This built-in nesting box is suitable for new construction to compensate for house sparrow nest sites in facades. The internal dimensions are ideal for nesting house sparrows. The height of this built-in brick fits perfectly into a 4-layer wall format. Since sparrows live in colonies, installing several built-in bricks together is recommended. The built-in nest box is also frequently inhabited by other species, such as tits. This built-in nest box is made of WoodStone and can be opened at the front for cleaning, if desired. WoodStone is a mix of 100% FSC\u00ae-certified wood fibres and concrete. This robust material is environmentally sustainable and will last for decades.<\/p>\n","protected":false},"excerpt":{"rendered":"
