How to make a birdhouse
Building a birdhouse or nesting box is quite simple. And it’s a fun job to do together with the (grand-)children.
Make sure you use weather-resistant wood like oak or beech, or otherwise you can use water‑resistant plywood. Place the birdhouse at least 1.5 meters above the ground to protect the birds from predators like cats. It’s best to place the birdhouse on the north side of the tree, for better shelter from rain.
As an example, we’ll take a suitable size for small birds like finches and great tits. You can make all the walls from a single plank of 15 cm wide. The best thickness is around 20 mm. Make the roof at an angle so rain can easily run off.
- 1 rear wall 38 cm long
- 2 side walls of 22x26 cm long
- 1 roof of 18 cm long, or slightly longer to allow water to run off
- 1 front of 23 cm long with an entry hole of ø32 mm
- 1 base of 12 cm long
- 1 mounting post, if possible placed in the life of flight of the birds (with a pre-drilled hole)
- wood glue
