Nest boxes for all varieties of garden birds. These are made to RSPB and NTO specifications with many features not found in cheap alternatives - we supply to many conservation projects.
It is best to put up nest boxes in winter so they are ready for birds in spring. To provide a home for nature is a joy in itself - simply watching wildlife use the habitat you have given is an instant reward. The same applies for all the mammals, birds and insects that also need suitable homes in the garden to mitigate the loss of natural habitats.
