The nest box is designed to encourage Wrens as they like to nest near the ground, in undergrowth. They are not particularly good flyers, preferring to hop about in the undergrowth. They like shady places - in hedges, thickets, heavily overgrown areas and bushes as well as balconies. The Wren Roundhouse is available in ivy green and autumn light red.
Hang the nest box in undergrowth, in a shady place. It can also be placed upon a pile of brushwood or garden clippings, for example. If hung in a totally unobstructed place it will also attract other types of birds that nest in holes and cavities, including Blue-, Coal- and Great Tits, as well as Tree and House Sparrows.
These Woodcrete nest boxes are famous for their durability - lasting for at least 20-25 years. Woodcrete is a blend of wood, concrete and clay which will not rot, leak, crack or warp. They are backed by leading ornithologists, nature conservation organisations, government agencies and forestry experts. Schwegler boxes have the highest occupation rates of all nest boxes and are carefully designed to mimic natural nest sites and provide a stable environment for chick rearing and winter roosting.
Diameter of the sphere: 18.5cm. Entrance hole: 30mm x 27mm. Complete with hanging cable (galvanized steel) of 20cm.

They are simple to install, inspect and clean.
Schwegler have a patented method of installation on trees prevents the tree trunk from growing over the hanger from which the box is suspended.
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 nest 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.
