A comprehensive overview of the history of bird conservation and the development of nesting boxes over time has been lacking in the literature until now. This book serves as an interesting reference work for scientists and students, foresters and woodland owners, ornithologists, and nature enthusiasts, as it lists historical literature. However, it can also be a valuable guide for any garden owner in practical bird and nature conservation, providing new insights. Birds, like bats, are excellent and diligent helpers in biological pest control, proving that it is possible to manage pests without chemical means. The book includes construction instructions for a nesting box based on the latest findings, as well as important guidelines on how to properly maintain a nesting box. In addition to nesting boxes, other nesting aids are also considered.
