the sides so they just come through the other side. This makes things a lot easier when you put the box together. Use a PVA based wood glue to give extra strength. Put a thin bead of glue along the edge just before you hammer the nails home.

First, attach one of the sides to the back-piece, and then fit the base. Turn the box over as you're doing this, so you're always hammering into the piece against the workbench. Then put on the front of the box, not forgetting the bead of glue on the edges.
Now more glue, and carefully line up the other side and press down. The protruding nails will keep it aligned. Hammer the pins home. You'll need to put a few more panel pins through the front and back-piece into the base.

Step 4: Finishing

Finally, steady the box on the bench, add glue and pin down the lid.
Work a bead of glue into the crack where the lid meets the back-plate to keep rain out. Also rub some glue into the end-grain at the top, sides and bottom with your finger to stop water being absorbed so easily.

Drill a couple of holes, top and bottom of the back-plate so you can attach the box to a tree branch. If you don't have a drill, cut two pairs of notches at the sides level with where the holes would be

There are wildlife-safe wood preservatives available and you can treat the outside with one of these if you wish, but never use normal preservatives such as creosote. Never treat the inside.

It would be safe to paint the outside, but I much prefer the natural look and even new wood will quickly weather,


Step 5: Location, Location, Location.

Use thick wire to tie the box top and bottom to a sturdy vertical branch or trunk of a tree. Either wire through the holes, or use the notches to make it secure. If the tree is still young the wire will dig in as the branch thickens, so it should be re-tied every year. The box should also be cleared out each autumn (fall) to prepare it for the next spring.

Where you put the box will determine how successful it is.
Different birds have different preferences, but in general it should be :-
At least 8 foot off the ground to keep safe from predators.
Not too near a food source, or other place where birds gather.
Semi-shaded, and definitely not in full sunlight.
Partially hidden by foliage, but with a clear flight-path to it.

If you live in town and don't have a suitable tree, put a box under the overhang of the house. Town birds need even more help as they have a very limited natural habitat.

*** UPDATE ***
We've now got a family of wrens living in the box, which makes it all worthwhile.

I think quail nest on the ground. Easy enough to modify the box to suit, though.

Excellent. Thank you very much for your response. I don't have too much truble with crows here, however the squirrels are an absolute nuisance. I do have a section of my backyard fence that has more ivy than other parts that would allow for too much sun. I think I'll give that a go. Great bird box, love the simplicity of it!
thanks very much again

Hi
I live in NYC and the city is loaded with Robins with red bellies. Love your simple box! Just one question: have you had any trouble with predators with box that is right up against the tree? Or is the box small enough that none have given it a go?
Again, great bird box!

I've only been to NYC once - Incredible place, but I wouldn't want to live there as I'm a country boy at heart. For a densely packed city it's amazing how many green areas there are.

As I've said in a comment above, in the UK our main predators are the crow family and squirrels but the box is now so well hidden in the ivy that you can hardly see it.
Spring hasn't arrived here yet this year but we're hoping for another boxful of birds.
I've also made a few based on CheapChuck's design linked above which have had blue-tits in them in previous years.

Looks great...hope ya do not have a lot of raccoons around...they LOVE to raid the eggs out of the nest.

You know, I've NEVER seen a raccoon around - Here in England our main predators are foxes, rats, grey squirrels, magpies and jackdaws. (We need to go to the zoo to see raccoons :-)

god i love foxes... i might go see if i can track some down. any suggestions?

Yay im in england !!

I saw 2 racoons up a tree a few blocks away from where I live about a week ago...
our main predators are grey squirrels, red squirrles, Jays, Magpies and Survivor man

wow. over where i live (california, usa) we have raccoons, crows, and MAYBE foxes. I might go see if i could find a couple of foxes.
