Wildlife World Tree Creeper Bird Box Treecreepers love to nest behind dislodged bark strips on trees, so this Wildlife World box that replicates this environment is absolutely perfect for them! Unlike the majority of bird boxes, access to this one is made via the sides rather than the front, as the front has the silver birch bark where most holes are. Position the box between 1.5 & 3m from the ground of a mature tree, facing between North & Southeast & ideally in the quietest location that fits these needs.
