Schwegler No. 9A House Martin Double Nests

It is increasingly difficult for House Martins to find suitable nest-building material in our modern world. The mud they do find, if any, is often poor quality. In addition, the walls of buildings are nowadays often very smooth As a result, nests tend to fall down, sometimes with the nestlings inside. In many places, the vibration caused by heavy vehicles shakes the nests loose.

Our SCHWEGLER Nests, made of wood-concrete with a 75% wood content affixed to an exterior plywood backing are far superior to natural nests and are a direct way to help House Martins.

Siting and Positioning:
Under eaves on the external walls of buildings. House Martins never nest inside buildings. Install on the sheltered side of the building. Against a light background or wooden boards. Martins tend to return to the same nesting site year after year. Consequently it may take some time before they colonise new areas. Once they have chosen a nesting site there are virtually no limits to the size of a colony of House Martin nests.  Minimum height 2 m.  
 
Cleaning:
Can be used for years without cleaning. However, if possible it is advisable to inspect the nests frequently and to clean them if necessary.
