This Woodstone® Build-in House Sparrow Nest Box is 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.
House Sparrows prefer to nest in groups or colonies, so this nest box has been designed with 2 chambers to allow them to breed in close proximity.
Clean the nesting box once a year when the youngsters have flown out. If a second brood follows, the nest box must be cleaned again in the late autumn. The reliability of the suspension must also be checked annually.
