Blue Tit / Coal Tit Box
Blue tit, coal tit, marsh tit
A 25 mm hole keeps out house sparrows and great tits, giving blue tits exclusive use.
Where & when
- Mount
- 1.5–3 m (5–10 ft) on a tree or wall
- Facing
- North to east, away from strong sun and prevailing wind
- When
- Put up by February; clean out Sept–Jan
Cut list (15 mm timber · plank 170 × 1340 mm)
| Part | Qty | W × L (mm) | Notes |
|---|---|---|---|
| Back | 1 | 150 × 310 | Extra length top & bottom for fixing |
| Front | 1 | 150 × 200 | 25 mm hole, centre 150 mm from bottom |
| Side | 2 | 120 × 250 | Tapers from 250 mm (back) to 200 mm (front) |
| Base | 1 | 120 × 120 | Drill 4 × 6 mm drainage holes; trim corners |
| Roof | 1 | 170 × 180 | Overhangs front to shed rain |
Step-by-step
- Mark out all pieces on one plank of rough-sawn untreated timber (15 mm softwood, or exterior plywood) using the cut list. Mark each piece's name in pencil.
- Cut the pieces. For the two sides, measure 250 mm on the back edge and 200 mm on the front edge and saw the slope between them.
- Drill the 25 mm entrance hole in the front panel with a hole saw or flat bit, centred about 50 mm below the top edge (at least 125 mm above the floor so chicks are safe from cats and woodpeckers). Do not add a perch — it helps predators.
- Drill four 6 mm drainage holes in the base and trim the corners slightly for extra drainage.
- Fix the sides to the back with 40 mm galvanised screws or ring-shank nails (pre-drill to avoid splitting), keeping the bottom edges flush 60 mm up from the bottom of the back.
- Fit the base between the sides, then fix the front.
- Fix the roof with a strip of rubber (old inner tube) or a brass hinge along the back edge, and a hook-and-eye catch at the side so you can clean the box out each autumn.
- Mount: 1.5–3 m (5–10 ft) on a tree or wall. Aspect: North to east, away from strong sun and prevailing wind. Tilt slightly forward so rain runs off the roof.
- Leave the wood untreated inside. If you treat the outside, use a water-based, wildlife-safe preservative and let it dry fully before putting up.
