Living with Birds Modular House Martin Nest Semi-finished

In areas which pools of clay, loam or clay soil are available and accesible for martins, the 13B can be provided as a semi-fnished nest for the house martins to finish themselves.

The advantages of the semi-finished nest is that they provide a secure place for breeding and cannot fall off, which can happen with the martins own construction, due to unsuitable clay composition. The optimum solution is to attach the semi-finished nest alternately with a finished nest.
