The Supa Multi-purpose Nest Box (Pack of 1) is suitable for many of the species of wild birds that are likely to nest in your garden. Can be used either in its original form or as an open fronted nesting box by removing the two screws which hold the front panel in place. Small gap in the base so the birds can easily clean the box out. The box should attract birds such as Robins, Pied Wagtail, Spotted Flycatcher, Great Tit, Blue Tits, Nuthatch and Tree Sparrows and many more species.
