There is a shortage of natural nesting sites, which is thought to be one of the major factors behind the decline of some of our once most-common birds. By putting up nest boxes, such as this, which replicates a bird\'s natural nesting preferences, you can encourage them to breed near your home. Different species prefer different nest boxes and our range has been designed by our team of ornithologists to optimum dimensions for the species concerned. Look out for regular visitors to your garden and choose a box which best suits their needs. You can check this using our hole size guide. This nest box is made from wood and has an attractive flamed surface and complimentary black roof. It is optimised with the addition of a nest box plate to protect nestlings from predators such as woodpeckers. This 34mm hole nest box is suitable for a family of sparrows and is also suitable for tits and Flycatchers.
