The Schwegler FNA is available in two options;
1FNA - comes with side entrance
2FNA - comes with front entrance
The Schwegler 1FNA is a durable nest box that was specifically developed for Lesser Kestrels. However it is equally popular with species requiring a spacious nesting compartment. The design combines relatively compact dimensions with good insulation, especially when installed in sunny spots.
Cleaning: The box can be easily accessed using the inspection flap at the rear.
Material: Schwegler wood concrete.
Siting: At least 4 m above the ground. Please ensure unobstructed access for birds entering and leaving the box.
Includes platform below the entrance-hole for convenient access of its occupants.
Interior of nesting chamber: height 17 x width 36 x depth 16 cm.
1FNA: H 24 x D 23.5 x L 54 cm.
2FNA: H 24 x D 25 x L 43 cm.
1FNA: 12.6 kgs.
2FNA: 11.3 kgs.
Diameter of entrance hole: 65 mm.
Positioning: On external walls of buildings of all kind, including churches and industrial buildings, poles, etc.
Suitable for: Lesser Kestrel, Little Owl, Scops Owl, Hoopoe, Roller, Jackdaw, Starling, Spotless Starling.
Schwegler nest box designs mirror natural holes, with internal dimensions that are similar to the holes made by woodpeckers or caused by decay in old trees.
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.
