Made nesting boxes (bird houses) today

I designed these bird nesting cavities over 20 years ago and they really work well.

For blue tit, great tit, (in US chickadee and titmouse etc) nuthatch and wrens (depending on hole size)

Though nesting cavities provide wild birds with nest sites in the early spring and summer, they are also critical in winter too. I recall one time when I checked one of my cavities finding 8 wrens in the same box. It was a hard winter’s night in December when the temperature was below zero for the 10th night running. Huddled together these birds looked like a solid mass of heads.

For blue tit, great tit, nuthatch,woodpecker and treecreeper

Placing nesting boxes at this time is important. Birds use them to over winter as winter housing on cold nights and it’s important that they locate them at this time, before the winter sets in. My cavities are round as the walls follow the round of the log. This takes much less nesting material to fill the cavity in nesting season, but there is nothing wrong with adding soft, warm nesting material for the winter time as this is not ritualistic courtship time. Simply remove the material prior to spring courtship time as nest building is critical to pairing off prior to and during mating with most cavity nesting birds and of course others too.

All our nesting boxes have removable or hinged lids for monitoring and clean-out.

We sell the nesting cavities for £19 plus shipping and handling. (For hinged lids instead of pegged as £3 more)

    How did you split or hollow out the back?

      On the bandsaw.

        Hi Paul,

        Could you do a video on how to do this safely on the bandsaw?
        Do you use a special blade?

          There are dangers unless you really know your bandsaw so I probably will not do a video, at this point any way.
