Designed to support nesting blue tits, this beautifully presented gift set is perfect for the wildlife enthusiast in your life. This exclusive gift set includes an expertly designed wooden nest box with a 28mm hole, which will be used by several birds including blue, coal, marsh and willow tits, pied flycatchers and tree sparrows. The gift set also comes with a national trust garden bird identification chart to help identify which birds have taken up residence in the nest box. As a result of increased urbanisation and reduced mature woodland sites, birds are struggling to find suitable nesting sites. Installing a nest box in your garden will help to support local bird populations. Nest boxes also provide essential shelter for birds in winter. By purchasing this product, you are supporting the wildlife in your garden and the vital work carried out by the national trust to care for historic places, countryside and coastline, and the wildlife that lives there.
