There are never enough holes and hideaways where wildlife can shelter - help them by making a nestbox.
House sparrows are a familiar sight in our gardens, but they're in trouble and struggling to cope in the modern world.
You can build a sparrow box whenever you like, but it's a job that can be done indoors on rainy days when there's not as much to do in the garden.
You should see the males proudly chirping from nearby, or even from the roof of the box. Don’t worry if sparrows don't move in right away – it may take a while for a family to start where you live. But you'll be ready when they do!
If you’re short on time or DIY skills you can buy a sparrow nestbox and put it up readymade. As an alternative activity, why not try decorating your box with paint? Painting your nest box is a really nice way personalising your box and making it your own!
Follow the instructions carefully and you could have a box that could be home to a brood of baby house sparrows. Exciting, eh?

Did you know That the record number of birds found in one box is 63 wrens! They are very small, but that's a lot of wrens.
What you will need
- A plank of FSC wood 15cm x 1.4m long x 1.5-1.8cm thick and not pressure treated
- Pencil and tape measure
- Strip of waterproof rubber
- Optional: a hole saw/cutter for making 3.2cm holes
- Camera or smart phone
- Water based paint
- Find the right bird-friendly spot for your box. Ideally, it will be under the eaves of your house or high on a wall, well away from curious cats or foxes! Make sure you get permission if you need it.
The box will need to be at least 3 metres (10 feet) from the ground, facing somewhere between north and east to avoid it getting too hot or wet. Avoid placing it in direct sunlight and don't put it over a doorway or well-used path.
- Make sure you have the right wood. The thickness is important to insulate the box from cold and heat and to stop the box warping. You can use exterior-quality plywood (for a light box) or, for something more sturdy, hardwoods (such as oak and beech) or soft wood (such as pine, but this will deteriorate more quickly). Buy timber approved by the Forest Stewardship Council – look for the FSC logo.
- Measure and cut your wood according to the diagram.
Note: the dimensions shown are for 15mm thick wood. If your wood is different to that, the dimensions of the Base should be 150mm by 150mm minus 2 x thickness of the wood, eg if the wood is 18mm thick, the base should be 150mm x 114mm.
If you don't have the hole saw/cutter for making the 3.2cm round hole, you can use a jigsaw (not the puzzle!) to cut a square or wedge-shaped hole at the top of the front, as in the diagram.
Remember: Adults should be in charge for all the steps involving sharp tools or nails!
- Nail all the pieces, except the roof, together. The sides, back and front 'wrap around' the base.
- Attach the roof. By using screws, you’ll be able to get into the box at a later stage to clean it out. Use a waterproof strip to make a hinge between the top edge of the roof and the backing board. Try a piece of bicycle tyre inner tube, damp-proof membrane or roofing felt.
- Decorate you box. Now it's the fun part that you can all get stuck into! You should have a nice complete bird box now, so it's time to get out the paints and give it a personal touch. Think about pattern and colour and create something really unique. Remember to use non-toxic water-based paints though! There's a handy guide to painting nestboxes here.
- Put your box up. Drill guide holes in the backing plate at the top and bottom of the box. Taking care, fix the box to a wall using a ladder, screws and Rawlplugs.
- What to look for. Sparrows will start house-hunting in spring. There is never a guarantee of them using your box, but if you're lucky you should see the males proudly chirping from nearby, or even from the roof of the box. Sparrows are sensitive to disturbance at the nest and protected by law. So watch and enjoy from a distance. You may be lucky to see them raising several broods in there in a season. Maybe you'll even catch some chicks fledging!
