Schwegler No. 4 nest box

Owl boxes are installed in parks and forests, not only to promote the diversity of species but also as a means of controlling the mouse population. The Owl Boxes No. 4 and No. 5 are intended as a substitute for the large holes made by woodpeckers in old trees. These are often taken over by other types of animals, such as squirrels. Woodpeckers occasionally use these nest boxes as an overnight roost, but each year they will drill out a new hole in a tree to lay their eggs and raise their young.
