This highly successful design means you can now provide house martin nesting sites on any external wall regardless of whether it has eaves or not. Made using Schwegler's patented wood-concrete (an exceedingly durable, rot-proof and breathable natural material designed to mimic the properties of natural nest sites and last up to 25 years), this contemporary design is an attractive addition to urban areas.
Ensure the nest is located at least 2 m above the ground. The nest can be installed on any unobstructed facade without an overhanging roof, or alternatively directly under overhanging eaves. Ensure the nest is on the outside of the building (rather than inside the roof) on the sheltered side. Each individual nest can be removed separately for cleaning and inspection. We also recommend purchasing the Schwegler Droppings Board for this terrace to keep the area under the nests free from droppings.

Schwegler nests will last at least 20-25 years and are readily adopted by birds. This means several 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. They are made of a unique wood-concrete material, an entirely natural product consisting of 75% wood and various additives to compensate for climatic changes. This provides insulation against temperature fluctuations, allows air to pass through the walls, and prevents the formation of condensation which often occurs in nest boxes made of plastic, stone or entirely of concrete. This material is also much longer lasting and weather-resistant than wood, and is strong enough to withstand the attention of woodpeckers.
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.
