The Schwegler Nest Box 1BFN is a lightweight box originally developed for Lesser Kestrels. However it is equally popular with other species. The design allows for easy installation in walls, cliffs, etc. The Schwegler 1BFN includes a platform below the entrance hole for convenient access.
Siting: at least 4 m above the ground. Please ensure unobstructed access for birds entering and leaving the box.
Suitable for: Lesser Kestrel, Little Owl, Scops Owl, Hoopoe, Roller, Jackdaw, Starling, Spotless Starling.
Internal dimensions: approx. 18 x 18 x 30 cm.
External dimensions: approx. 19 x 19 x 34 cm.
Diameter of entrance hole: 65 mm.
Positioning: on external walls of buildings of all kind, including churches and industrial buildings, poles, etc. The 1BFN is mostly built into external walls.
Cleaning: The box can be easily accessed using the inspection flap at the rear.
Material: Plant fibre (100% asbestos-free) and Sschwegler wood-concrete.
Schwegler nests will last 25+ years 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. 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.
