Making a bird box is a great way of using up those offcuts of wood that are too small for anything else. This is a really fun activity, especially for a rainy day! If doing this with kids make sure they are supervised at all times ππ±
Hereβs some more information on how I built my bird box. The Wildlife Trusts and RSPB have some great information on their websites too π€
πͺΊ Equipment πͺΊ
π± Wood offcuts
π± Screws or nails
π± Hammer (if using nails)
π± Drill
π± Saw
π± Ruler
π± Pencil
πͺΊ Box Dimensions πͺΊ
You donβt need to follow precise measurements - just build your box to suit the materials you have available. The offcuts I had determined the final dimensions of my box, and there was a little trial and error when cutting too π€ Iβve put my measurements below to give an idea but birds really arenβt fussy so work with what you have! I wrapped the front, back and sides around the bottom piece of wood.
Sides: 17cm front, 29cm back, 14.5cm bottom, 2cm thick
Front: 17cm tall, 16.5cm wide, 2.4cm thick
Roof: 24cm long, 16.5cm wide, 2.4cm thick
Bottom: 12cm wide, 14.5cm deep
Back: 43cm tall, 19.5cm wide
πͺΊ Hole openings πͺΊ
Having the right hole size is really important for attracting birds & keeping them safe.
π± 25mm for blue t**s
π± 28mm for great t**s
π± 38mm for sparrows
π± Robins prefer an open fronted box, so the front panel should be shorter than the sides to create a slot entrance at the top.
πͺΊ Where to site a bird box πͺΊ
Generally bird boxes shouldnβt be too close to each other to avoid competition, with the exception of sparrows who like their nests to be close to one another. Put your nest box in a quiet spot where it wonβt be subject to too much human disturbance.
Heights:
π± 2-4 metres blue t**s
π± 4-6 metres great t**s
π± Under the eaves of a house for sparrows
π± Robins like to be nestled in the undergrowth, so site robin nest boxes about a 1m off the ground with plenty of cover from plants.
π± You can add some rubber, felt or something else waterproof along the top of the nesting box where the roof joins the back. This will help to keep the box watertight and last for longer.
