The nesting box is made of solid larch wood and completed with pine boards, the special feature is the slit-shaped opening. I once saw a similar bird house in the Bavarian Forest - that's why I call it Bavarian. It is suitable for finches and some titmice. The birds can stop in the longitudinal exit hole, look around and then fly out. It gives them a sense of security. The narrow opening prevents larger species from settling. The front panel is also reinforced with an internal bar - another safety feature, especially against cats.
The exit slit or opening is 33 mm high and can be adjusted to your needs.
