If you are looking for outstanding performance and maximum dependability from a natural timber box, the CedarPLUS Modern nest box is a great choice. It is available with two hole sizes: To let any small birds use the box choose the 32mm hole - suitable for great, marsh and coal tits, redstart, nuthatch, pied flycatcher, house sparrow and tree sparrows. To allow access only to blue, marsh and coal tits (and possibly wrens), choose the 26mm hole. All other species will be excluded by the smaller entrance.
Both sizes have the following features:
* 19 and 25mm thickness Canadian cedar wood for excellent insulation and strength.
* Hinged inspection door with rust-proof catch.
* Material: Canadian cedar
* Height: 370mm
* Width: 156mm
* Depth: 175mm
