Schwegler nest boxes are famous for their quality and durability. Made from Woodcrete, a breathable blend of wood, concrete and clay, they will not warp, rot, leak or crack. They are also guaranteed to last for 20-25 years. Woodcrete is good at insulating and so boxes made from this material provide a consistent thermal environment throughout the year for their inhabitants. It is also tough, making it more difficult for predators to gain access to nesting birds and their eggs.
Schwegler boxes are available in a huge range of models, each meticulously designed to suit a particular species (or collection of species) and/or siting location.
