Materials You Will Need

Untreated softwood at least 15mm thick, galvanized screws and a drill with a 25mm hole saw for a blue tit entrance.

Entrance Hole Sizes

25mm suits blue tits and coal tits; 28mm admits great tits. Skip the perch — birds don't need it and it helps predators.

Where to Mount Your Nest Box

Fix the birdhouse 2–4 meters high, facing between north and east, away from direct sun and out of reach of cats.
