Hi guys! Thanks for all your questions, as it spurred me to do a post showing the little things we have added to make your birdhouse safe and cozy.
Photo 1: The climbing wall we develped with the factory to give chicks some extra grip (there's a debate about whether it's actually needed, but we included it - as it anyway keeps the chicks entertained!). The size of the hole and the height from the floor were taken from BirdLife International guidelines.
Photo 2: An actual nest built in the birdhouse on our balcony. The area of the floor comes from the chickadee version of the tried-and-true round Gilbertson birdhouse, with extra room in the corners (the triangle is Studio Tolvanen's innovation, and you can see that the area actually used is the round area in the center, so no worries there!).
Photo 3: It comes with a wood hanger made from heat-treated Nordic Swan certifed pine (so it's rot resistant without any toxic chemicals). It's angled on top so the birdhouse hangs against the wall but can be easily removed by lifting up and out. The back is open so it can be cleaned each nesting season. We have left ours outside in Finland during -30 C (even poured water over it, let it freeze, and brought it inside and immediately under hot water). That said, it is ceramic and if you want to be absolutely sure you should bring it in over the winter.
There is space around the wood hanger to allow for variation in handmade ceramics and also to give a little extra venthilation inside.
Photo 4: Birdhouses were ceramic before they were wood. For centuries, humans have hung ceramic birdhouses on architecture to house our feathered friends. It seems counter-intuitive, but ceramic has been used because it absorbs heat and slows the transfer to the inside, so the result is that it keeps interiors cooler longer in extreme heat. At night when it is cooler outside, it stays warmer - so overall the temperatures don't swing as much as wood. That said, you should still place your birdhouse out of direct sunlight in the afternoon. No one wants to be directly in the afternoon sun.
Stay tuned for a post on the history of ceramic birdhouses!
