Installing a House Martin nest beneath the eaves of your house or other building is an excellent way to help your local House Martin population. House Martins build natural nest cups out of mud which requires a significant amount of energy. In dry springs, mud can be in short supply - this makes it particularly difficult for them to build a suitable nest bowl. By utilising a ready-made nest they can devote much more energy to breeding and raising their chicks.
This nest cup consists of a moulded resin and concrete bowl which is fixed to a backing plate made from recycled waste plastic. A plastic roof helps to keep the nest cup dry and a drainage hole in the bottom of the cup allows any moisture to drain.
The nest should be sited directly under the eaves at a minimum height of 2m. If possible, avoid installing it directly over windows or doors as dropping can build up beneath occupied nests. As House Martins like to nest in colonies, installing several boxes near to eachother may encourage several breeding pairs to colonise the building.
Installation is very easy – the nest slots over two screws and then is secured in place using a third screw hole at the base of the back board.
