Made with 12mm cedar wood. Width 170mm, depth 170mm, height 240mm, weight 700 grams. Hole diameter 32mm. Durable rubber string attached. The rubber strings (4) will be attached before shipping. Attach to the wood by tying (see photo 1). Unlike mass-produced items, this is a handmade piece. As natural wood is used, there may be knots, scratches, warping, unevenness, and color variations. Please purchase only if you understand and appreciate handmade items. Returns and exchanges are not accepted except for damage or malfunction upon delivery. This birdhouse is intended for small wild birds (sparrows, varied tits, great tits, coal tits, etc.). Wild birds will reuse old nesting materials or renovate the nest if they like it. They seem to feel secure with the old nesting material. There is absolutely no need for humans to clean the nest; the birds will remove anything they don't need, and they will adjust the height to suit their chicks. Be careful, as peeking inside during incubation may cause the birds to abandon their nest. It's best to peek after the chicks have hatched. There are many predators, so ideally, the birdhouse should be installed facing north, in a place with many trees and branches, at a height of 3 meters or more. 2 days ago
