Half-open nest box HOP1 – recessed, wood-concrete for black redstart | Unitura

The HOP1 is a semi-open wood-concrete nest box that is built into the masonry. The box is designed for species that breed in semi-open cavities, such as the black redstart and the white wagtail.

• Made entirely of wood-concrete: durable and maintenance-free
• Shallow, so it can also be built into facades from the 1950s and 60s with a narrow cavity
• Unobtrusive design that fits in almost any type of facade
• Thickened rim around the entrance with a sloping edge, making it difficult for rainwater to enter the box
• Can be finished so that the box is almost invisible in the facade

Tip: spread the boxes across the facade. Black redstarts are territorial, so clustering them is not very useful.

Placement

Fully incorporate the box into the facade surface. If a box protrudes partially from the facade, rainwater may collect on the top and penetrate moisture into the structure. If you still place the box partially outside the facade surface, install a roof or similar water-repellent structure above the box.
