Nest Box 3SV

The Schwegler 3SV has a deep entrance hole which has been demonstrated to provide highly effective protection from predators such as cats and martens. The design also mimics natural nest sites and the large entrance hole results in a well-lit interior that encourages occupation. The nesting area is easily accessible by removing the front panel, making it easy to inspect and clean.

Built using wood-concrete; an exceedingly durable, rot-proof and breathable natural material designed to mimic the properties of natural nest sites, the 3SV nest box is available with 3 sizes of entrance holes:
