This box is best sited on solitary trees, quiet places on the edge of woodlands, barns in open countryside and silos, amongst others. In urban areas large buildings, high walls, chimneys, industrial buildings and churches can all be used. In the absence of trees the boxes can be installed on high poles to assist the birds in their hunt for mice. Ensure the box is at a minimum height of 2.5 to 3 m (optimal height is 6 to 8 m). Place the box facing south-east or away from the prevailing wind. Alternatively it can be located under rafters, in recesses on historic buildings or in gaps in masonry.
Made using Schwegler's wood-concrete, this exceedingly durable, rot-proof and breathable material is designed to mimic the properties of natural nest sites and last 25 years. You can further encourage nesting by placing a moistened mixture of coarse sawdust, wood shavings and washed sand inside the nesting chamber.

Schwegler nests will last decades and are readily adopted by birds. This means decades of breeding success in real life conditions. These nest boxes have been developed in close collaboration with leading ornithologists, nature conservation organisations, Government conservation agencies and forestry experts, and are backed up by decades of experience and knowledge. In each nest box the size of the brood chamber, diameter of the entrance hole and many other features have been adapted to the needs and behaviour of the animals themselves. Experiments by bird protection organisations worldwide have demonstrated that the highest density of bird populations (i.e., breeding pairs per hectare) is achieved with Schwegler nest boxes.
