General description These multi-hole nest boxes offer a one-stop solution for housing the birds that visit your garden. The entrance is interchangeable between open-fronted (perfect for Robins, Wrens, and Pied Wagtails), a 28mm hole, and a 32mm hole. Simply pop out the unneeded entrances, and the bird box is ready to provide shelter. Offering 1.5cm thick wooden walls for insulation, these birdhouses come in a great value pack of four, allowing you to position them at different vantage points.
