Woodstone Bilbao 28mm Nest Box - Brown

Looking for a nest box that lasts for years and genuinely helps your garden birds thrive? This WoodStone® nest box with a 28mm entrance hole is tailor-made for smaller tit species like Blue Tits, Coal Tits, and Marsh Tits - and yes, they love it.

Made from a clever blend of concrete and wood fibres, this nest box is built to last and offers excellent insulation. Unlike traditional wooden boxes, it keeps the inside temperature more stable - which is a real game-changer during the breeding season. More stability = better chances of survival for chicks.

And predators? Not a chance. Cats, woodpeckers, and squirrels are no match for this tough design. The black front panel makes it easy to number boxes during research studies - or just adds a sleek touch to your garden setup.

Tip: Use aluminium nails when mounting to protect both your tree and to support the weight (around 7 kg) of this sturdy nest box.
