National Trust WoodStone 28mm Nest Box - Green

Constructed from a mix of concrete and wood fibres, WoodStone® nest boxes safeguard against attacks from predators including woodpeckers, cats and squirrels. The material insulates the nest which creates a more consistent internal temperature than an ordinary wooden box. This is especially important during the breeding season and ensures that young birds have a greater chance of survival. We recommend using aluminium nails to hang due to the weight of the nest box and to limit any damage caused to trees. 28mm Nest Boxes are used by Tree Sparrows, Blue Tits, Coal Tits and Great Tits. Weight approx.: 4kg Fixings/screws not included for: bird. for: blue tit, coal tit, crested tit, marsh tit, willow tit, tree sparrow.
