These nest boxes are made from sustainably sourced North American cedar, the thick (19mm) walls offering excellent insulation. They need no painting, varnish or preservative and will age gracefully to a delightful silver-grey.
Recommended by National Nest Box Week, they can be fixed to a tree, a post or a wall.
Choose the 32mm hole if you want any small bird to consider it as a future home - nuthatches, and of the tit family, redstasts of flycatchers. If you're just looking to house our smaller friends (wrens, blue or coal tits) choose the smaller 26mm hole.
