Schwegler 5KL Nuthatch Nestbox

Nuthatches prefer to occupy larger boxes like the Nos. 4 and 5 Owl Boxes, because of their larger internal diameter, rather than alternatively available smaller nest boxes. They fill the large entrance hole with clay and damp soil until it matches their required width of 32 mm, thus preventing larger birds from gaining access. To overcome this, the 5KL has been designed specifically for this uniquely agile species.

No sawdust or other similar material need to be placed inside because the Nuthatch, in common with all other small birds, will construct its own nest.
